Cancer-testicular Antigens (CTAs) belong to a group of proteins that under normal conditions are strictly expressed in a male's reproductive tissues. However, upon malignisation, they are frequently re-expressed in neoplastic tissues of various origin. A number of studies have shown that different CTAs affect growth, migration and invasion of tumor cells and favor cancer development and metastasis.

The epithelial-mesenchymal transition (EMT) plays a pivotal role in the differentiation of vertebrates and is critically important in tumorigenesis. Using this evolutionarily conserved mechanism, cancer cells become drug-resistant and acquire the ability to escape the cytotoxic effect of anti-cancer drugs. In addition, these cells gain invasive features and increased mobility thereby promoting metastases.

In recent decades, the association between sleep-disordered breathing (SDB) and cardio- and cerebrovascular diseases (including hypertension, coronary heart disease and stroke) has been the focus of interest of both clinicians and researchers. A growing concern is the increasing prevalence of SDB in the general population, which can be partly explained by the rise in obesity prevalence and population aging, as well as by the development of enhanced diagnostic tools and approaches. Because of evidence of adverse long-term effects of SDB on cardiovascular morbidity and overall mortality, systematic screening for SDB should be considered for populations at risk.

Article Synopsis
  • Resveratrol enhances the proliferation and pluripotency of mouse embryonic stem cells (mESCs) by inducing autophagy through the AMPK/Ulk1 pathway and suppressing mTORC1 activity.
  • This process leads to increased expression of key pluripotency markers such as Oct3/4 and Nanog, while allowing for a slower rate of cell proliferation.
  • The findings suggest that the mTOR/Ulk1/AMPK-autophagy network plays a critical role in regulating mESC pluripotency, highlighting the potential for using resveratrol in developing new culture methods and understanding stem cell self-renewal.

The product of human gene, Pirh2, is a RING-finger containing E3 ligase that modifies p53 with ubiquitin residues resulting in its subsequent degradation in proteasomes. Transcription of is regulated by p53 itself thus forming a negative regulatory feedback loop. Functionally, by eliminating p53, Pirh2 facilitates tumorigenesis.
