RBM12 Maintains Glioma Stem Cells by Activating Amino Acid‐Dependent mTORC1 Signaling via SLC7A5 mRNA Stabilization

Advanced Science, EarlyView.
This study shows that in glioma stem cells (GSCs), RBM12 recruits ALKBH5 to remove m6A from SLC7A5 transcripts, thereby enhancing mRNA stability, which elevates large neutral amino acid (LNAA) levels and activates mTORC1, promoting GSC proliferation, self‐renewal, and tumor growth.

Slc44a2 Deficiency Unveils an IFN‐I–Dependent Feedback Control of pDC Egress

Advanced Science, EarlyView.
Working model of SLC44A2‐mediated maintenance of pDC homeostasis. This model illustrates two central mechanisms by which SLC44A2 regulates pDC homeostasis: (1) SLC44A2 limits IFN‐I production by exporting amino acids (T, N, Q), thereby preventing spontaneous pDC activation.

GPCR signaling inhibits mTORC1 via PKA phosphorylation of Raptor

eLife, 2019
The mammalian target of rapamycin complex 1 (mTORC1) regulates cell growth, metabolism, and autophagy. Extensive research has focused on pathways that activate mTORC1 like growth factors and amino acids; however, much less is known about signaling cues ...

A role for BDNF- and NMDAR-induced lysosomal recruitment of mTORC1 in the regulation of neuronal mTORC1 activity

Molecular Brain, 2021
Memory and long term potentiation require de novo protein synthesis. A key regulator of this process is mTORC1, a complex comprising the mTOR kinase. Growth factors activate mTORC1 via a pathway involving PI3-kinase, Akt, the TSC complex and the GTPase ...

Regulation of mTORC1 Signaling by pH

PLoS ONE, 2011
Acidification of the cytoplasm and the extracellular environment is associated with many physiological and pathological conditions, such as intense exercise, hypoxia and tumourigenesis. Acidification affects important cellular functions including protein synthesis, growth, and proliferation.

mTORC1 maintains metabolic balance [PDF]

Cell Research, 2015
Anticancer therapeutics aimed at the inhibition of mTORC1 activity shift metabolism to favor the degradation of extracellular proteins. Recently Thompson and colleagues demonstrated a novel regulatory mechanism whereby mTORC1 plays a distinct role as a key regulator of metabolism depending on the environmental nutrient status.

Targeting the ATX‐LPA Axis Overcomes TKI Resistance and Immunosuppression in Renal Cell Carcinoma via Dual Inhibition of AKT/mTOR and TBK1/IRF3 Pathways

Advanced Science, EarlyView.
ABSTRACT Background Therapeutic resistance limits durable survival in advanced/metastatic renal cell carcinoma (RCC) treated with first‐line tyrosine kinase inhibitor (TKI) plus immune checkpoint inhibitor (ICI). We sought to define key resistance drivers and actionable targets.

Depletion of Flot1 attenuates macropinosome-dependent mTORC1 activation in podocytes

Cell Structure and Function
Podocytes are terminally differentiated renal epithelial cells that play a crucial role in kidney filtration. Given this essential function, podocyte dysfunction results in kidney diseases known as podocytopathies. Previous studies have demonstrated that

mTORC1 Signaling Is Palmitoylation-Dependent in Hippocampal Neurons and Non-neuronal Cells and Involves Dynamic Palmitoylation of LAMTOR1 and mTOR

Frontiers in Cellular Neuroscience, 2019
The mechanistic target of rapamycin (mTOR) Complex 1 (mTORC1) controls growth and proliferation of non-neuronal cells, while during neuronal development mTORC1 responds to glutamate and neurotrophins to promote neuronal migration and dendritic ...
