The ongoing global pandemic of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is marked as one of the most challenging infectious diseases in the history of mankind with affliction of ~29,737,453 confirmed cases globally. Looking at the present scenario where there is a parallel increment in curve with time, there is an utmost emergency to discover a perennial solution to this life-threatening virus which has led the Human race in an unusual state of affair. The entire health care fraternity is engaged in endeavouring an ultimate way out to hit this pandemic but no such research made till now has been approved yet, to have the potential to bring an end to this fatal situation. Although a few possible treatment choices exist at the moment yet the requirement to search for a still better therapeutic option remains persistent. Global laboratories are working day and night in search for an effective vaccine, many are undergoing clinical trials but their commercialization is no less than a year away. The present review highlights the current potential therapies viz., vaccines, immunotherapies, convulsant plasma therapies, corticosteroids, antithrombotic, intravenous immunoglobulins, nocturnal oxygen therapy etc. that may prove beneficial in attenuating the pandemic situation. However, comparison and presentation of collective data on the therapeutic advancements in mitigating the pandemic situation needs further clinical investigations in order to prove boon to mankind.Recent studies have identified neuroinflammation as a significant contributor to the pathological process of traumatic brain injury (TBI) and as a potentially effective target for treatment. LncRNA maternally expressed gene 3 (Meg3) has further been observed to play a critical role in diverse biological processes, including microglial activation and the inflammatory response. However, its target gene and associated signaling pathway require further elucidation. This study found that lipopolysaccharide + ATP upregulated Meg3, promoted microglia activation, Nlrp3/caspase1 activation and inflammation, and markedly reduced miR-7a-5p. Overexpression of miR-7a-5p attenuated Meg3-induced microglial activation, but not Meg3 expression. Bioinformatic analysis and dual-luciferase assays indicated that Meg3 was a direct target of miR-7a-5p that negatively regulates miR-7a-5p expression. Further, we showed that Meg3 acted as a competing endogenous RNA for miR-7a-5p and induced microglial inflammation by regulating nod-like receptor protein 3 (Nlrp3) expression. Our study thus demonstrates Meg3 regulates microglia inflammation by targeting the miR-7a-5p /Nlrp3 pathway.
It remains unclear whether the tumor mutation burden (TMB) or a TMB-related signature could be prognostic indicators in ovarian cancer (OC), as potential correlations with immune infiltrates and immunotherapy responsiveness remains poorly understood.

Data of 941 OC patients were collected from three datasets, including 587, 260, and 94 patients from The Cancer Genome Atlas (TCGA), GSE32062, and the International Cancer Genome Consortium (ICGC), respectively. TMB was calculated and correlations with clinical outcomes, immune infiltrates, and immunotherapy responsiveness were investigated in the TCGA OC cohort. Weighted gene co-expression network analysis was performed to identify TMB-related genes. A TMB-related signature was constructed and validated.

Higher TMB was associated with better survival in the TCGA and ICGC OC cohorts. The high-TMB group had higher CD8+ T-cell infiltration than the low-TMB group. No significant correlation was found between TMB and immunotherapy response. Furthermore, we selected 8 prognostic and TMB-related genes to construct a TMB-related signature that could distinguish between the high- and low-risk patients; its predictive power was validated in the GSE32062 and ICGC datasets. SubMap analysis suggested that patients in the low-risk group might have a better response to anti-PD1 therapy.

We examined the prognostic value of TMB and its potential association with immune cell infiltration and immunotherapy responsiveness in OC. A TMB-related prognostic signature consisting of 8 genes was developed and verified, which might be a promising prognostic signature for the prognosis of OC patients.

Recent studies have revealed the significant roles of immune-related long noncoding RNAs (lncRNAs) in cancer development and progression. The identification of biomarkers that contribute to early detection and risk stratification provides significant benefits for bladder cancer (BC) patients. The current study aimed to determine an immune-related lncRNA signature for predicting the prognosis of BC patients.

Based on The Cancer Genome Atlas (TCGA) database, we identified seven immune-related lncRNAs with prognostic value. The predictive value of the prognostic signature developed from immune-related lncRNAs was assessed by survival and nomogram analyses. Principal component analysis (PCA) was performed to visualize gene expression patterns in the groups defined by the risk score, and the immune composition and purity of the tumor were evaluated by the ESTIMATE algorithm.

Based on the Pearson correlation analysis results, 765 immune-related lncRNAs were filtered (|R| > 0.4, P<0.001), and seven immune-related lncRNAs (Z84484.1, AC009120.2, AL450384.2, AC024060.1, TNFRSF14-AS1, AL354919.2, OCIAD1-AS1) with prognostic value were finally identified. Patients in the low-risk group had a better prognosis than those in the high-risk group. Multivariate Cox regression analysis showed that the signature was an independent prognostic factor. find more A prognostic nomogram with clinical features and the signature of seven immune-related lncRNAs was also constructed. According to the PCA and ESTIMATE algorithm results, we found different immune statuses in the low-and high-risk groups.

Our study shows that the signature of seven immune-related lncRNAs can be used as a prognostic marker for BC.
