Overview of Gene Research
Mir195a is a microRNA that plays crucial roles in multiple biological processes. It is involved in regulating cell proliferation, apoptosis, and metabolism, and is associated with pathways like the Hippo signaling pathway. MicroRNAs like Mir195a are important for maintaining normal cellular functions and their dysregulation can lead to various pathological conditions [1,4].
In miR-195a KO mice, cognitive impairment and reduced dendritic spine density were observed, indicating its role in age-associated cognitive functions. Sema3D was identified as a direct target of miR-195a, and its age-dependent increase in rodent brains suggested a possible contribution to age-associated neurodegeneration [2].
In mice prenatally exposed to vinclozolin, increased miR-195a levels in the offspring's penises, testes, uteri, and ovaries were found. This led to activation of the Hippo pathway, down-regulation of the androgen receptor in penises, and ultimately caused penile, testicular, uterine, and ovarian damage and malformations [1,4].
In Dicer-deficient macrophages, restoring miR-195a expression could rescue mitochondrial fatty acid oxidative metabolism, highlighting its role in macrophage activation and atherosclerosis prevention [3]. Also, miR-195a inhibits adipocyte differentiation by targeting Zfp423, suggesting its involvement in obesity and metabolic diseases [5].
In intervertebral disk degeneration, silencing of lncRNA NEAT1 upregulates miR-195a to attenuate the process via the BAX/BAK pathway [6]. Benzothiazole-based conjugates affect miR-195a expression, causing cell cycle arrest and apoptosis in hepatocellular carcinoma cells [7].
In conclusion, Mir195a is essential in various biological processes and disease conditions. Gene knockout mouse models have been instrumental in revealing its functions in age-associated cognitive impairment, reproductive organ development, macrophage-related atherosclerosis, adipocyte differentiation, intervertebral disk degeneration, and hepatocellular carcinoma. Understanding Mir195a provides insights into disease mechanisms and potential therapeutic targets.
