Alternative splicing (AS) is a crucial mechanism to regulate gene expression and protein complexity. RNA-binding proteins (RBPs) play an important role in regulating abnormal alternative splicing in cancers. However, few resources are available to identify specific RBPs responsible for regulating individual AS event.

Clear cell renal cell carcinoma (ccRCC) is a primary kidney cancer with high aggressive phenotype and extremely poor prognosis. Accumulating evidence suggests that circular RNAs (circRNAs) play pivotal roles in the occurrence and development of various human cancers. However, the expression, clinical significance and regulatory role of circRNAs in ccRCC remain largely unclear.

Article Synopsis
  • Simnotrelvir, an oral protease inhibitor, showed promise in treating mild-to-moderate COVID-19 in a phase 2-3 clinical trial.
  • In the study, patients received either simnotrelvir plus ritonavir or a placebo, with results indicating that those on the drug experienced faster resolution of symptoms compared to the placebo group.
  • Although more adverse events were reported in the simnotrelvir group, most were mild to moderate, suggesting that the treatment is generally safe.

The relationship between serum uric acid and lung function has been controversial. This study aims to determine whether there is an independent relationship between serum uric acid and lung function in the National Health and Nutrition Examination Survey (NHANES) from 2007 to 2012. Serum uric acid was considered the exposure variable, and lung function (FEV1 and FVC) was the outcome variable.

Background: Alternative splicing events (ASEs) are vital causes of tumor heterogeneity in genitourinary tumors and many other cancers. However, the clinicopathological relevance of ASEs in cancers has not yet been comprehensively characterized.

Methods: By analyzing splicing data from the TCGA SpliceSeq database and phenotype data for all TCGA samples from the UCSC Xena database, we identified differential clinical feature-related ASEs in 33 tumors.

Bladder cancer (BC) is a complex disease affecting the urinary system and is regulated by several carcinogenic factors. Viral infection is one such factor that has attracted extensive attention in BC. Human papillomavirus (HPV) is the most common sexually transmitted infection, and although multiple researchers have explored the role of HPV in BC, a consensus has not yet been reached.

Background: Epithelial-mesenchymal transition (EMT) is associated with early recurrence and a poor prognosis in clear cell renal cell carcinoma (ccRCC). Studies have shown that EMT-related genes play an important regulatory role in tumor invasion, metastasis, and drug resistance, but the biological functions of EMT-related genes in ccRCC have not been specifically described.

Methods: The mRNA and clinicopathological data of 532 ccRCC and 72 normal samples were downloaded from The Cancer Genome Atlas as a training set.

Article Synopsis
  • Tuberculosis (TB) remains a significant global health issue, with a study in China investigating the occurrence of concurrent pulmonary tuberculosis (PTB) and extrapulmonary tuberculosis (EPTB).
  • The research analyzed data from nearly 439,000 TB patients over several years and identified PTB as the most common diagnosis, with over 29% of cases showing concurrent PTB and EPTB, particularly tuberculous pleurisy.
  • Results indicated variations in associations of concurrent PTB-EPTB by gender and age, highlighting the importance for clinicians to screen for these cases to enhance patient treatment outcomes.

Kidney stone disease (KSD) is one of the earliest medical diseases known, but the mechanism of its formation and metabolic changes remain unclear. The formation of kidney stones is a extensive and complicated process, which is regulated by metabolic changes in various substances. In this manuscript, we summarized the progress of research on metabolic changes in kidney stone disease and discuss the valuable role of some new potential targets.

Background: Testicular germ cell tumor (TGCT) is the most common tumor in young men, but molecular signatures, especially the alternative splicing (AS) between its subtypes have not yet been explored.

Methods: To investigate the differences between TGCT subtypes, we comprehensively analyzed the data of gene expression, alternative splicing (AS), and somatic mutation in TGCT patients from the TCGA database. The gene ontology (GO) enrichment analyses were used to explore the function of differentially expressed genes and spliced genes respectively, and Spearman correlation analysis was performed to explore the correlation between differential genes and AS events.

Article Synopsis
  • Researchers have developed nitrogen-rich porous carbon materials from biomass waste (soybean dregs) that effectively capture carbon dioxide (CO) for potential chemical conversion.
  • These materials show impressive CO adsorption capabilities, with a capacity of 6.3 mmol/g at 0°C, due to their unique porous structure and nitrogen content.
  • Using the synthesized carbon as a catalyst support, the process allows for the efficient transformation of captured CO into valuable chemicals without significant energy costs, showcasing an innovative way to utilize waste and CO simultaneously.

The COVID-19 pandemic caused by SARS-CoV-2 infections has led to excess deaths worldwide. Neutralizing antibodies (nAbs) against viral spike protein acquired from natural infections or vaccinations contribute to protection against new- and re-infections. Besides neutralization, antibody-mediated cellular cytotoxicity (ADCC) and phagocytosis (ADCP) are also important for viral clearance.

Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is characterized by a strong production of inflammatory cytokines such as TNF and IL-6, which underlie the severity of the disease. However, the molecular mechanisms responsible for such a strong immune response remains unclear. Here, utilizing targeted tandem mass spectrometry to analyze serum metabolome and lipidome in COVID-19 patients at different temporal stages, we identified that 611 metabolites (of 1,039) were significantly altered in COVID-19 patients.

Photocatalytic synthesis has emerged as an efficient route to transform CO into functionalized organic carbamates by photocatalysis. Herein, a catalyst-free carbamoyloxylation of arylacetones with CO and amines under visible light was developed for the synthesis of -β-oxoalkyl carbamates in yields up to 93%. This protocol proceeded smoothly with the assistance of inexpensive carbon tetrabromide at room temperature under atmospheric CO pressure, leading to simultaneous construction of C-O and C-N bonds.
