Molecular Oncology, EarlyView.ERRFI1, a neural crest (NC)‐associated gene, was upregulated in melanoma and negatively correlated with the expression of melanocytic differentiation markers and the susceptibility of melanoma cells toward BRAF inhibitors (BRAFi). Knocking down ERRFI1 significantly increased the sensitivity of melanoma cells to BRAFi.

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

The Ultraviolet Spectra of Active Galaxies With Double-Peaked Emission Lines [PDF]
, 2004 We present the results of UV spectroscopy of AGNs with double-peaked Balmer emission lines. In 2/3 of the objects, the far-UV resonance lines are strong, with single-peaked profiles resembling those of Seyfert galaxies. The Mg II line is the only UV line

Emerging strategies to target metastasis and therapy resistance in melanoma
Molecular Oncology, EarlyView.Emerging studies propose new approaches to interfere with melanoma progression. In recognition of melanoma awareness month, at Molecular Oncology, we highlight recently published research articles, focusing on novel therapeutic targets driving metastatic spread and outlining different strategies to overcome resistance to BRAF inhibitors and anti‐PD‐1 ...
