Summary: This study analyzes the molecular landscape of cancer-associated stroma (CAS) in cutaneous squamous cell carcinoma (cSCC) and identifies changes in immune cells and the influence of perineural infiltration (PNI) on CAS. The results demonstrate immune exhaustion markers in CAS of cSCC and an increase in IL-17A with PNI. These findings support further research on immunotherapy and anti-IL-17A in cSCC, particularly for cases with PNI.

Summary: By performing RNAseq transcriptomic profiling of 110 patient samples, we revealed a disease continuum from normal sun-exposed skin to precancerous actinic keratosis (AK), and then to malignant invasive cutaneous squamous cell carcinoma (cSCC) and potentially lethal metastatic disease. This progression is accompanied by the suppression of master regulators of epidermal differentiation, dynamic modulation of the epidermal differentiation complex, remodelling of the immune landscape, and an increase in tumor specific keratinocytes. Our study provides a comprehensive map of the cSCC disease continuum and reveals potentially actionable events that promote and accompany disease progression.

Summary: Animal studies in the 1920s showed that vitamin A deficiency could lead to cancer in epithelial tissues, but typically results in death in humans. Recent research indicates that a high dietary intake of vitamin A can reduce the risk of skin cancer, specifically caused by excess exposure to UVB. This highlights the potential importance of vitamin A in preventing certain types of cancer.

Summary: Cutaneous squamous cell carcinoma (cSCC) cells secrete a higher number of extracellular vesicles (EVs) compared to normal human epidermal keratinocytes (NHEKs). Inhibiting the secretion of EVs from cSCC cells can suppress tumor growth in a xenograft model. EVs derived from metastatic cSCC cells induce the conversion of fibroblasts into cancer-associated fibroblasts (CAFs).

Summary: ANLN promotes cytokinesis and proliferation in ESCC cells and is associated with poor prognosis in ESCC patients. USP10 interacts with ANLN and regulates its protein levels by removing ubiquitin chains, preventing ANLN degradation. USP10 stabilizes ANLN and promotes contractile ring assembly and cytokinesis. F806 targets USP10 and promotes ANLN degradation, inhibiting ESCC cell mitosis.

Summary: Chronic pain is a major health problem that affects disability and quality of life. Current treatments for chronic pain are ineffective, so there is a need for new analgesics. In this study, the researchers tested the efficacy of selective androgen receptor modulators (SARMs) in a mouse model of muscle pain. They found that SARMs alleviated muscle hyperalgesia in both male and female mice, and this effect was mediated through androgen receptors. The SARM-loaded microparticles released the drug for a sustained period and did not produce toxic or rewarding effects. These findings suggest that SARM-loaded microparticles could be a potential therapy for chronic muscle pain.

Summary: Mice with a specific amino acid substitution in SHP1 protein (Ptpn6(spin) mice) develop an autoinflammatory disease. When Ptpn6(spin) bone marrow cells are transferred into Cd47-deficient mice, marked weight loss and death occur. The study suggests that gut leakage caused by pathogenic neutrophils may contribute to the morbidity and mortality in Cd47(-/-) mice receiving Ptpn6(spin) cells. IL-1 blockade with anakinra can rescue the disease phenotype.

Summary: Our objective was to qualify MUC5AC and MUC5B immunohistochemical techniques to provide a useful tool for studying mucin tissue in CF and other ferret models. Results showed that MUC5AC and MUC5B mucins were most commonly detected in large airways and least in small airways, consistent with goblet cell density in airway surface epithelia. We also found that stomach tissues were enriched in MUC5AC and gallbladder tissues were enriched in MUC5B, similar to human tissues. Qualified techniques for MUC5AC and MUC5B immunohistochemistry will be valuable for mucin tissue studies.

Summary: This study investigated the immunomodulatory effects of inhalation exposure to copper oxide nanoparticles (CuO NPs) in different immune conditions. The results showed that CuO NP exposure decreased T(H)1 and T(H)2 cells and increased T-bet(+) Treg cells in healthy mice. However, CuO NP inhalation exposure resulted in decreased T(H)2 responses and increased T-bet(+) Treg cells in mice with house dust mite (HDM) asthma, and increased T(H)2 cells in AIT-treated asthmatic mice.
