Molecular Functions and Drug Prediction of MMP1 and TGFBR2 in Nasopharyngeal Carcinoma

Journal of Clinical Laboratory Analysis, EarlyView.
MMP1 and TGFBR2 were validated by machine learning and external datasets as the candidate genes. Dexamethasone showed strong binding affinity to MMP1 (−7.72 kcal/mol) and TGFBR2 (−7.27 kcal/mol) in docking studies. Knockdown of MMP1 repressed the malignant phenotypes of NPC cells.

Harmonic Analysis of Single-Phase Neutral-Point-Clamped Cascaded Inverter in Advanced Traction Power Supply System Based on the Big Triangular Carrier Equivalence Method

Energies, 2018
An advanced traction power supply system based on a single phase neutral-point-clamped (NPC) cascaded inverter is studied. The big triangular carrier equivalence method in double coordinate system is proposed, which can reduce one coordinate system, thus

Enhancement of immune checkpoint inhibitor efficacy by DHX58+ SELL+ T cells in advanced gastric cancer

VIEW, EarlyView.
We created a coculture system using patient‐derived organoids (PDOs) and tumor‐infiltrating lymphocytes (TILs) that mimics important interactions between PDOs and TILs in the presence of various ICIs. Our findings reveal that CD62L+ T cells, activated by CD44+ cancer stem cells (CSCs), facilitate tumor regression in samples sensitive to ICIs, which is ...

The Prognostic Significance of Tertiary Lymphoid Structures in Head and Neck Cancers: A Systematic Review and Meta‐Analysis

Journal of Oral Pathology &Medicine, EarlyView.
ABSTRACT Background Head and neck squamous cell carcinoma (HNSCC), particularly oral squamous cell carcinoma (OSCC), is associated with poor survival despite therapeutic advances. Tertiary lymphoid structures (TLSs) are emerging components of the tumor microenvironment, but their prognostic significance in HNSCC remains unclear.
