Background: Thymidine kinases (TKs) are key enzymes involved in DNA synthesis and repair, with alterations in their expression associated with various cancers. Thymidine kinase 1 (TK1) and TK2 are cytosolic enzyme proteins that catalyze the addition of a gamma-phosphate group to thymidine. The existing literature on TK1 in cervical squamous cell carcinoma (CESC) fails to address the clinical role of TK1 overexpression and its possible molecular mechanism in CESC.

Biallelic pathogenic variants in cause a fatal autosomal recessive multisystem disorder characterized by recurrent autoinflammation, hypomyelination, progressive neurodegeneration, microcephaly, failure to thrive, liver dysfunction, respiratory chain defects and accumulation of glycogen in skeletal muscle. No missense variants in have been reported to date.We report a 6-year-old boy with microcephaly, global developmental delays, lower limb spasticity with hyperreflexia, epilepsy, abnormal brain MRI, failure to thrive, recurrent fevers and transaminitis.

The biosynthesis of mupirocin, a clinically significant antibiotic produced by sp. NCIMB 10586, is activated by the -acyl homoserine lactone (AHL) MupR/I quorum sensing (QS) system. However, to date, limited research has focused on the influence of global regulators such as the GacS/A two-component system (TCS) on the MupR/I QS system or mupirocin biosynthesis.

Type 2 diabetes mellitus (T2DM) and obesity are critical global health issues with rising incidence rates. Glucagon-like peptide-1 (GLP-1) analogues have emerged as effective treatments due to their ability to regulate blood glucose levels and gastric emptying through central nervous signals involving hypothalamic receptors, such as leptin. To address the short plasma half-life of native GLP-1, a C-16 fatty acid was conjugated to lysine in the GLP-1 analogue sequence to enhance its longevity.

Heat stress significantly impacts global rice production, highlighting the critical need to understand the genetic basis of heat resistance in rice. U2AF (U2 snRNP auxiliary factor) is an essential splicing complex with critical roles in recognizing the 3'-splice site of precursor messenger RNAs (pre-mRNAs). The U2AF small subunit (U2AF35) can bind to the 3'-AG intron border and promote U2 snRNP binding to the branch-point sequences of introns through interaction with the U2AF large subunit (U2AF65).
