Mammary serine protease inhibitor (maspin) is a tumor suppressor protein downregulated during carcinogenesis and cancer progression; cytoplasmic-only maspin expression is an independent, unfavorable prognostic indicator in patients with lung squamous cell carcinoma (LUSC). We hypothesized that the cytoplasmic-only localization of maspin has tumor-promoting functions in LUSC. The subcellular localization of maspin and the invasive capability of LUSC cell lines were investigated using RNA sequencing (RNA-seq), Western blotting, and siRNA transfection.

Space-division multiplexing enables tuning a set of weight coefficients as an optical parameter and obtaining the desired Ising Hamiltonian at a time. We solved knapsack problems to verify the system's validity, demonstrating that optical parameters impact the search property.

- HIF-PHIs are a new class of medications for treating renal anemia in chronic kidney disease (CKD) patients, affecting various biological processes beyond just red blood cell production.
- A study analyzed plasma metabolomic profiles in 10 hemodialysis patients who switched from erythropoiesis-stimulating agents to the HIF-PHI daprodustat, revealing significant changes in four metabolites and notable changes in five others.
- The findings suggest alterations in key metabolic pathways after switching medications, highlighting the need to further explore the potential side effects of long-term HIF-PHI use in CKD patients.
The knowledge of microplastic (MP) age could aid the deduction of the origin and fate of a fragment carried by ocean currents over long time periods and distances. The present study developed a novel method to estimate the age of MPs (i.e.

This study evaluated the prognostic impact of MYC family protein expression in patients with surgically resected HGNEC.
Methods: Immunohistochemical analyses were performed on 83 resected specimens of HGNEC using antibodies against MYC family proteins (c-MYC, n-MYC, and l-MYC).
