Obacunone prevents SSR-induced p53 and p21 gene and protein expression modulations in a FT skin model. FT skin models were pretreated for 24 h with obacunone (12.5 uM, 25 uM, and 50 uM) and subjected to 18 J/cm2 of SSR. (A) 24 h after irradiation, p21 and p53 mRNA levels were measured by real-time PCR. Data are expressed as 2− delta deltaCt. (B) p21 and p53 levels were analyzed by Western blotting. Quantification was performed by densitometry and normalized to beta-actin. Data are expressed as 2− delta deltaCt. All data are expressed as a scatter plot with mean +/- standard error of the mean (SEM) of at least two independent experiments (n = 3). Multiple-comparison analysis of variance (ANOVA) was followed by the post hoc Bonferroni test. * p < 0.05 vs. control. # p < 0.05 vs. SSR stimulus. OBA: obacunone.

rhIL-11 and soluble rhIL-11R alpha promotes time-dependent proliferation and senescence in human pulmonary artery endothelial cells (HPAEC) and smooth muscle cells (HPASMC). A HPAECs or B HPASMCs were isolated from control donor subjects and stimulated with rhIL-11 5 ng/ml, rhIL-11R alpha 10 ng/ml or its combination at indicated times. Experiments were done between passages 2–3. Cell proliferation was measured by the BrDU kit at 24 h, 48 h, 72 h and 96 h. Cell senescence was measured after 72 h of cell stimulation using beta-galactosidase histology and P21 expression. Results were expressed as % senescence ( beta-galactosidase blue positive cells) relative to the total number of cells in each field. P21 expression was measured by quantitative PCR (qPCR) as 2− deltaCt and western blot. Data are presented as scatter dot blot with median and interquartile range values (for primary cells, n = 3–4 control subjects performed in triplicate). P-values are based on the Kruskal–Wallis test and Dunn’s post-hoc test for multiple comparison Image collected and cropped by CiteAb from the following open publication (https://pubmed.ncbi.nlm.nih.gov/36376885), licensed under a CC-BY license.

Background: p21/CIP1/CDKN1A

The progression through the cell cycle is regulated by cyclins and their cognate Cdks by promoting cell cycle transitions (1,2,3). This orderly progression can be inhibited by a family of proteins known as CDK inhibitors (CDIs) that bind to cyclin/Cdk complexes and halt cell division (3). p21 (also designated WAF1/Cip1) is one has been shown to inhibit the activity of each member of the cyclin/Cdk family and over expression of this protein inhibits the proliferation of mammalian cells (5). The expression of p21 is inducible by a wide range of stress stimuli and its transcription can be enhanced by p53 (6). Another member of the CDIs is p27 (also known as Kip1), which also sees up regulation in response to antimitogenic stimuli (7). The increased protein expression of p27 results in cellular arrest by binding to cyclin/Cdk complexes, like cyclin D1/Cdk4 (4,8). An additional CDI has been found to bind Cdk4 and Cdk6, p16 (INK4A), and when such complexes are formed, the progression of the cell cycle is halted (9). It has become increasingly clear that p16 is a very important tumor suppressor gene whose frequent loss occurs early in many human cancers. p16 is a major target in carcinogenesis that is rivaled in frequency only by p53 (10).
