Project description:The aim of this study is to estimate gene expression variations involved in glucose meatbolism in HepG2 cell line after cell cycle(G1 to S phase) inhibition by using drug(PD-0332991) or CDK4-6-knock down. We hypothesized that transition of glycolytic gene expression might indicates the effect of PD-0332991 drug treatment in Hepatocellular carcinoma cells.

Project description:PD-0332991 is a small molecule inhibitor for Cdk4 and Cdk6. It exerted growth inhibitory effects on PDAC cell lines (AsPC-1 and COLO-357). Microarray analysis was used to characterize the changes in gene expression profiles of AsPC-1 and COLO-357 upon PD-0332991 incubation AsPC-1 and COLO-357 cells were treated in the absence or presence of 5 µM PD-0332991 for 24 h and 72 h. Each expreimental condition had biological triplicates. Twenty-four samples were analyzed in total.

Project description:Cyclin D3 is critical hematopoiesis and loss of cyclin D3 leads to resistance to transformation of bone marrow progenitors by Notch1-IC. We used a small molecule targeting cyclin D3:CDK4/6 activity to study whether its inhibition is an effective therapeutic strategy. We analyzed T-ALL lines in vitro with PD-0332991 or vehicle control to determine genes affected by the drug. CEM, Jurkat, DND41, and CUTL-1 cell lines were treated with 1 uM PD-0332991 or DMSO for 15 hours prior to RNA extraction and hybridization to Human Genome U133 Plus 2.0 Affymetrix arrays.

Project description:By selective and reversible inhibition of CDK4/CDK6, we have developed a strategy to both inhibit proliferation and enhance cytotoxic killing of cancer cells. Induction of prolonged early-G1 arrest (pG1) by CDK4/CDK6 inhibition halts gene expression in early-G1 and prevents expression of genes programmed for other cell cycle phases. S-phase synchronization upon removal of the early-G1 block (pG1-S) fails to completely restore scheduled gene expression. Consequently, coordinate loss of IRF4 and gain of Bim and Noxa expression sensitize myeloma tumor cells to bortezomib-induced apoptosis in pG1 and more profoundly in pG1-S in vitro. Induction of pG1 and pG1-S by CDK4/CDK6 inhibition augments tumor-specific bortezomib killing in myeloma xenografts. Inhibition of CDK4/CDK6 in combination therapy thus represents a novel mechanism-based cancer therapy. PD 0332991 (PD) is the only known specific and reversible CDK4/CDK6 inhibitor. Gene expression was measured in myeloma MM1.S cells treated with PD (0.25 uM) in triplicate for 12, 24 or 36 h, or in cells released from G1, induced by 24hPD, for 4 or 18 h.

Project description:Purpose: to identify the impact of cdk4 inhibition on genes and pathways involved in age-associated liver disorders using next generation sequencing on young and control- or PD0332991-treated aged mice. Methods: RNA was isolated from livers of young (2 month old) and old (20-22 month old) C57Bl6 mice. Old mice were either either control-aged mice or PD-0332991 treated aged mice (450mg/dk for 2 weeks). The three conditions were represented in triplicate. Raw reads passing quality filtration were aligned to the mm10 mouse genome using UCSC annotations by pseudoalignment in Kallisto. All reasonably expressed transcripts were submitted for statistical analysis to identify age-altered transcripts corrected by cdk4 inhibition. Results: We mapped a minimum of 20 million reads per sample, which corresponded to a total of 25,240 transcripts. Of these, 12,551 were considered reasonably expressed and were included in analysis comparing control-aged v young and PD0332991-treated-aged v young. Conclusion: Inhibition of cdk4 in ages wildtype mice by cdk4 inhibitor PD-0332991 reduces CEBPa-p300 and reduced aged-related alterations of hepatic structure and function.

Project description:PD-0332991 is a selective inhibitor of the CDK4/6 kinases with the ability to block retinoblastoma (Rb) phosphorylation in the low nanomolar range. Here we investigate the role of CDK4/6 inhibition in human ovarian cancer. We examined the effects of PD-0332991 on proliferation, cell-cycle, apoptosis, and Rb phosphorylation using a panel of 40 established human ovarian cancer cell lines. Molecular markers for response prediction, including p16 and Rb, were studied using gene expression profiling, Western blot, and arrayCGH. Multiple drug effect analysis was used to study interactions with chemotherapeutic drugs. Expression of p16 and Rb was studied using immunohistochemistry in a large clinical cohort ovarian cancer patients. Concentration-dependent anti-proliferative effects of PD-0332991were seen in all ovarian cancer cell lines, but varied significantly between individual lines. Rb proficient cell lines with low p16 expression were most responsive to CDK4/6 inhibition. Copy number variations of CDKN2A, Rb, CCNE1, and CCND1 were associated with response to PD-0332991. CDK4/6 inhibition induced G0/G1 cell cycle arrest, blocked Rb phosphorylation in a concentration and time dependent manner, and enhanced the effects of chemotherapy. Rb proficiency with low p16 expression was seen in 97/262 (37%) of ovarian cancer patients and associated with adverse clinical outcome (progression free survival, adjusted relative risk 1.49, 95%CI 0.99-2.22, p =0.054). PD-0332991 shows promising biologic activity in ovarian cancer cell lines. Assessment of Rb and p16 expression may help select patients most likely to benefit from CDK4/6 inhibition in ovarian cancer. Gene expression of 40 individual ovarian cell lines relative to an ovarian cell line reference mix containing equal amounts of 41 ovarian cell lines (including OCC-1 which was later identified as originating from mouse). The expression data was correllated with cell line growth response to CDK 4/6 inhibitor PD-0332991 to identify genes associated with drug sensitivity and resistance.
