Somatic to iPS Cell Reprogramming

Somatic to iPS Cell Reprogramming

Reprogramming alters the gene expression in somatic cells, transforming them into induced pluripotent stem (iPS) cells over several generations. Scientists can reprogram cells by introducing genes for four transcription factors—Oct4, Sox2, Klf4, and c-Myc (OSKM) by viral or non-viral methods. These factors are also known as Yamanaka factors after Shinya Yamanaka, who first generated iPS cells using mouse skin cells. Yamanaka was awarded the Nobel Prize in Physiology or Medicine in 2012...

Inhibition of Cdk Activity

Inhibition of Cdk Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

Abnormal Proliferation

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

Area of Science:

Urology
Aging Research
Molecular Biology

Background:

The aging prostate significantly impacts male quality of life, affecting sexual and urinary functions, fertility, and disease susceptibility.
Mechanisms driving human prostate aging are not well understood, necessitating further research.

Purpose of the Study:

To elucidate the molecular mechanisms underlying primate prostate aging.
To identify key cellular and molecular changes associated with prostate aging.

Main Methods:

Integration of single-nucleus transcriptomics and histological analyses in primate prostates.
Investigation of the role of GRHL2, CDK19, p53, and p21^Waf1/Cip1 in prostate aging.

Main Results:

Identified epithelial cell senescence, chronic inflammation, and fibrosis as hallmarks of prostate aging.
Demonstrated that GRHL2 downregulation in aging leads to p53 activation and p21^Waf1/Cip1-induced senescence.
Showcased that GRHL2-based gene therapy effectively delays prostate aging and alleviates urinary dysfunction in vivo.

Conclusions:

Elucidated key molecular mechanisms driving primate prostate aging, focusing on the GRHL2-CDK19-p53-p21^Waf1/Cip1 pathway.
Established epithelial cell senescence as a critical factor in prostate aging.
Provided a foundation for developing novel therapeutic strategies targeting prostate aging and related conditions.
