Cell-cycle regulation.

چکیده
Cell-division control affects many aspects of development. Caenorhabditis elegans cell-cycle genes have been identified over the past decade, including at least two distinct Cyclin-Dependent Kinases (CDKs), their cyclin partners, positive and negative regulators, and downstream targets. The balance between CDK activation and inactivation determines whether cells proceed through G1 into S phase, and from G2 to M, through regulatory mechanisms that are conserved in more complex eukaryotes. The challenge is to expand our understanding of the basic cell cycle into a comprehensive regulatory network that incorporates environmental factors and coordinates cell division with growth, differentiation and tissue formation during development. Results from several studies indicate a critical role for CKI-1, a CDK inhibitor of the Cip/Kip family, in the temporal control of cell division, potentially acting downstream of heterochronic genes and dauer regulatory pathways.

Effects of berberine on the secretion of cytokines and expression of genes involved in cell cycle regulation in THP-1 monocytic cell line
Objective(s): Current acute myeloid leukemia (AML) therapeutic strategies have irreversible side-effects. Berberine (BBR) is an isoquinoline alkaloid, which has been known as an aryl hydrocarbon receptor (AhR) ligand. AhR is a cytoplasmic receptor, which is involved in the regulation of cellular and immune responses. Here, we investigated the expression profile of genes involved in the cell cyc...
متن کاملUp-regulation of miR-21 decreases chemotherapeutic effect of dendrosomal curcumin in breast cancer cells
Objective(s): Despite the good results of anticancer activities by curcumin, there are some hurdles that limit the use of curcumin as an anticancer agent. Many methods were examined to overcome this defect like the use of the dendrosomal curcumin (DNC). There is increasing evidence that miRNAs play important roles in biological processes. In this study, we focus on the roles of microRNA-21 in t...
متن کاملA novel treatment approach for retinoblastoma by targeting epithelial growth factor receptor expression with a shRNA lentiviral system
Objective(s): Non-invasive treatment options for retinoblastoma (RB), the most common malignant eye tumor among children, are lacking. Epithelial growth factor receptor (EGFR) accelerates cell proliferation, survival, and invasion of many tumors including RB. However, RB treatment by targeting EGFR has not yet been researched. In the current study, we investigated the effect of EGFR down-regula...
متن کاملCabazitaxel antiproliferative mechanism of action in U87MG human glioblastoma cells: a promising cell-cycle phase-specific radiosensitizer
Introduction: One mechanism of cell cycle manipulation and mitotic catastrophe is arrest at G2/M phase of cell cycle. Cabazitaxel, a mitotic inhibitor agent, is a second-generation semisynthetic taxane. An expected anti-neoplastic effect of Cabazitaxel is cell cycle perturbation and alteration of microtubule dynamics. In contrast to other taxane compounds, Cabazitaxel is a poo...
متن کاملFocal Adhesion Kinase (FAK) Involvement in Human Endometrial Remodeling During the Menstrual Cycle
Background: Endometrial remodeling occurs during each menstrual cycle in women. Reports have shown that, in a variety of cell types, processes such as proliferation, signaling complex formation and extra cellular matrix remodeling require a cytoplasmic tyrosine kinase, focal adhesion kinase (FAK). The present study has focused on the expression pattern of FAK in human endometrium during the men...
متن کاملO-10: A Marked Animal-Vegetal Polarity in The Localization of Na+,K+-ATPase Activity and Its Down-Regulation Following Progesterone-Induced Maturation
Background: Polarized cells are key to the process of differentiation. Xenopus oocyte is a polarized cell that has complete blue-print to differentiate 3 germ layers following fertilization, as key determinant molecules (Proteins and RNAs) are asymmetrically localized. The objective of this work was to localize Na+, K+-ATPase activity along animal-vegetal axis of polarized Xenopus oocyte and fo...
