설명:
The ABCD1 (ATP-binding cassette subfamily D member 1) gene, located on the X chromosome (Xq28), encodes a peroxisomal transmembrane protein responsible for transporting very long-chain fatty acids (VLCFAs) into peroxisomes for β-oxidation. Widely expressed but particularly prominent in the brain, adrenal glands, and liver, ABCD1 is critical for maintaining lipid homeostasis. Mutations in ABCD1 cause X-linked adrenoleukodystrophy (X-ALD), a neurodegenerative disorder characterized by VLCFA accumulation, demyelination, adrenal insufficiency, and progressive neurological decline. Clinical manifestations vary widely, ranging from asymptomatic carriers to a severe, fatal childhood form. Primarily affecting males (with an estimated incidence of ~1 in 17,000 newborns), X-ALD has been included in newborn screening programs in many U.S. states [1-2]. The correlation between specific mutations and symptoms remains unclear, and VLCFA measurement cannot reliably predict disease-specific outcomes such as adrenal insufficiency or neurological decline. Current therapeutic approaches focus on gene repair or mitigating secondary effects like oxidative stress [3].
The Abcd1-KO mouse, a gene knockout model generated by deleting exon 2 of the mouse Abcd1 gene (homologous to human ABCD1), serves as a valuable tool for studying the pathogenesis of X-ALD and developing therapeutic interventions.

설명:
P-glycoprotein (P-gp), also known as multidrug resistance protein 1 (MDR1), is an ATP-binding cassette transporter that acts as a biological barrier by expelling toxins and foreign substances from cells. P-gp is capable of transporting many structurally and functionally different compounds out of cells [1]. However, the mechanism of MDR1 also prevents the uptake of many cancer treatment drugs by cells, leading to multidrug resistance (MDR) [2]. In normal organisms, MDR1’s distribution in the blood-brain barrier and blood-placenta barrier prevents exogenous drugs and toxins from entering the central nervous system and placenta of the organism, thereby protecting the organism and enabling it to perform normal physiological functions. In pathological conditions, however, the MDR1 in the blood-brain barrier prevents drugs from entering the central nervous system, and in tumor cells, leads to the development of MDR. The evolution of MDR remains one of the major obstacles to controlling or curing cancer [3-4].
In humans, the MDR1 protein is encoded by the ABCB1 gene. In mice, two closely located genes, Abcb1a and Abcb1b, encode the MDR1a and MDR1b subtypes of this protein. Mouse MDR1a and MDR1b have 80% homology with human MDR1. MDR1a and MDR1b have the same function as human MDR1 protein in resisting anticancer drugs. Although mouse MDR1a and MDR1b proteins are distributed in different tissues of the body, their overall distribution is consistent with that of human MDR1 protein [5-6]. In summary, the distribution and function of mouse MDR1a and MDR1b are consistent with those of human MDR1.
This strain is an MDR1 knockout model, in which the human ABCB1 gene’s homologous genes, Abcb1a and Abcb1b, were knocked out in mice using gene editing technology. This model lacks the expression of MDR1 protein and can be used for research in areas such as blood-brain barrier permeability-related diseases and multidrug resistance of anti-tumor drugs.

C57BL/6JCya
상태:
설명:
Calcitonin-related polypeptide alpha (CALCA) is a protein-encoded gene, also known as CALC1, CGRP, or CGRP-α. Multiple genetic factors and epigenetic modifications regulate CALCA gene expression, and it forms peptide hormones calcitonin (CT), α-isoform of calcitonin gene-related peptide (CGRP), and katacalcin through tissue-specific RNA alternative splicing and non-active precursor protein cleavage in transcription and translation. Calcitonin is synthesized and secreted by thyroid parafollicular cells, mainly involved in regulating calcium levels and phosphorus metabolism in bones and kidneys. It can reduce the concentration of calcium and phosphorus in the plasma and inhibit the absorption of calcium and phosphorus. CGRP mainly acts as a vasodilator and antimicrobial peptide, which can cause dilatation of coronary arteries, cerebral vessels, and systemic vessels, and help to regulate blood pressure. CGRP is also widely distributed in the pain pathways of the peripheral and central nervous system (CNS) of the human body, and its receptors are also expressed in the pain pathways. CGRP participates in the transmission of pain signals from the periphery to the CNS and plays a key role in pain regulation, which is related to the pathogenesis of a variety of pain diseases and related syndromes, including somatic pain, visceral pain, neuropathic pain, inflammatory pain, and migraine. Katacalcin mainly exists as a peptide that can effectively lower plasma calcium, and its effect of lowering serum calcium levels is almost the same as that of calcitonin. CALCA gene polymorphism is associated with a variety of diseases, including reflex sympathetic dystrophy syndrome, complex regional pain syndrome, ischemic stroke, Parkinson's disease, ovarian cancer, bone mineral density, migraine, schizophrenia, bipolar disorder, and primary hypertension [1-5]. CALCA is a potential target for new therapies for a variety of diseases. Currently, various CALCA antagonists are being developed for the treatment of migraine and primary hypertension, and research on targeting CALCA for diseases such as Alzheimer's disease and Parkinson's disease is also ongoing [6-7].
This strain is a humanized mouse model of the Calca gene. Using gene editing technology, the base sequence of the mouse Calca gene from the start codon to the 3’UTR region was replaced by the corresponding sequence in the human CALCA gene, while the 5’UTR region of the mouse Calca gene was retained. Homozygous B6-hCALCA mice are viable and fertile and can be used to study the mechanisms of various physiological and pathological processes such as blood pressure regulation, cell proliferation, cell apoptosis, vascular biology, physiological bone marrow production, inflammation, tumor growth, and research on CALCA-targeted migraine drugs and therapies.

상태:
설명:
The Triggering Receptor Expressed on Myeloid Cells 1 (TREM1) gene encodes a transmembrane protein, also known as CD354, primarily expressed on myeloid cells such as neutrophils, monocytes, and macrophages, with expression also observed in dendritic cells, microglia, osteoclasts, platelets, and even some epithelial and endothelial cells [1]. Upon activation, the TREM1 protein amplifies inflammatory responses, often synergizing with Toll-like receptor (TLR) and NOD-like receptor (NLR) signaling pathways. This leads to the robust production and release of pro-inflammatory cytokines and chemokines, enhanced degranulation, phagocytosis, and respiratory burst in neutrophils and macrophages, and even promotes dendritic cell maturation [2]. A soluble form of TREM1 (sTREM1) also exists, which can act as a decoy receptor to modulate inflammation and serves as a biomarker for various inflammatory conditions [3]. Dysregulated TREM1 activity is implicated in a wide range of diseases, including infectious diseases like sepsis and pneumonia, chronic inflammatory conditions such as inflammatory bowel disease, atherosclerosis, rheumatoid arthritis, and various cancers (e.g., glioma, hepatocellular carcinoma, lung adenocarcinoma, breast, colon, and pancreatic cancers), as well as neurodegenerative disorders like Parkinson's and Alzheimer's disease, and kidney-related diseases [2-5].
The B6-hTREM1 mouse is a humanized model, constructed by replacing the mouse Trem1 signal peptide (aa. 1-20) and endogenous extracellular domain (aa. 21-202) with the human TREM1 signal peptide (aa. 1-20) and extracellular domain (aa. 21-205), while preserving the murine aa. 203-230. B6-hTREM1 mice can be used for research into the pathogenesis of various inflammatory diseases, cancers, neurodegenerative diseases, and kidney-related diseases, as well as for the screening, development, and safety evaluation of TREM1-targeted drugs.

설명:
The Transferrin receptor (TFRC) gene encodes Transferrin Receptor 1 (TFR1), a protein that is expressed at low levels in most normal cells but shows increased expression in highly proliferative cells, such as basal epidermal cells, intestinal epithelium, and certain activated immune cells. Brain capillary endothelial cells, which constitute the blood-brain barrier (BBB), also express this receptor at high levels [1]. TFR1 plays a critical role in maintaining iron metabolism and homeostasis by facilitating receptor-mediated endocytosis of iron-bound transferrin (Tf) via Tf cycling, thereby promoting iron uptake [2]. Cellular iron deficiency can lead to apoptosis, while cellular transformation requires substantial iron to sustain proliferation, with iron overload contributing to tumor progression. The high expression of TFR1 in many tumors makes it a potential tumor marker, offering a target for therapies to inhibit tumor growth and metastasis [1]. Moreover, TFR1 is implicated in anemia and iron metabolism disorders. Studies have shown that elevated TFR1 expression in cardiomyocytes is associated with exacerbated inflammation in myocarditis patients [3]. Various clinical drugs targeting TFR1 are currently under development, including antisense oligonucleotides (ASOs), antibody-drug conjugates (ADCs), and antibody-oligonucleotide conjugates, applicable to diseases such as cancer, anemia, and neurodegenerative disorders. Research indicates that enhancing antibody transport across the blood-brain barrier via TFR1, by forming specific bispecific antibodies with anti-β-amyloid antibodies, can improve therapeutic outcomes in Alzheimer's patients [4-5]. As research progresses, TFR1 is expected to become an effective clinical target for multiple diseases and a synergistic target for drug delivery across the blood-brain barrier (BBB).
Parkinson's disease (PD) is a neurodegenerative disease with a high prevalence mainly in the middle-aged and elderly population. It is the second most common neurodegenerative disease after Alzheimer's disease (AD). The main clinical symptoms include resting tremors, limb stiffness, bradykinesia, loss of voluntary movement, etc. The typical pathological process of PD is the formation of Lewy bodies (LB) in the central nervous system (CNS), which results in the gradual death and loss of dopaminergic neurons, leading to the disease [6-7]. The main components of Lewy bodies are insoluble aggregates of abnormal α-synuclein (α-syn), and the SNCA gene, which encodes α-synuclein, is one of the key causative genes in Parkinson's disease. Mutations in this gene cause overexpression of α-syn, leading to the formation of Lewy bodies, ultimately leading to PD [8]. In addition, SNCA mutations are also associated with diseases such as dementia with Lewy bodies (DLB) and multiple system atrophy (MSA).
B6-huTFRC/huSNCA(3'UTR) mice are a dual-gene humanized model generated by crossing B6-huTFRC mice (Catalog No.: C001860) with B6-hSNCA (3'UTR) mice (Catalog No.: C001698). This model can be used for research on neurodegenerative diseases such as Parkinson's disease (PD), dementia with Lewy bodies (DLB), and multiple system atrophy (MSA), as well as iron metabolism disorders and tumorigenesis and development. It is also applicable for the development of TFRC/SNCA-targeted drugs.

Rett syndrome (RTT) is an X-linked dominant neurodevelopmental disorder primarily affecting female infants and young children, with an incidence of approximately 1 in 10,000 to 15,000 females. Characteristic clinical features include intellectual disability, loss of language skills, stereotypic hand movements, and gait disturbances. Affected individuals typically experience a period of normal development, followed by deceleration in head circumference growth between 6 to 18 months of age, and subsequent regression of acquired motor and cognitive abilities. Overt impairments in cognition and motor function generally emerge within 1 to 2 years. Mutations in the methyl-CpG-binding protein 2 (MECP2) gene are responsible for over 90% of RTT cases. MECP2 is a nuclear protein that binds methylated DNA to modulate gene transcription. MECP2 gene duplications lead to MECP2 duplication syndrome (MDS), while MECP2 deficiency disrupts central nervous system maturation, adversely affecting learning and memory, culminating in the clinical manifestations of RTT.
Current therapeutic strategies for RTT primarily revolve around gene supplementation using adeno-associated virus (AAV) vectors to deliver functional human MECP2 genes to compensate for the endogenous deficiency. However, the substantial size of the MECP2 gene surpasses the packaging capacity of most viral vectors, and overexpression of MECP2 poses a risk of severe neurological complications. These challenges have significantly impeded the progress of gene supplementation therapies. Consequently, the focus has shifted towards DNA/RNA editing approaches aimed at correcting MECP2 mutations and restoring physiological levels of MECP2 protein expression. Notably, several research groups have successfully employed CRISPR-based gene editing technologies to rectify MECP2 mutations in induced pluripotent stem cells (iPSCs) or patient-derived cells ex vivo [1-2]. Given the pivotal role of animal models in preclinical research, the development of humanized mouse models expressing the human MECP2 gene is crucial. These models facilitate the transition of gene therapy candidates—encompassing small nucleic acids, CRISPR-based editors, base editors, and RNA editing technologies—into clinical stages [3-4].
This strain is a humanized MECP2 gene mouse model, generated by replacing the endogenous mouse Mecp2 gene with the human MECP2 gene harboring the T158M mutation through embryonic stem cell targeting techniques. This mutation represents the most common human RTT-associated missense mutation in MECP2. Studies have shown that mice carrying this mutation recapitulate many clinical features of RTT [5].

설명:
The IGHMBP2 (Immunoglobulin mu binding protein 2) gene encodes an ATP-dependent helicase that is expressed throughout the body and contains a helicase structural domain, a single-stranded nucleic acid binding domain, and one zinc finger motif. It is involved in the regulation of DNA replication, mRNA splicing, transcription, and translation. Mutations in IGHMBP2 can lead to two different types of diseases: spinal muscular atrophy with respiratory distress type 1 (SMARD1) and Charcot-Marie-Tooth disease type 2S (CMT2S).
Spinal muscular atrophy with respiratory distress type 1 (SMARD1) is a rare autosomal recessive motor neuron disease, with its main clinical symptom being diaphragmatic paralysis leading to respiratory distress, occurring mostly in infants aged 6 to 12 months. In addition, SMARD1 can also cause severe muscle atrophy that progresses from the distal to the proximal limbs, intrauterine growth retardation, weak crying, and sensory and autonomic nervous system defects [1]. Restrictive cardiomyopathy may be one of the phenotypes of SMARD1 [2]. Charcot-Marie-Tooth disease type 2S (CMT2S) is a rare hereditary neurological disease and is a subtype of Charcot-Marie-Tooth disease type 2 (CMT2). CMT2 is a group of hereditary peripheral neuropathies characterized by abnormal fibers or axons extending from the nerve cell body to muscles or sensory organs, reducing the strength of nerve impulses. The clinical characteristics of CMT2S include symmetrical distal limb weakness and muscle atrophy, with severe peripheral nerve damage.
Currently, ASO drugs and AAV-based gene therapy have emerged in the IGHMBP2-targeted drug pipeline for the treatment of SMARD1 and CMT2. Gene therapy is expected to become one of the most promising treatments for these diseases. However, since most ASO, AAV-based gene therapy, etc., act on the human IGHMBP2 gene, considering the differences between animals and humans in genes, humanizing the mouse gene will help promote the further clinical translation of therapies targeting IGHMBP2. This strain is a mouse Ighmbp2 gene humanized model and can be used for research on SMARD1 and CMT2S. The homozygous B6-hIGHMBP2 mice are viable and fertile. In addition, based on the independently developed TurboKnockout fusion BAC recombination technology, Cyagen can also generate hot mutation models based on this strain and provide customized services for specific mutations to meet the experimental needs in pharmacology and other fields related to SMARD1 and CMT2S.

Parkinson's disease (PD) is a degenerative disease of the nervous system that occurs mostly in middle-aged and elderly people and is the second most common neurodegenerative disease after Alzheimer's disease (AD). Clinical symptoms of PD are characterized by resting tremors, limb stiffness, bradykinesia, and lack of voluntary movement. The typical pathology of PD is characterized by the formation of Lewy bodies (LB) in the central nervous system (CNS). This process leads to the progressive death and loss of dopaminergic neurons, ultimately resulting in the development of Parkinson's disease. Lewy bodies are mainly composed of insoluble aggregates of abnormal α-synuclein (α-syn).
The SNCA gene, one of the key pathogenic genes in Parkinson's disease, encodes α-syn. Mutations in SNCA can cause overexpression of α-syn, which leads to the formation of Lewy bodies and ultimately PD. Therefore, the SNCA gene is considered an effective drug target for the treatment of PD [1].
Gene therapy is one of the ways to treat PD, among which the development prospects of SNCA-targeted drugs are particularly prominent. The drug pipelines targeting SNCA are widely laid out, and ASO, siRNA, and CRISPR therapies have emerged [2].
This strain is a mouse Snca gene humanized model and can be used for research on PD. The homozygous B6-hSNCA mice are viable and fertile. Leveraging its proprietary TurboKnockout fusion BAC recombination technology, Cyagen can also generate hot mutation models based on this strain and provide customized services for specific mutations to meet the experimental needs in pharmacology and other fields related to PD.

Lewy bodies are mainly composed of insoluble aggregates of abnormal α-synuclein (α-syn).
The SNCA gene, one of the key pathogenic genes in Parkinson's disease, encodes α-syn. Mutations in SNCA can cause overexpression of α-syn, which leads to the formation of Lewy bodies and ultimately PD. Therefore, the SNCA gene is considered an effective drug target for the treatment of PD [1].
Gene therapy is one of the ways to treat PD, among which the development prospects of SNCA-targeted drugs are particularly prominent. The drug pipelines targeting SNCA are widely laid out, and ASO, siRNA, and CRISPR therapies have emerged [2].
This strain is a mouse Snca gene humanized model and can be used for research on PD. The homozygous B6-hSNCA mice are viable and fertile. Leveraging its proprietary TurboKnockout fusion BAC recombination technology, Cyagen can also generate hot mutation models based on this strain and provide customized services for specific mutations to meet the experimental needs in pharmacology and other fields related to PD.

설명:
Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, is a fatal progressive neurodegenerative disease characterized by the degeneration and death of motor neurons in the central nervous system. This loss of motor neurons leads to progressive muscle weakness and atrophy, ultimately culminating in the complete loss of voluntary muscle control. Consequently, ALS can induce speech, swallowing, and respiratory difficulties [1]. Critically, unlike Alzheimer's disease, ALS does not necessarily impact higher-order cognitive functions. Remarkably, patients in advanced stages of the disease can maintain clear thinking and retain their premorbid memory, personality, and intelligence. Several genes have been identified as causative factors in ALS, including SOD1, ALS2, TARDBP, and FUS. Among them, TARDBP (TAR DNA-binding protein) is a gene encoding a protein involved in diverse cellular functions, including facilitating nuclear protein import, regulating circadian rhythms, and maintaining protein stability [2]. Mutations in the TARDBP gene are linked to ALS. These mutations can lead to abnormal TDP-43 protein accumulation and its mislocalization to the cytoplasm, a key pathological hallmark of the disease [3].
TARDBP-targeted therapy is mainly based on monoclonal antibody drugs, most of which are still in the preclinical stage of development. Oligonucleotides such as ASO and gene therapy have also been reported in the literature. These drugs are mainly used for the treatment of neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). TARDBP is a new and popular target for the treatment of ALS. Preclinical disease research models are mainly transgenic (TG) or point mutation (PM) mice. To advance TARDBP-targeted drug therapies, especially gene and oligonucleotide therapies, Cyagen has independently developed a mouse Tardbp gene humanized model, which replaces the mouse Tardbp gene with the human TARDBP gene through gene editing technology. It can be used to study neurodegenerative diseases such as amyotrophic lateral sclerosis and frontotemporal dementia. The homozygous B6-hTARDBP mice are viable and fertile. In addition, based on the technological innovation of TurboKnockout fusion BAC recombination, Cyagen can also provide popular point mutation disease models based on this model and can provide customized services according to different point mutations to meet the needs of researchers for amyotrophic lateral sclerosis and frontotemporal dementia.

설명:
Rett syndrome (RTT) is an X-linked dominant neurodevelopmental disorder that occurs predominantly in female infants and young children. The incidence is approximately 1 in 10,000–15,000 females. Clinical features include intellectual disability, loss of language function, stereotyped hand movements, and gait abnormalities. Affected children typically have a period of normal development followed by stagnation of head circumference growth at 6–18 months of age, and regression of acquired skills. Overt cognitive and motor impairments develop 1–2 years later. Mutations in the methyl-CpG-binding protein 2 (MECP2) gene account for >90% of RTT cases. MECP2 is a nuclear protein that binds to methylated DNA to regulate gene transcription. MECP2 duplications cause MECP2 duplication syndrome (MDS), while functional deficiency of MECP2 impairs the production of this nuclear protein, leading to central nervous system functional maturation disorders that affect learning and memory functions, resulting in RTT.
Treatment for RTT focuses mainly on gene supplementation therapy based on adeno-associated virus (AAV) vectors. This involves delivering human MECP2 genes via AAV vectors to compensate for the deficiency of MECP2 genes in patients. However, the large size of the MECP2 gene exceeds the delivery capacity of most vectors, and over-expression of the MECP2 gene can also lead to serious neurological diseases. These limitations have hindered the development of this therapy. Therefore, DNA/RNA editing to repair MECP2 gene mutations and restore normal expression of MECP2 protein has received widespread attention. Currently, multiple research groups have used CRISPR-based gene editing technology to repair mutations in the MECP2 gene in induced pluripotent stem cells (iPSCs) or ex vivo patient cells [1-2]. Animal studies are an essential part of preclinical research. RTT therapies based on small nucleic acids, CRISPR gene editing technology, base editors, and RNA editing technology target the human MECP2 gene. Humanized mouse models can help advance gene therapy drug pipelines into clinical stages [3-4].
This strain is a humanized MECP2 gene mouse model that can be used for RTT research. Homozygous B6-hMECP2 mice are viable and fertile. Additionally, based on the independently developed TurboKnockout fusion BAC recombination technology, Cyagen can also generate hot mutation models based on this strain (B6-hMECP2*T158M, Catalog Number: C001569) and provide customized services for specific mutations to meet experimental needs in pharmacology and other RTT-related fields.
