We recently developed a novel transcriptome analysis method, termed 5'-bromo-uridine (BrU) immunoprecipitation chase-deep sequencing analysis (BRIC-seq). BRIC-seq enables the determination of genome-wide RNA stability by chasing chronological decreases of BrU-labeled RNAs under physiologically undisturbed conditions. The RNA half-life of each transcript is calculated from the decreasing number of BrU-labeled RNA sequence tags measured by deep sequencing of BrU-labeled RNAs. Here, we describe a detailed protocol and provide tips for BRIC-seq, followed by computational analysis.

Objectives: Bladder cancer is a common malignancy with high incidence and poor prognosis. N-methyladenosine (mA) modification is widely involved in diverse physiological processes, among which the mA recognition protein YTH N-methyladenosine RNA binding protein F2 (YTHDF2) plays a crucial role in bladder cancer progression. This study aims to elucidate the molecular mechanism by which O-linked -acetylglucosamine (O-GlcNAc) modification of YTHDF2 regulates its downstream target, period circadian regulator 1 (), thereby promoting bladder cancer cell proliferation.

The Mediterranean Basin, a hotspot for tomato production, is one of the most vulnerable areas to climate change, where rising temperatures and increasing soil and water salinization represent major threats to agricultural sustainability. Thus, to understand the molecular mechanisms behind plant responses to this stress combination, an RNA-Seq analysis was conducted on roots and shoots of tomato plants exposed to salt (100 mM NaCl) and/or heat (42°C, 4 h each day) stress for 21 days. The analysis identified over 8000 differentially expressed genes (DEGs) under combined stress conditions, with 1716 DEGs in roots and 2665 in shoots being exclusively modulated in response to this specific stress condition.

The UPF0235 UniProt family proteins are conserved across archaea, bacteria, and eukaryotes; however, they remain functionally uncharacterized. Here, we report the high resolution (1.3 Å) crystal structure of UPF0235 protein (PF1765, UniProt: Q8U052) from Pyrococcus furiosus.

The Colorado potato beetle (CPB, Leptinotarsa decemlineata) is a major pest of solanaceous crops and has developed resistance to many conventional insecticides, highlighting the need for novel, environmentally sustainable control strategies. In this study, we evaluated the efficacy of RNA interference (RNAi) targeting the proteasome subunit β5 (PSMB5) gene as a biopesticide approach against CPB larvae. Double-stranded RNA (dsRNA) targeting PSMB5 (a highly specific dsRNA) and Actin (a less specific dsRNA) dsRNA was synthesized and applied via leaf dip assays, either in naked form or formulated with chitosan nanoparticles.

Colorectal cancer (CRC) remains one of the most lethal malignancies globally, driven by complex molecular mechanisms that contribute to its progression and metastasis. This study focuses on the role of N1-methyladenosine (mA) RNA methylation in CRC, particularly its effect on Rab Interacting Lysosomal Protein-Like 1 (RILPL1) expression and the downstream activation of the CaMKII/CREB signaling pathway. Bioinformatics analysis identified RILPL1 as a key gene associated with poor CRC prognosis, exhibiting increased expression levels in cancerous tissues, with further elevation in metastatic samples.
