Rab14 regulates the transport of human papillomavirus to the trans‐Golgi network for infectious cell entry

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.

mTORC1 senses glutamine and other amino acids through GCN2

The EMBO Journal
mTORC1 promotes cell growth when nutrients such as amino acids are available. While dedicated sensors relaying availability of leucine, arginine and methionine to mTORC1 have been identified, it is still unclear how mTORC1 senses glutamine, one of its ...

Mechanisms of Ca2+/calmodulin-dependent kinase II activation in single dendritic spines

Nature Communications, 2019
Activation of Ca2+/calmodulin-dependent kinase II (CaMKII) in dendritic spines is a key step of long-term potentiation (LTP) induction, yet the exact biochemical steps of CaMKIIα activation in dendritic spines remained elusive. In this study, the authors

Mepazine Inhibits RANK-Induced Osteoclastogenesis Independent of Its MALT1 Inhibitory Function

Molecules, 2018
Mucosa-associated lymphoid tissue lymphoma translocation protein 1 (MALT1) is an intracellular cysteine protease (paracaspase) that plays an integral role in innate and adaptive immunity.

Phosphoinositides and inositol phosphates as molecular glues

FEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

CD157+ vascular endothelial cells derived from human-induced pluripotent stem cells have high angiogenic potential

Inflammation and Regeneration
Background We previously reported that a vascular endothelial stem cell population resides in pre-existing blood vessels in mice and may contribute to vascular endothelial cells in liver injury or hind limb ischemia models in the long-term.

Modelling stem cell differentiation related processes—A practical overview for biologists

FEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

APJ regulates the balance between self-renewal and differentiation of vascular endothelial stem cells

Inflammation and Regeneration
Background CD157 marks a population of tissue-resident vascular endothelial stem cells (VESCs) in mice known for their critical role in homeostatic endothelial cell (EC) turnover and the rapid response to vascular damage in the liver by regeneration ...

Indispensable role of Galectin-3 in promoting quiescence of hematopoietic stem cells

Nature Communications, 2021
Long term haematopoitic stem cells (LT-HSCs) are in a quiescent state during homeostasis, which is critical for their maintenance. Here, the authors show that Gal-3 expression in LT-HSCs is induced in response to Tie2 and Mpl and is both necessary and ...

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes

FEBS Letters, EarlyView.
GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.
