Concurrent mutations, in genes such as CDKN2B or RB1, were associated with worse clinical outcome in lung adenocarcinoma patients with EGFR active mutations.

Mutational screening of germline RB1 gene in Vietnamese patients with retinoblastoma reveals three novel mutations.
-
Analyses with phospho-defective and phospho-mimetic mutants of FoxM1b identified a critical role of the Plk1 phosphorylation sites in regulating the binding of FoxM1b to Rb and DNMT3b.
-
The accumulation of sequence variations in RB1 gene might influence Greek patients' susceptibility towards the progression of cervical neoplasia.
-
vitiligo lesions exhibited dysregulated SUMOylation and deSUMOylation in keratinocytes, dysregulation of the cell cycle progression was observed in SUMO1 knockdown HaCaT cells and the deSUMOylation of Rb in keratinocytes may serve an important role in the development of vitiligo.
-
The Rb1 tumor suppressor gene modifies telomeric chromatin architecture by regulating TERRA expression.
-
These findings demonstrate that developmental stage-specific as well as species- and cell type-specific features sensitize to RB1 inactivation and reveal the human cone precursors' capacity to model retinoblastoma initiation, proliferation, premalignant arrest, and tumor growth.
-
Low pRB expression is associated with mouth Cancer.
-
Control of the Restriction Point by Rb and p21.
-
PPM1B plays a negative role in the activation of the p38-RB1-E2F1 pathway and that targeting PPM1B could be useful in certain types of cancer by stimulating chemotherapy-induced cell death.
-
results showed that a) alterations of the p53 and Rb pathways are associated with high proliferation of tumor cells in BUC and b) high expression of cell-cycle proteins is associated with adverse histopathological parameters of these tumors
-
he present result indicated that vascular smooth proliferation is regulated by activation of the NF-kappaB p65/miR17/RB pathway. As NF-kappaB p65 signalling is activated in and is a master regulator of the inflammatory response, the present findings may provide a mechanism for the excessive proliferation of VSMCs under inflammation during vascular disorders and may identify novel targets for the treatment of vascular d...

Reduced RB expression in medullary thyroid cancer is associated with decreased patient survival in univariate and multivariable analyses, independent from patient age at surgery or advanced TNM stage.
-
According to immunohistochemistry and immunoblot analysis, the expression levels of cyclin D1, cyclin E, pRb, and Ki67 in psoriasis lesions decreased after treatment and were similar with those in the normal group
-
Data indicate that nuclear envelope rupture in cancer cells is likely due to loss of either the Rb or the p53 pathway.
-
Altered pRb is frequently expressed in gastric carcinoma, inversely correlates with tumor invasion and tumor stage suggesting an early event in gastric carcinogenesis.
-
results define a network of E2F target genes as susceptible to the regulatory influence of H1.2, where H1.2 augments global association of pRb with chromatin, enhances transcriptional repression by pRb, and facilitates pRb-dependent cell-cycle arrest
-
The increased expression of miR-503-5p significantly reduced the expressions of E2F transcription factor 3 (E2F3) mRNA and retinoblastoma protein (Rb)/E2F signaling pathway mRNA in bladder cancer cells.
-
Loss of Rb immunolabeling and KRAS mutation are promising molecular markers of the therapeutic response to platinum-based chemotherapy for pancreatic neuroendocrine neoplasm grade-3 (PanNEN-G3), and Rb for neuroendocrine tumor with G3 (NET-G3).
-
We recommend intensive ocular screening for patients with germline RB1 mutations for retinoblastoma as well as neuroimaging for pineoblastoma surveillance. There is an approximately 20% risk of developing second primary cancers among individuals with hereditary RB, higher among those who received radiotherapy for their primary RB tumors
