Immunosenescence promotes cancer development: from mechanisms to treatment strategies.

The body's innate immune system plays a pivotal role in identifying and eliminating cancer cells. However, as the immune system ages, its functionality can deteriorate, becoming dysfunctional, inefficient, or even inactive-a condition referred to as immunosenescence. This decline significantly increases the risk of malignancies.

PDCD11 Stabilizes C-MYC Oncoprotein by Hindering C-MYC-SKP2 Negative Feedback Loop to Facilitate Progression of p53-Mutant Breast and Colon Malignancies.

C-MYC is a proto-oncoprotein whose dysregulation triggers tumorigenesis and tumor progression in ≈70% of cancer cases. It is presently demonstrated that aberrantly upregulated MYC is caused by the overexpressed and "extra-nucleolar" PDCD11 in p53-mutant breast and colon cancer cells, which is highly correlated to tumor progression, metastasis, and recurrence. In the nucleoplasm, PDCD11 binds to the TAD of C-MYC to prevent SKP2, a transcriptional target of C-MYC as well as one of the major E3 ligase components targeting C-MYC, from interacting with and ubiquitinating C-MYC in feedback.

Deficiency in Yeast Induces Endoplasmic Reticulum Stress and Shortens the Chronological Lifespan.

Yeast was initially identified as a homolog of human TIMM8A/DDP1, which is associated with human deafness-dystonia syndrome. Tim8p is located in the mitochondrial intermembrane space and forms a hetero-oligomeric complex with Tim13p to facilitate protein transport through the TIM22 translocation system. Previous research has indicated that is not essential for yeast survival but does affect the import of Tim23p in the absence of the Tim8-Tim13 complex.
