While DNA gets damaged, it takes part in the neoplastic apoptotic mechanism. In this study, we evaluated the structure of Rho-related GTP-binding protein RhoB due to the unavailability of 3D structure in the protein data bank database. Results: The expected pI value of RhoB was 5.10 (acidic). The target–template alignment was computed using the GMQE value meanwhile 6hxu.1.A from Homo sapiens was selected as the template structure. The Swiss model was exploited to complete the model construction task. The structural compatibility and stability were revealed after a 100ns molecular dynamics simulation using GROMACA employing the OPLS-AA force field. Based on their fluctuating activity and their location between 100 and 110 and 140 and 150, PCA analysis discovered relevant residues. Conclusion: By providing an insight into the biophysical phenomenon of Rho-related GTP-binding protein RhoB inhibitors, this study will assist future investigations addressing the relationship between gene mutation and abnormalities produced by protein Rho-related GTP-binding protein RhoB in apoptotic events.","PeriodicalId":73645,"journal":{"name":"Journal of cellular signaling","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135278556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hereby, we hypothesize that Coronavirus disease 2019 (COVID-19) may contribute to lung cancer progression by increasing extracellular adenosine triphosphate (ATP) levels and hyperactivating the purinergic P2X purinoceptor 7 receptor (P2X7R). Hyperactivation of P2X7R by increased extracellular ATP may stimulate multiple signaling pathways and factors such as NLRP3 inflammasome; as a result, interleukin (IL)-1β, and IL-18 pro-inflammatory cytokines are released, JNK, Rho kinase, HMGB1-RAGE, PI3K/AKT, hypoxia-inducible factor-1 alpha (HIF-1α), and ERK. NLRP3 activation may play a pivotal role in fatal cytokine storm in critically ill patients with COVID-19 and tumor progression in patients with lung cancer. Consequently, inhibiting these signaling pathways may deviate immune responses toward anti-tumoral responses, and suppress lung cancer progression and cytokine storms. Therefore, targeting P2X7R by means of oxidized ATP and anti-P2X7 monoclonal antibodies may provide promising therapeutic approaches to prevent lung cancer progression in COVID-19 patients; however, no clinical trials have yet been conducted, and their clinical efficacy remains to be elucidated.","PeriodicalId":73645,"journal":{"name":"Journal of cellular signaling","volume":"69 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90714182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Following surgery, radiation, and chemotherapy, patients who develop progressive disease have few treatment options. An analysis of the dysregulated protein network caused by MYCN amplification suggested co-targeting PLK1, AURKA, CKS1, AKT, MTOR, and USP7 would be useful to take advantage of synthetic lethal vulnerabilities while overcoming redundancies and resistance mechanisms that stabilize N-Myc by preventing its proteasome degradation. Naturopathic compounds, (genistein, tanshinone, resveratrol, betulinic acid) and fluoxetine were re-purposed to target the complex protein network in a patient with MYCN -amplified and PTEN -deficient multifocal, relapsed anaplastic ependymoma following standard therapy. The patient achieved a clinically meaningful and durable response for 6 months prior to developing disease progression characterized by chromosome 11q ( YAP1, BIRC2/3 ) amplification. The experience suggests molecularly-informed integration of naturopathic compounds can have utility for disease control and survival. The success, although anecdotal, suggests that the previous failure of single agent strategies could be overcome with a network targeting approach that simultaneously precipitates cell cycle arrest, rescues FBXW7 ubiquitination, and enhances oxidative stress. As such, MYCN may no longer be strictly unactionable but appears amenable to co-targeting key nodes in its self-sustaining disease network.","PeriodicalId":73645,"journal":{"name":"Journal of cellular signaling","volume":"201 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74888730","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
