Involvement of ras p2I in Neurotrophin-induced Response of Sensory, but Not Sympathetic Neurons [PDF]

open access: yes, 1993
Little is known about the signal transduction mechanisms involved in the response to neurotrophins and other neurotrophic factors in neurons, beyond the activation of the tyrosine kinase activity of the neurotrophin receptors belonging to the trk family.

Radiation-Induced DNMT3B Promotes Radioresistance in Nasopharyngeal Carcinoma through Methylation of p53 and p21

open access: yesMolecular Therapy: Oncolytics, 2020
Radiotherapy with or without concurrent chemotherapy is the standard treatment for nasopharyngeal carcinoma (NPC) patients, whose efficacy is limited partly by intrinsic and acquired radioresistance. DNA methyltransferase 3B (DNMT3B) has been reported to

p21 is decreased in polycystic kidney disease and leads to increased epithelial cell cycle progression: roscovitine augments p21 levels. [PDF]

open access: yes, 2007
BackgroundAutosomal dominant polycystic kidney disease (ADPKD) is a common genetic disease with few treatment options other than renal replacement therapy. p21, a cyclin kinase inhibitor which has pleiotropic effects on the cell cycle, in many cases acts

PSMC2 Regulates Cell Cycle Progression Through the p21/Cyclin D1 Pathway and Predicts a Poor Prognosis in Human Hepatocellular Carcinoma

open access: yesFrontiers in Oncology, 2021
Proteasome 26S subunit ATPase 2 (PSMC2) plays a pathogenic role in various cancers. However, its function and molecular mechanism in hepatocellular carcinoma (HCC) remain unknown.

Altered modulation of lamin A/C-HDAC2 interaction and p21 expression during oxidative stress response in HGPS [PDF]

open access: yes, 2018
Defects in stress response are main determinants of cellular senescence and organism aging. In fibroblasts from patients affected by Hutchinson-Gilford progeria, a severe LMNA-linked syndrome associated with bone resorption, cardiovascular disorders, and

The Multifaceted p21 (Cip1/Waf1/CDKN1A) in Cell Differentiation, Migration and Cancer Therapy

open access: yesCancers, 2019
Loss of cell cycle control is characteristic of tumorigenesis. The protein p21 is the founding member of cyclin-dependent kinase inhibitors and an important versatile cell cycle protein.

CDK-Independent and PCNA-Dependent Functions of p21 in DNA Replication

open access: yesGenes, 2020
p21Waf/CIP1 is a small unstructured protein that binds and inactivates cyclin-dependent kinases (CDKs). To this end, p21 levels increase following the activation of the p53 tumor suppressor.

The retinoblastoma protein/p16INK4A pathway but not p53 is disrupted by human papillomavirus in penile squamous cell carcinoma [PDF]

open access: yes, 2011
Aims: The pathogenesis of penile squamous cell carcinoma (PSCC) is not well understood. Human papillomavirus (HPV) may be involved in carcinogenesis, but few studies have compared cell-cycle protein expression in HPV positive and negative cancers.

foxr1 is a novel maternal-effect gene in fish that is required for early embryonic success [PDF]

open access: yesPeerJ, 2018
The family of forkhead box (Fox) transcription factors regulates gonadogenesis and embryogenesis, but the role of foxr1 in reproduction is unknown.

Interplay Between Thiamine and p53/p21 Axes Affects Antiproliferative Action of Cisplatin in Lung Adenocarcinoma Cells by Changing Metabolism of 2-Oxoglutarate/Glutamate

open access: yesFrontiers in Genetics, 2021
Thiamine (vitamin B1) is often deficient in oncopatients, particularly those undergoing chemotherapy. However, interaction between the thiamine deficiency and anticancer action of drugs has not been characterized.
