Radiation resistance in head and neck squamous cell carcinoma (HNSCC), driven by intrinsic and extrinsic factors, poses a significant challenge in radiation oncology. The key contributors are tumor hypoxia, cancer stem cells, cell cycle checkpoint activation, and DNA repair processes (homologous recombination and non-homologous end-joining). Genetic modifications such as TP53 mutations, KRAS mutations, EGFR overexpression, and abnormalities in DNA repair proteins like BRCA1/2 additionally affect radiation sensitivity.

Background: The functional diversity of microtubules is regulated through the expression of distinct α- and β-tubulin isotypes together with several post-translational modifications, a concept known as tubulin code. Tubulin detyrosination is a reversible post-translational modification which consists in the removal of the genetically encoded C-terminal tyrosine residue of most α-tubulins. While this modification has been observed in the megakaryocyte lineage, its importance remains poorly understood in platelet biogenesis.

Artificial intelligence (AI) holds great promise for analyzing complex data to advance patient care and disease research. For example, AI interpretation of retinal imaging may enable the development of noninvasive retinal biomarkers of systemic disease. One potential limitation, however, is government regulation regarding retinal imaging as biometric data, which has been recently under debate in the United States.

Nanotechnology has shown great potential to improve agricultural production and increase crop tolerance to abiotic stresses, including saline-alkaline environments. This study focuses on the biological mechanism of biocompatible iron-doped carbon dots (Fe-C-dots) nanozyme biosynthesized from artemisinin extract to alleviate saline-alkaline stress in wheat (Triticum aestivum L.).

Inherited bone marrow failure syndromes (IBMFS) are genetic disorders of impaired hematopoiesis that manifest in childhood with both cytopenias and extra-hematologic findings. While several IBMFS are categorized as ribosomopathies due to shared underlying ribosomal dysfunction, there is a broader disruption of the protein homeostasis (proteostasis) network across both classic and emerging IBMFS. Precise regulation of the proteostasis network, including mechanisms of protein synthesis, folding, trafficking, and degradation as well as associated stress response pathways, has emerged as essential for maintaining hematopoietic stem cell (HSC) function, providing new potential mechanistic insights into IBMFS pathogenesis.
