pH‐mediated activation of the lysosomal arginine sensor SLC38A9
FEBS Letters, EarlyView.Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Prothrombin-Sepharose-Purified Factor V and Its Role in Prothrombin Conversion
ASEAN Journal on Science and Technology for Development, 2017 Bovine Factor V isolated by the method of Esnouf and Jobin (1967) has been further purified by affiniy chromotgraphy through prothrombin-sepharose. Factor V bound quantitative to the prothrombin-sepharose column.

The human gut microbiome across the life course
FEBS Letters, EarlyView.Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

A general model for the CO–H2 conversion factor in galaxies with applications to the star formation law [PDF]
, 2011 The most common means of converting an observed CO line intensity into a molecular gas mass requires the use of a conversion factor (XCO). While in the Milky Way this quantity does not appear to vary significantly, there is good reason to believe that ...

Leśne Prace Badawcze, 2018 The aim of the study was to verify the commonly used conversion factors, their realignment and adaptation to current requirements for wood group S2. Our re-evaluation was based on medium-sized pine and spruce wood between 1 m and 3 m long, with an upper ...

Journal of Lipid Research, 1989 An HDL conversion factor which promotes the conversion of HDL3 to populations of larger and smaller particles has recently been identified in human plasma. In the present report a partially purified preparation of this factor has been used to examine the

FEBS Letters, EarlyView.Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

FEBS Letters, EarlyView.This study reveals that the small GTPase Rab14 is necessary for human papillomavirus (HPV) infection and plays an essential role in the transport of virions to the trans‐Golgi network (TGN). HPV in the early endosome (EE), which harbors GTP‐bound Rab14, is transported to the TGN through the switch of Rab14 from its GTP‐bound to GDP‐bound form.
