Molecular Signaling in Tumorigenesis of Gastric Cancer
Gastric cancer (GC) is regarded as the fifth most common cancer and the third cause of cancer-related deaths worldwide. Mechanism of GC pathogenesis is still unclear and relies on multiple factors, including environmental and genetic characteristics. One of the most important environmental factors of GC occurrence is infection with Helicobacter pylori that is classified as class one carcinogens...
متن کاملThe RSK factors of activating the Ras/MAPK signaling cascade.
The p90 ribosomal S6 kinase (RSK) constitute a family of serine/threonine kinases activated downstream of the Ras/mitogen-activated protein kinase (MAPK) pathway. In mammals, four RSK genes have been identified (RSK1, RSK2, RSK3 and RSK4), and RSK orthologues have also been described in D. melanogaster and C. elegans, but not in yeast or plants. The RSK isoforms are composed of two distinct and...
متن کاملIntegrins promote cytokinesis through the RSK signaling axis.
Cytokinesis is the final stage in cell division. Although integrins can regulate cytokinesis, the mechanisms involved are not fully understood. In this study, we demonstrate that integrin-regulated ERK (extracellular signal-related kinase) and RSK (p90 ribosomal S6 kinase) signaling promotes successful cytokinesis. Inhibiting the activation of ERK and RSK in CHO cells by a mutation in the integ...
متن کاملSteroid Hormone Intervenes in the Endometrial Tumorigenesis of Pten Ablation
BACKGROUND Endometrial cancer, the most common gynecological cancer, is closely associated with endometrial hyperplasia, unopposed estrogen exposure, and genetic alterations. Phosphatase and tensin homologue (PTEN) is a tumor suppressor genes completely lost or mutated in >50% of primary endometrioid endometrial cancers. Estrogen-dependent endometrioid carcinoma is the most common type of endom...
متن کاملKrasG12D upregulates Notch signaling to induce gallbladder tumorigenesis in mice
Background Kras mutations and increased Notch activation occur frequently in gallbladder cancer. However, their roles in gallbladder carcinogenesis have not been defined. This study was aimed at determining whether expression of mutant Kras was sufficient to induce gallbladder carcinoma and whether Notch deregulation played a role in this context. Methods We determined Cre recombination activ...
