Revealing A-Raf functions through its interactome

Publication date: August 2018Source: Biochimica et Biophysica Acta (BBA) - Proteins and Proteomics, Volume 1866, Issue 8Author(s): Xin-Yu Zhang, Hui Guo, Bing Han, Xu-Min Zhang, Ying Huang, Yang Yang, Ying Liu, Xiao-Xi Guo, Qian Hao, Su An, Tian-Rui XuAbstractA-Raf is a member of the Raf kinase family. Unlike B-Raf and C-Raf, the functions of A-Raf remain obscure. To gain more insight into the biological functions of A-Raf, we investigated the A-Raf interactome using proteomics. We found 132 proteins that interact with A-Raf and confirmed the interaction of 12 of these proteins with A-Raf by western blotting. Our data suggested that A-Raf regulates apoptosis, RNA catabolism, GTPase activity, and cell adhesion by interacting with proteins located in different cellular compartments. We identified all ten hallmarks of cancer in these interacting proteins, suggesting that A-Raf is involved in carcinogenesis. Our results also indicated that A-Raf may play a role in different diseases and signaling pathways. These findings have identified potential regulators of A-Raf and provide a systemic insight into its biological functions.

ConclusionThere is need to improve both the knowledge base and comfort level of pediatricians in counseling their patients during vaccine recommendations. Otolaryngologists have a critical role in providing education to physicians, trainees, and the general public in the effort to combat the epidemic of HPV-associated head and neck cancer.

In conclusion, the spectrum of autoimmune reactions induced by immune-checkpoint inhibitors should be restricted in the near future to only these specific favorable autoimmune mechanisms. In this way, the unnecessary autoimmune reactions/autoaggressions could be avoided (a better quality of life), and treatment specificity and efficiency should increase (a higher response rate for melanoma therapy).

Long noncoding RNA X-inactive specific transcript (XIST) was confirmed to participate in the development of many cancers. However, the function of XIST in malignant melanoma (MM) remained largely unknown. In the current study, we found that the XIST expression level was upregulated in MM tissues and cell lines. In addition, the growth rate of MM cells transfected with silencing XIST was significantly decreased compared with that with silencing normal control. XIST knockdown inhibited proliferation and migration in MM cells and increased the oxaliplatin sensitivity of oxaliplatin-resistant MM cells. Bioinformatics analysis ...

The recently developed therapeutic strategies have led to unprecedented improvements in the control of metastatic melanoma and in the survival of specific subgroups of patients. However, drug resistance, low response rates, and undesired side effects make these treatments not suitable or tolerable for all the patients, and chemotherapeutic treatments appear still indispensable, at least for subgroups of patients. New combinatory strategies are also under investigation as tailored treatments or salvage therapies, including combined treatments of immunotherapy with conventional chemotherapy. On this basis, and in considerati...

Patients diagnosed with metastatic melanoma have varied clinical courses, even in patients with similar disease characteristics. We examine the impact of initial stage of melanoma diagnosis, BRAF status of primary melanoma, and receiving adjuvant therapy on postmetastatic overall survival (pmOS). We studied melanoma patients presenting to Perlmutter Cancer Center at New York University and prospectively enrolled in New York University melanoma biospecimen database and followed up on protocol-driven schedule. Patients were stratified by stage at initial melanoma diagnosis as per AJCC 7th ed. guidelines. pmOS was determined ...

The gut microbiota impacts response to immunotherapy in cancer patients. We sought to evaluate the role of physiologic colonic fluorine-18-fluorodeoxyglucose (18F-FDG) uptake, a test that was recently shown to reflect colonic bacterial load, as a possible predictor for response to immunotherapy. We carried out a retrospective study in metastatic melanoma patients who received the immune checkpoint inhibitor ipilimumab as first-line therapy. All patients underwent an 18F-FDG PET scan before treatment initiation. The primary outcome was defined as response to treatment according to the RECIST criteria. Regions of interest we...
