背景情况:
- 细胞衰老有助于代谢功能障碍相关的脂肪性肝病 (MASLD) 的发病.
- 老化药物在缓解MASLD诱导的肝损伤及其对男性生育能力的影响中的有效性尚未得到充分证实.
研究的目的:
- 调查老化药物对肝损伤和男性生殖功能障碍的保护作用,在小鼠模型中进行MASLD.
- 为了确定老化药是否可以逆转已经确定的肝损伤,衰老和炎症在MASLD.
主要方法:
- 雄性小鼠被食了缺乏胆的西方饮食 (WD),以诱导MASLD.
- 小鼠接受了老化疗法 (达沙替尼 + 奎尔塞丁或菲塞丁) 或车载控制.

In-vitro Mutagenesis
13.9K
To learn more about the function of a gene, researchers can observe what happens when the gene is inactivated or “knocked out,” by creating genetically engineered knockout animals. Knockout mice have been particularly useful as models for human diseases such as cancer, Parkinson’s disease, and diabetes.

Infertility in Males
256
Male infertility affects millions of couples worldwide, arising from various factors that impact different stages of the reproductive process. An endocrine imbalance resulting from conditions like hypogonadism, Klinefelter syndrome, or pituitary disorders can disrupt hormone levels and reduce sperm production. Testicular defects, such as tumors, cryptorchidism, atrophic testes, abnormal sperm morphology, and low sperm count or motility, may arise due to genetic factors, structural...
