Enhancing cancer therapy: The role of drug delivery systems in STAT3 inhibitor efficacy and safety.

The signal transducer and activator of transcription 3 (STAT3), a member of the STAT family, resides in the nucleus to regulate genes essential for vital cellular functions, including survival, proliferation, self-renewal, angiogenesis, and immune response. However, continuous STAT3 activation in tumor cells promotes their initiation, progression, and metastasis, rendering STAT3 pathway inhibitors a promising avenue for cancer therapy. Nonetheless, these inhibitors frequently encounter challenges such as cytotoxicity and suboptimal biocompatibility in clinical trials.

Split-Lobe for Tumor between Left S3 and S4 by Uniportal Video-Assisted Thoracoscopy.

Video-assisted thoracoscopic surgery (VATS) segmentectomy is an optimal treatment for malignant pulmonary ground glass nodules (GGNs). However, this surgery is complicated when tumors are located between more than two adjacent segments, although combined subsegmentectomy ensures sufficient margin under uniportal approach. Lobectomy might be inevitable, especially when resecting deep nodules in the central left upper lung lobe.

Structural and Energetic Origin of Different Product Specificities and Activities for SETD3 and Its Mutants on the Methylation of the β-Actin H73K Peptide: Insights from a QM/MM Study.

The methylation of the lysine residue can affect some fundamental biological processes, and specific biological effects of the methylations are often related to product specificity of methyltransferases. The question remains concerning how active-site structural features and dynamics control the activity as well as the number (1, 2, or 3) of methyl groups on methyl lysine products. SET domain containing protein 3 (SETD3) has been identified recently as the β-actin histidine73-N methyltransferase, and also, it has a weak methylation activity on the H73K β-actin peptide for which the target H73 residue is mutated into K73.

3H-leucine single-injection method for determining endogenous amino acid losses of broilers.

Objective: A 3H-leucine (3H-Leu) single-injection method was proposed for determining the endogenous amino acid losses of broilers. This method was based on the hypothesis that the ratio of the specific radioactivity (SR) of endogenous Leu in excreta (SRe) to that of free Leu in trichloroacetic acid-soluble plasma (SRp) remains constant after a single subcutaneous injection of 3H-Leu into birds fed different diets.

Methods: Two experiments were designed to clarify this hypothesis.
