MicroRNAs (miRNAs) are important post-transcriptional regulators of gene expression and play vital roles in various biological processes. It has been reported that aberrant regulation of miRNAs was associated with the development and progression of various diseases, but the underlying mechanisms are not fully deciphered. Here, we described our updated TransmiR v2.0 database for more comprehensive information about transcription factor (TF)-miRNA regulations. 3730 TF-miRNA regulations among 19 species from 1349 reports were manually curated by surveying >8000 publications, and more than 1.7 million tissue-specific TF-miRNA regulations were further incorporated based on ChIP-seq data. Besides, we constructed a 'Predict' module to query the predicted TF-miRNA regulations in human based on binding motifs of TFs. To facilitate the community, we provided a 'Network' module to visualize TF-miRNA regulations for each TF and miRNA, or for a specific disease. An 'Enrichment analysis' module was also included to predict TFs that are likely to regulate a miRNA list of interest. In conclusion, with improved data coverage and webserver functionalities, TransmiR v2.0 would be a useful resource for investigating the regulation of miRNAs. TransmiR v2.0 is freely accessible at http://www.cuilab.cn/transmir.

Department of Oncology, The First Affiliated Hospital of Anhui Medical University, 218 Jixi Road, Shushan District, Hefei, Anhui Province, 230022, China.
Objective: To explore the potential of endoplasmic reticulum stress (ERS)-associated protein CLIP4 as a biomarker for hepatocellular carcinoma (HCC) and the underlying mechanism.
Methods: TCGA public database and a tissue microarray were used to investigate the molecular characteristics of CLIP4 and its association with disease. TCGA-LIHC dataset was used for single-gene differential expression analysis, single-gene correlation analysis, functional enrichment analysis, immune infiltration analysis, and DNA methylation analysis.
Bioinformatics analysis reveals potential crosstalk genes and molecular mechanisms between ulcerative colitis and psoriasis.

Ulcerative colitis (UC) and psoriasis are highly correlated clinically; however, it is unclear whether they have a common pathophysiological mechanism. The purpose of this study is to investigate the important molecules and pathways that mediate the coexistence of UC and psoriasis through quantitative bioinformatics analysis of public RNA-sequencing databases. The UC (GSE38713) and psoriasis (GSE30999) datasets were downloaded from the Gene Expression Omnibus database.

Article Synopsis
- The COVID-19 pandemic has resulted in increased cases of co-infection with SARS-CoV-2 and the Kaposi's sarcoma-associated herpesvirus (KSHV), leading to higher mortality rates due to the lack of targeted treatments.
- Cambogin, a natural product, has shown promise in reducing tumors associated with KSHV in mice, but its effects on SARS-CoV-2 were not fully understood until recent research.
- The study reveals that Cambogin targets 46 host genes affected by both viruses and effectively inhibits SARS-CoV-2 replication while also slowing the growth of KSHV-induced tumors, suggesting its potential as a treatment for patients co-infected with both viruses.

MicroRNAs (miRNAs) are small non-coding RNAs that regulate gene expression by binding to the 3'-untranslated regions of target mRNAs, influencing various biological processes at the post-transcriptional level. Identifying miRNA transcription start sites (TSSs) and transcription factors' (TFs) regulatory roles is crucial for elucidating miRNA function and transcriptional regulation. miRStart 2.
