Abstract Cyclin-dependent kinase 4 (CDK4) and CDK6 are critical mediators of cellular
transition into S phase and are important for the initiation, growth and survival of many …

Lysosomes are degradation centers and signaling hubs in cells and play important roles in
cellular homeostasis, development, and aging. Changes in lysosome function are essential …

BACKGROUND Cyclins and cyclin-dependent kinases (CDKs) drive cell division. Of
particular importance to the cancer field are D-cyclins, which activate CDK4 and CDK6. In …

Autophagy is a conserved, self‐degradation system that is critical for maintaining cellular
homeostasis during stress conditions. Dysregulated autophagy has implications in health …

Approximately 75% of all breast cancers express the oestrogen and/or progesterone
receptors. Endocrine therapy is usually effective in these hormone-receptor-positive …

Mutational loss of CDKN2A (encoding p16INK4A) tumor-suppressor function is a key
genetic step that complements activation of KRAS in promoting the development and …

Inhibiting the cell-cycle kinases CDK4 and CDK6 results in significant therapeutic effect in
patients with advanced hormone-positive breast cancer. The efficacy of this strategy is …

PURPOSE A large-panel gene expression analysis was conducted to identify biomarkers
associated with the effectiveness of adding palbociclib to fulvestrant. METHODS The …

Pharmacologic inhibitors of cyclin-dependent kinases 4 and 6 (CDK4/6) have recently
entered the therapeutic armamentarium of clinical oncologists, and show promising activity …

Cellular senescence is defined as irreversible cell cycle arrest caused by various processes
that render viable cells non-functional, hampering normal tissue homeostasis. It has many …
