Summary: Dysregulation of DNA repair is a characteristic of cancer. This study identifies STAT3 as a novel transcriptional regulator of XRCC1 in triple-negative breast cancers. Glucose challenge increases STAT3 activation, promoting XRCC1 expression in different cell types. Prolonged exposure to high glucose leads to overexpression of XRCC1, which can be reversed by restricting glucose intake and down-regulating STAT3 activation.

Summary: Chromosome bridges in cancer cells are often formed and may break during mitosis, with a direct correlation between the distance between bridge kinetochores and bridge breakage. The mechanisms responsible for chromosome bridge breakage during mitosis may depend on the separation between the bridge kinetochores. Previous studies have suggested mechanical stress or biochemical digestion as possible causes of bridge breakage in interphase cells, suggesting a multifactorial model for bridge breakage.

Summary: By doping phosphorus into two-dimensional single-crystalline quaternary sulfide nanobelts, this study achieved significantly enhanced photocatalytic hydrogen production efficiency. The introduction of phosphorus led to a narrowed band gap, inhibited carrier recombination, and increased electric conductivity, contributing to the improved catalytic performance.

Summary: Cytogenetic approaches are important for evaluating the genetic effects of mutagenic treatments, and although they are time-consuming, they are essential for studying cytotoxic and genotoxic effects and environmental monitoring. The micronucleus test is an important method for studying genotoxicity in plants, and recent advancements have expanded the scope of cytogenetic techniques beyond the detection of chromosome aberrations. However, there is limited knowledge about micronuclei in plants compared to humans and animals.

Summary: DNA damage is a common event in every cell, and proteins of the DNA damage response network play a crucial role in sensing and repairing DNA lesions. Genetic defects in DNA repair proteins can lead to immunodeficiency, bone marrow failure syndromes, and increased cancer susceptibility. DDR biomarkers are useful for diagnosing NHEJ defects and AT, with some limitations depending on the specific DNA repair deficiency.

Summary: The study investigated the mobility of chromosomes and double-strand break (DSB) sites in response to DNA damage in Arabidopsis thaliana. The results showed an increase in chromatin mobility, particularly in the S/G2 phases of the cell cycle. This increased mobility was dependent on the DNA damage response transcription factor sog1-1 and the HR factor RAD54, suggesting a role of chromatin mobility in the early steps of the DNA damage response.

Summary: The study found that veterans with traumatic brain injury (TBI) are more likely to develop sleep disorders, including sleep apnea, insomnia, hypersomnia, and sleep-related movement disorders. This association is stronger in mild TBI patients and remains even after a 2-year time lag, regardless of the presence of posttraumatic stress disorder.

Summary: The DNA damage response (DDR) pathways are important for sensing DNA damage and coordinating repair mechanisms. This study investigated the dysregulation of the transcriptome in breast cell lines under different glucose levels. Bioinformatics analysis revealed that multiple DDR genes were significantly upregulated in both normal and cancerous breast cell lines grown in high glucose (HG). Wet lab experiments confirmed that HG induced severe DNA damage in triple-negative breast cancer (TNBC) cells, and qPCR analysis confirmed the upregulation of DDR genes. These results suggest that DDR pathways are crucial for counteracting DNA damage induced by high glucose.

Summary: Hypothyroidism is characterized by insufficient thyroid hormone activity, leading to reduced goblet cells in the intestine, which can be rescued by T3 treatment. Transcriptome profiling revealed differential gene expression in the intestine of hypothyroid adults, with Fgf19-Fgfr4 signaling pathway being associated with inhibition of goblet cell differentiation in hypothyroidism. Targeting the TH and Fgf19-Fgfr4 signaling pathways could be a potential treatment for TH-related gastro-intestinal diseases.

Summary: The loss of LAP2 alpha leads to the formation of larger, biochemically stable lamin A/C structures in the nuclear interior that are inaccessible to lamin A/C antibodies. Binding of LAP2 alpha to lamin A/C inhibits the formation of higher order structures, keeping nucleoplasmic lamin A/C in a mobile state. This suggests that LAP2 alpha is essential for maintaining a mobile lamin A/C pool in the nuclear interior, necessary for proper nuclear functions.

Summary: Morphological and genetic analyses identified four clusters of Chthamalus species in the Western Indian Ocean. A newly identified species, C. barilani, was found in Madagascar, Zanzibar, and Tanzania. Genetic distance analyses confirmed the presence of multiple cryptic species within C. malayensis and revealed additional genetic diversity among Chthamalus populations in the region.

Summary: The circadian clock is a mechanism that regulates various physiological rhythms with a period of approximately 24 hours. A mutation in FBXL3 has been found in patients with syndromic developmental delay, morphological abnormalities, and intellectual disability. Using zebrafish as a model, it was discovered that loss of fbxl3a function disrupts the circadian rhythms, locomotor activity, and sleep-wake cycles, but does not cause morphological effects. These findings suggest a conserved role for FBXL3 in the circadian clock system across vertebrates and its acquisition of developmental roles in humans.
