Map3k7cl-KO Mouse

Map3k7cl, also known as MAP3K7-interacting protein 1 (MIP1), is a kinase gene. It is involved in various biological processes, and its dysregulation has been linked to multiple diseases [1-10]. Although its exact function and associated pathways are still being explored, its role in diseases suggests it is biologically important, and genetic models could be valuable for further study.

In a case of dermatofibrosarcoma protuberans with fibrosarcomatous transformation, a novel MAP3K7CL-ERG fusion was reported, indicating its potential role in this cancer transformation [1]. In pediatric sepsis, MAP3K7CL was downregulated and had a protective role, suggesting its involvement in immune response regulation in sepsis [2]. DNA methylation analysis in Tibetan elite alpinists showed that some differentially methylated CpGs were in the MAP3K7CL gene, indicating its possible role in response to extreme hypoxia [3]. In a canine model of dermatomyositis, a polymorphism in MAP3K7CL was associated with the disease, providing evidence for an epistatic foundation for this disease [4]. In congenital heart defects, CNVs in the MAP3K7CL locus were identified, and the gene was highly expressed in human and mouse embryo hearts, suggesting its role in heart development [5]. In heart failure, a genome-wide association analysis of all-cause HF identified MAP3K7CL as a locus linked to upstream HF risk factors [6]. In a Taiwanese population with chronic obstructive pulmonary disease, MAP3K7CL was identified as a prominent susceptibility locus [7]. In human vascular smooth muscle cells stimulated by high phosphorus, MAP3K7CL mRNA expression was lower in the high-phosphorus group, suggesting its possible role in vascular calcification [8]. In non-small cell lung cancer, MAP3K7CL was downregulated in tumor-educated leukocytes and was part of a four-gene panel with diagnostic potential [9]. In neurodegenerative diseases, MAP3K7CL was one of the mRNAs found in common among extracellular vesicles of patients with ALS, FTD, and PD [10].

In conclusion, Map3k7cl is involved in diverse biological processes and disease conditions, including cancer, sepsis, hypoxia response, muscle and heart-related diseases, and neurodegenerative diseases. The findings from various studies, though not directly from KO/CKO mouse models in the provided references, suggest its significance in understanding the molecular mechanisms underlying these diseases, potentially paving the way for future research and therapeutic strategies.
