We describe an immunohistochemical technique that makes use of two monoclonal antibodies (MAb), one to detect the transforming growth factor B (TGFB) and another that reacts with iodo- and bromodeoxyuridine. The purpose of this technique is to determine the relationship between TGFB expression and the S-phase cells in human tumors. Since both can be distinctly identified in situ from tissue embedded in plastic, in assessment of the geographic orientation of S-phase cells in relation to such factors as TGFB, contiguity to blood vessels, nerve fibers, and macrophages can also be achieved.

Background: Curcumin (Cur) is a polyphenol phyto-compound found in turmeric () that inhibits tumorigenesis by introducing apoptosis and restricting cell survival and proliferation. This in vitro research article focuses on the pharmacodynamic interactions of Cur combined with the commercial drug doxorubicin (Doxo) to enhance the cytotoxicity of Doxo at lower doses against triple-negative breast cancer cells (MDA-MB-231) with the chemo-protective effect against normal HEK293 cells. In this study, we observed the dose-dependent cytotoxicity, increased reactive oxygen species (ROS) generation, and increased chromatin condensation in combination doses compared to single doses.

Double C-2 Like Domain Beta (DOC2B) located at 17q13.3 prevents metastasis by senescence induction and epithelial to mesenchymal transition inhibition in cervical cancer (CC). The extracellular vesicle (EV) mediated trafficking of DOC2B and its impact on tumor suppressive activity are not investigated in CC.

Current temporal studies of DNA replication are either low-resolution or require complex cell synchronisation and/or sorting procedures. Here we introduce Nanotiming, a single-molecule, nanopore sequencing-based method producing high-resolution, telomere-to-telomere replication timing (RT) profiles of eukaryotic genomes by interrogating changes in intracellular dTTP concentration during S phase through competition with its analogue bromodeoxyuridine triphosphate (BrdUTP) for incorporation into replicating DNA. This solely demands the labelling of asynchronously growing cells with an innocuous dose of BrdU during one doubling time followed by BrdU quantification along nanopore reads.

Various factors and mechanisms, including radiation, initiate cellular senescence and are concurrent with the progression of various neurodegenerative diseases. Radiation-induced chromosomal aberrations and DNA integrity damage impact the processes of cellular growth, maturation, and aging. Astragaloside IV (AS-IV) has been documented to display significant neuroprotective effects on inflammation, oxidative stress, and cellular apoptosis; however, the precise neuroprotective mechanism of AS-IV against neuronal aging remains unclear.
