High throughput screening led to the discovery of a novel series of quinazolin-2-ylamino-quinazolin-4-ols as a new class of DNA polymerase III inhibitors. The inhibition of chromosomal DNA replication results in bacterial cell death. The synthesis, structure-activity relationships and functional activity are described.

The rising global incidence of syphilis underscores the risk of transmission through blood transfusions. Treponema pallidum, the pathogen responsible for syphilis, represents a major public health challenge. Accurate detection is essential for controlling the disease, particularly in asymptomatic blood donors.

Background: The insulin-like growth factor 2 (IGF2) and H19 are overexpressed in hepatocellular carcinoma (HCC). IGF2-derived miR-483-5p is implicated in the development of cancers. Here, we investigated the involvement of miR-483-5p in IGF2 and H19 overexpression regulation and its role in HCC.

Pseudouridine (Ψ) is an abundant RNA chemical modification that plays critical biological functions. Current Ψ detection methods are limited in identifying Ψs at base-resolution in U-rich sequence contexts, where Ψ occurs frequently. Here we report "Mut-Ψ-seq" that utilizes the classic N-cyclohexyl N'-(2-morpholinoethyl)carbodiimide (CMC) agent and an evolved reverse transcriptase ("RT-1306") for Ψ mapping at base-resolution.

Coupling interactions between the alpha (α) subunit of the polymerase III core (α-Pol III core) and the tau (τ) subunit of the clamp loader complex (τ-CLC) are vital for efficient and rapid DNA replication in Escherichia coli (E. coli). Specific and targeted mutations in the C-terminal τ-interaction region of the Pol III α-subunit disrupted efficient coupled rolling circle DNA synthesis in vitro and caused significant genomic defects in CRISPR-Cas9 dnaE edited cell strains.

Captive, pelagic red crabs (Pleuroncodes planipes) had shortened lifespans and cutaneous black spots. Histologically, epidermal and mesenchymal cells had 3-5 µm diameter intranuclear inclusions, necrosis, vacuolation, and/or hyperplasia. The remaining organs were histologically unremarkable.
