Castration‐resistant prostate cancer cells are addicted to the high activity of cyclin‐dependent kinase 2

Molecular Oncology, EarlyView.
We show that emergence of castration‐resistant prostate (CRPC) is associated with significant upregulation of cyclins that positively regulate cyclin‐dependent kinase 2 (CDK2) and concomitant downregulation of CDK4 cyclins. This renders CRPC cells dependent on the high activity of CDK2, and CDK2 inhibitors synergistically sensitize CRPC cells to both ...

A DNA G‐Quadruplex‐Targeting Ligand Suppresses c‐MYC Expression: Implications for Gemcitabine‑Resistant Pancreatic Cancer

Angewandte Chemie, EarlyView.
PQB‐4, a fluorescent small‐molecule ligand that targets c‐MYC DNA G‐quadruplexes (G4s), showed marked synergy with gemcitabine in resistant PANC‐1 cells (CI = 0.027). In vivo, the ligand reduced tumor weight by 44% in a PANC‐1 xenograft model. These results highlight the therapeutic potential of c‐MYC DNA G4‐targeting ligands for treating gemcitabine ...

Genetic background and climatic droplet keratopathy incidence in a Mapuche population from Argentina. [PDF]

PLoS ONE, 2013
PURPOSE:To determine whether the incidence of and susceptibility to climatic droplet keratopathy (CDK), an acquired, often bilateral degenerative corneal disease, is influenced by the genetic background of the individuals who exhibit the disorder ...

Mechanisms and therapeutic opportunities of the ribotoxic stress response in cancer

Molecular Oncology, EarlyView.
Cancer cells' high translational demand creates opportunities to therapeutically target ribosome function. Ribosome stalling and collisions activate ZAKα and the ribotoxic stress response (RSR), which can trigger rapid, p53‐independent apoptosis in cancer.

Evaluating the Effects of Molecular Dynamic And Docking of Abemaciclib, Hymenialdisine, and Indirubin on CDK-2 Inhibition by Simulation Study

Journal of Ardabil University of Medical Sciences, 2022
Background & objectives: Cyclin-dependent kinase 2 (CDK-2) is a serine/threonine protein kinase with regulatory activity in the cell cycle. Inhibitors of this protein are the treatment of choice for a variety of cancers by stopping the cell cycle.

Extracellular matrix remodeling and immune reprogramming drive residual tumor progression of liver cancer after incomplete microwave ablation

Molecular Oncology, EarlyView.
Incomplete microwave ablation (iMWA) of liver cancer triggers a biphasic progression in residual tumors. At Day 3, the microenvironment is characterized by acute inflammatory responses and extracellular matrix (ECM) remodeling. By Day 14, a profound shift occurs toward oncogenic signal transduction and immunosuppression, marked by macrophage ...

Ubiquitin ligase activity inhibits Cdk5 to control axon termination.

PLoS Genetics, 2022
The Cdk5 kinase plays prominent roles in nervous system development, plasticity, behavior and disease. It also has important, non-neuronal functions in cancer, the immune system and insulin secretion.

Both p16 and p21 Families of Cyclin-dependent Kinase (CDK) Inhibitors Block the Phosphorylation of Cyclin-dependent Kinases by the CDK-activating Kinase [PDF]

, 1995
Phosphorylation of cyclin-dependent kinases (CDKs) by the CDK-activating kinase is required for the activation of CDK enzymes. Members of two families of CDK inhibitors, p16/p18 and p21/p27, become physically associated with and inhibit the activity of ...

ATZ‐1 promotes DNA replication efficiency to maintain normal meiotic function

FEBS Open Bio, EarlyView.
Absence of ATZ‐1 interferes with meiotic DNA replication and cell cycle function via CHK‐1. This causes downstream defects associated with DNA damage and genomic integrity. Taken together, this study suggests that ATZ‐1 influences DNA replication efficiency and cell cycle function to maintain normal meiotic function.

Caenorhabditis elegans cyclin D/CDK4 and cyclin E/CDK2 induce distinct cell cycle re-entry programs in differentiated muscle cells. [PDF]

PLoS Genetics, 2011
Cell proliferation and differentiation are regulated in a highly coordinated and inverse manner during development and tissue homeostasis. Terminal differentiation usually coincides with cell cycle exit and is thought to engage stable transcriptional ...
