Molecular Oncology, EarlyView.Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells
Molecular Oncology, EarlyView.This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.

Synchronized SVM‑Based Speed Regulation for Induction Motors
Nanjing Hangkong Hangtian Daxue XuebaoIn high-power drives， the switching frequency is even less than 1 kHz for low losses， but phase currents will contain huge harmonics. To solve it， this paper proposes the stator flux trajectory tracking （SFTT） based realization of synchronized space ...

Research on performances of speed regulating mechanism of mine-used permanent magnet speed regulator
Gong-kuang zidonghua, 2018 Structure and principles of mine-used permanent magnet speed regulator were introduced. A sinusoidal-based speed regulating groove was designed and contact stress of the groove was analyzed by finite element method. Axial force and air gap value in the permanent magnetic speed regulator were fitted by function curve, according to characteristic ...

Molecular Oncology, EarlyView.Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated
