Thyroid status modulates T lymphoma growth via cell cycle regulatory proteins and angiogenesis [PDF]

open access: yes, 2014
We have shown in vitro that thyroid hormones (THs) regulate the balance between proliferation and apoptosis of T lymphoma cells. The effects of THs on tumor development have been studied, but the results are still controversial.

High-fat diet modifies expression of hepatic cellular senescence gene p16(INK4a) through chromatin modifications in adult male rats

open access: yesGenes & Nutrition, 2018
Background Liver is the crucial organ as a hub for metabolic reactions. p16(INK4a) is a well-established cyclin-dependent kinase (CDK) inhibitor that plays important role in the molecular pathways of senescence, which lead to irreversible cell cycle ...

Cyclin dependent kinase 4 and 6 inhibitors as novel therapeutic agents for targeted treatment of malignant mesothelioma [PDF]

open access: yes, 2017
Malignant Mesothelioma (MM) is a rare and aggressive form of tumour that affects the lining of the internal organs for which current treatments have not been proven to be very effective.

Identification of calpain cleavage sites in the G1 cyclin-dependent kinase inhibitor p19(INK4d) [PDF]

open access: yes, 2006
Calpains are a large family of Ca2+-dependent cysteine proteases that are ubiquitously distributed across most cell types and vertebrate species. Calpains play a role in cell differentiation, apoptosis, cytoskeletal remodeling, signal transduction and ...

Expression analysis of p16 and TOP2A protein biomarkers in cervical cancer lesions and their correlation with clinico-histopathological characteristics in a referral hospital, Tanzania

open access: yesPLoS ONE, 2021
Introduction Biomarkers yield important information for early diagnosis of cervical cancer. However, they are rarely applied for prognosis of cervical cancer in Tanzania, where visual inspection assay with acetic acid or Lugol’s iodine and Pap test are ...

p16( INK4a) positively regulates cyclin D1 and E2F1 through negative control of AUF1.

open access: yesPLoS ONE, 2011
BackgroundThe cyclin-D/CDK4,6/p16(INK4a)/pRB/E2F pathway, a key regulator of the critical G1 to S phase transition of the cell cycle, is universally disrupted in human cancer.

The light and shadow of senescence and inflammation in cardiovascular pathology and regenerative medicine [PDF]

open access: yes, 2017
Recent epidemiologic studies evidence a dramatic increase of cardiovascular diseases, especially associated with the aging of the world population. During aging, the progressive impairment of the cardiovascular functions results from the compromised ...

Differentiation of Human Malignant Melanoma Cells that Escape Apoptosis After Treatment with 9-Nitrocamptothecin In Vitro

open access: yesNeoplasia: An International Journal for Oncology Research, 1999
After in-vitro exposure to 0.05 μmol/L 9-nitrocamptothecin (9NC) for periods of time longer than 5 days, 65% to 80% of the human malignant melanoma SB1 B cells die by apoptosis, whereas the remaining cells are arrested at the G2-phase of the cell cycle ...

eIF4A inhibitors suppress cell-cycle feedback response and acquired resistance to CDK4/6 inhibition in cancer [PDF]

open access: yes, 2019
CDK4/6 inhibitors are FDA-approved drugs for estrogen receptor-positive (ER+) breast cancer and are being evaluated to treat other tumor types, including KRAS-mutant non-small cell lung cancer (NSCLC).
