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.

Analytical Models for HF-Losses of Litz Wire in Inductors With Arbitrary Winding and Gap Arrangements

IEEE Open Journal of Power Electronics
Dueto 2D fields in the core window of inductors (e.g. the fringing field caused by core gaps) large errors can occur in the winding loss calculation, when the assumptions, that the $H$-field is parallel to the winding layers and constant along the field ...

Suppression of EMI radiation noise by inductor current recoil on boost PFC

The Journal of Engineering, 2018
As the development of switching power and power factor correction (PFC) technology in electronic devices, there is strong transient current rate and electromagnetic interference (EMI) noise caused by switching power supply MOSFET, IGBT, and other ...

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

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

Development of inductive-loaded ultra-wideband monopole antennas from stepped-impedance resonators

The Journal of Engineering, 2019
An ultra-wideband (UWB) printed monopole antenna is designed from stepped-impedance resonator (SIR) geometry. An inductor which is loaded in series between the radiating strips combines the multiple resonance bands of a two-strip stepped-impedance ...

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

Molecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

Molecular Oncology, EarlyView.
Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

Switched-inductor VCO based on tapped vertical solenoid inductors

Electronics Letters, 2012
A new switched-inductor voltage controlled oscillator (VCO) scheme based on tapped vertical solenoid inductors is presented. With tapping ports, various effective inductances are selected by switches for multi-band operation. As a proof of concept, two VCOs, with one and two tapping ports separately, are implemented in a 0.18 m 1P6M standard CMOS ...
