Census of Blue Straggler Stars in Distant Open Clusters and Maximum Fractional Mass Excess of Open Cluster Blue Straggler Stars

The Astronomical Journal
We identified blue straggler stars (BSSs) in 53 open clusters utilizing data from Gaia DR3. Most of these clusters are situated in the outer regions of the Galactic disk, encompassing structures such as the warp and the Outer arm.

ATF4‐mediated stress response as a therapeutic vulnerability in chordoma

Molecular Oncology, EarlyView.
We screened 5 chordoma cell lines against 100+ inhibitors of epigenetic and metabolic pathways and kinases and identified halofuginone, a tRNA synthetase inhibitor. Mechanistically halofuginone induces an integrated stress response, with eIF2alpha phosphorylation, activation of ATF4 and its target genes CHOP, ASNS, INHBE leading to cell death ...

A Census of Pulsars in Possible Association with Galactic Open Clusters

The Astrophysical Journal Letters
Among the ∼4000 known pulsars in our Galaxy, ≲10% are found in globular clusters, but none has been confirmed in any open clusters yet, although they outnumber globular clusters by about 20 times.

Cell surface interactome analysis identifies TSPAN4 as a negative regulator of PD‐L1 in melanoma

Molecular Oncology, EarlyView.
Using cell surface proximity biotinylation, we identified tetraspanin TSPAN4 within the PD‐L1 interactome of melanoma cells. TSPAN4 negatively regulates PD‐L1 expression and lateral mobility by limiting its interaction with CMTM6 and promoting PD‐L1 degradation.

Calibrating the Color–Magnitude Relation of M Giants by Using Open Clusters

The Astrophysical Journal Supplement Series
M giants, with their distinctive properties such as high luminosity, serve as excellent indicators for mapping the structure of the Milky Way. The distance to distant M giants can be determined by using the color–magnitude relation (CMR), which is ...

LDAcoop: Integrating non‐linear population dynamics into the analysis of clonogenic growth in vitro

Molecular Oncology, EarlyView.
Limiting dilution assays (LDAs) quantify clonogenic growth by seeding serial dilutions of cells and scoring wells for colony formation. The fraction of negative wells is plotted against cells seeded and analyzed using the non‐linear modeling of LDAcoop.

Comprehensive Analysis of NGC 6134: Structure, Dynamics, and Blue Straggler Star Candidates

The Astrophysical Journal Supplement Series
Open clusters play a critical role in the study of both stellar and Galactic evolution. We present a comprehensive analysis of the open cluster NGC 6134 using Gaia DR3 astrometric and photometric data, supplemented with multiwavelength observations from ...
