Induction of G2M Cell Cycle Arrest and Biology Diagrams The p53 protein is the product of mutations in the p53 gene. It plays an anti-proliferative effect in different types of stress responses, including cell cycle arrest and apoptosis. For example, when cells are damaged or cell proliferation is abnormal, the p53 gene is activated, leading to cell cycle arrest and even cell apoptosis . In tumor
We therefore investigated whether therapeutically targeting cell cycle control pathways that converge on the G 1 /S restriction point could synergise with cytotoxic chemotherapy, potentially circumventing chemoresistance. The addition of MDM2 inhibitor, nutlin-3a with AraC/Dox achieved striking synergism in TP53-competent cell lines in reducing viability and promoting apoptosis.
Development of chemotherapy with cell cycle inhibitors for adult and ... Biology Diagrams
In conclusion, our data identifies cell cycle dysregulation as a clinically relevant mediator of chemoresistance in AML, highlights therapeutic pitfalls in inducing cell cycle arrest and finally
In preclinical studies, it was reported to induce cell cycle arrest and tumor growth inhibition in a majority of solid tumor cell lines especially those of B-cell origin and xenografts 88. phase II clinical trials were completed with flavopiridol in chronic lymphocytic leukemia 89, endometrial adenocarcinoma 90, multiple myeloma 91, and
Targeting Control of Cell Cycle Enhances the Activity of Conventional ... Biology Diagrams
Generating excessive levels of DNA damage, through either radiotherapy or chemotherapy, The cell-cycle arrest and apoptotic functions of p53 in tumor initiation and progression.
The best example demonstrating the relevance of the cell cycle in combination chemotherapy includes those combinations that involve taxanes, the prototypical class of cell cycle-specific chemotherapeutic agents. The cell cycle arrest in G 2 attributable to cisplatin treatment caused a relative insensitivity to subsequent paclitaxel Cell cycle arrest: A breakthrough in the supportive care of older cancer patients J Am Geriatr Soc. 2023 Apr 10. doi: 10.1111/jgs.18350. Background: Age is a major risk factor for the acute and chronic complications of cancer chemotherapy. The current approach to the prevention of these complications is reactive and involves the reduction Keywords: cell cycle arrest, DNA damage, chemotherapy. Introduction. The normal cell cycle consists of complex pathways that regulate the duplication of all molecules and organelles and their separation into two identical daughter cells. This progresses through four phases: G1 (gap), S (synthesis), G2 (gap) and M (mitosis) and is coordinated by
