Hepatitis C virus (HCV) infection is a leading cause of liver disease worldwide. The HCV RNA genome is translated into a single polyprotein. Most of the cleavage sites in the non-structural (NS) polyprotein region are processed by the NS3/NS4A serine ...

Co-transcriptional RNA cleavage provides a failsafe termination mechanism for yeast RNA polymerase I
Ribosomal RNA, transcribed by RNA polymerase (Pol) I, accounts for most cellular RNA. Since Pol I transcribes rDNA repeats with high processivity and polymerase density, transcription termination is a critical process.

Clinical analysis reveals significant dysregulation of FGFRL1 in esophageal cancer (EC) patients. RNAi‐coupled next‐generation sequencing (NGS) and in vitro study reveal FGFRL1‐mediated EC progression via EMT, PI3K/Akt, and Notch pathways. Functional assays confirm its role in tumor growth, migration, and invasion.

KLK7, a tissue kallikrein‐related peptidase, is elevated in advanced colorectal cancer and associated with shorter survival. High KLK7 levels in ascites correlate with peritoneal metastasis. In mice, KLK7 overexpression increases metastasis. In vitro, KLK7 enhances cancer cell proliferation, migration, adhesion, and spheroid formation, driving ...

dUTPases are involved in balancing the appropriate nucleotide pools. We showed that dUTPase is essential for normal development in zebrafish. The different zebrafish genomes contain several single‐nucleotide variations (SNPs) of the dut gene. One of the dUTPase variants displayed drastically lower protein stability and catalytic efficiency as compared ...

RNase P-Mediated Sequence-Specific Cleavage of RNA by Engineered External Guide Sequences
The RNA cleavage activity of RNase P can be employed to decrease the levels of specific RNAs and to study their function or even to eradicate pathogens. Two different technologies have been developed to use RNase P as a tool for RNA knockdown.

Kinetics and mechanism in RNA cleavage. [PDF]
Experimental studies on the cleavage of various RNA molecules--poly(U), 3',5''-UpU, 2',5''-UpU, and 3',5''-ApA--catalyzed by imidazole buffers show that there is a sequential bifunctional mechanism. One catalyst species converts the substrate to an intermediate phosphorane, and the second catalyst converts the phosphorane to cleavage products. Detailed

Chemoresistance in bladder cancer: Macrophage recruitment associated with CXCL1, CXCL5 and CXCL8 expression is characteristic of Gemcitabine/Cisplatin (Gem/Cis) Non‐Responder tumors (right side) while Responder tumors did not show substantial tumor‐stromal crosstalk (left side). All biological icons are attributed to Bioicons: carcinoma, cancerous‐cell‐

Induction of membrane rearrangements in the cytoplasm of infected cells is a hallmark of positive-strand RNA viruses. These altered membranes serve as scaffolds for the assembly of viral replication factories (RFs).

HIV‐1 establishes immediate latency in T cells expressing the viral Nef protein
Nef is a viral protein often omitted from HIV‐1 reporter viruses. Consequently, its role in viral latency is unclear. We developed three novel dual reporter HIV‐1 derivatives that express Nef and allow for detection of latent and productive infection. Using these reporters, we show that Nef does not affect the establishment of immediate viral latency ...
