TEMPLATES: Direct Abundance Constraints for Two Lensed Lyman-break Galaxies

The Astrophysical Journal
Using integrated spectra for two gravitationally lensed galaxies from the JWST TEMPLATES Early Release Science program, we analyze faint auroral lines, which provide direct measurements of the gas-phase chemical abundance.

Co‐overexpression of the caloric restriction‐induced mitochondrial factors PGC‐1α and MIPEP upregulates Phospho1 expression in adipocytes

FEBS Open Bio, EarlyView.
Caloric restriction that extends lifespan induces the expression of PGC‐1α and MIPEP in white adipose tissue. In this study, co‐overexpression of Pgc‐1α and Mipep upregulated the gene expression of PHOSPHO1. These findings provide new insights into mitochondria‐related mechanisms underlying the effects of caloric restriction in adipocytes.

Chemical Abundances of Seven Stars in the GD-1 Stream

The Astrophysical Journal Letters
We present the first detailed chemical abundances for seven GD-1 stream stars from Subaru/High Dispersion Spectrograph spectroscopy. Atmospheric parameters were derived via color calibrations ( T _eff ) and iterative spectroscopic analysis.

Characterization of ribosome heterogeneity during endothelial to hematopoietic transition

FEBS Open Bio, EarlyView.
The panorama of ribosome heterogeneity during embryonic hematopoiesis has not yet been portrayed. In this study, utilizing dual‐omics data, the heterogenous dynamic of ribosome during endothelial‐to‐hematopoietic transition has been systemically described. Moreover, stage‐specific upregulation and peripheral localization of RPL27 and RACK1 in hemogenic

CD9‐association with PIP2 areas is regulated by a CD9 salt bridge

FEBS Open Bio, EarlyView.
The tetraspanin CD9 has an intracellular salt bridge. If CD9 opens, open‐CD9 moves from PIP2‐rich areas to regions populated by its interaction partner EWI‐2. Hence, the state of the salt bridge regulates the distribution of CD9 and by this CD9‐EWI‐2 complex formation.

Characterization of WAC interactions with R2TP and TTT chaperone complexes linking glucose and glutamine availability to mTORC1 activity

FEBS Open Bio, EarlyView.
TTT and R2TP chaperone complexes are required for the assembly and activation of mTORC1. WAC directly interacts with components of TTT, R2TP, and mTORC1, and these interactions are affected by the availability of glucose and glutamine, correlating with changes in mTORC1 activity.
