Aggressive prostate cancer is associated with pericyte dysfunction

Molecular Oncology, EarlyView.
Tumor‐produced TGF‐β drives pericyte dysfunction in prostate cancer. This dysfunction is characterized by downregulation of some canonical pericyte markers (i.e., DES, CSPG4, and ACTA2) while maintaining the expression of others (i.e., PDGFRB, NOTCH3, and RGS5).

Detection of Diffuse Hot Gas around the Young, Potential Superstar Cluster H72.97–69.39

The Astrophysical Journal
We present the first Chandra X-ray observations of H72.97–69.39, a highly embedded, potential superstar cluster in its infancy located in the star-forming complex N79 of the Large Magellanic Cloud. We detect particularly hard, diffuse X-ray emission that

Properties of H II region populations in galaxies. I - The first-ranked H II regions

The Astrophysical Journal, 1988
H-alpha photometry of the brightest H II regions in 95 nearby spiral and irregular galaxies has been analyzed in order to study the dependence of the H II region populations on the properties of their parent galaxies. It is found that the brightest H II regions in Magellanic irregular galaxies are about 50 times brighter than those in early-type ...

The neural crest‐associated gene ERRFI1 is involved in melanoma progression and resistance toward targeted therapy

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.

ALMA-QUARKS: Few-thousand-year “Hatching out of the Egg:” The Supersonic Breakout of a Hypercompact H II Region from Its Parental Hot Core

The Astrophysical Journal
The kinematic evolution of hypercompact (HC) H ii regions around young high-mass stars remains poorly understood due to complex interactions with parental environs.

Plasma extrachromosomal circular DNA as a biomarker in EGFR‐targeted therapy of non‐small cell lung cancer

Molecular Oncology, EarlyView.
Detection of extrachromosomal circular DNA (eccDNA) in plasma samples from EGFR‐mutated non‐small cell lung cancer patients. Plasma was collected before and during treatment with the EGFR‐tyrosine kinase inhibitor osimertinib. Plasma eccDNA was detected in all cancer samples, and the presence of the EGFR gene on eccDNA serves as a potential biomarker ...

Investigating H II Regions in the Disk of NGC 7331 with the Circumgalactic Hα Spectrograph

The Astrophysical Journal
We investigate the ionized gas kinematics of H ii regions in the disk of NGC 7331 using integral field unit data collected with the Circumgalactic H α Spectrograph (CH α S).
