Bipartite binding and partial inhibition links DEPTOR and mTOR in a mutually antagonistic embrace

open access: yeseLife, 2021
The mTORC1 kinase complex regulates cell growth, proliferation, and survival. Because mis-regulation of DEPTOR, an endogenous mTORC1 inhibitor, is associated with some cancers, we reconstituted mTORC1 with DEPTOR to understand its function.

Research advances of cell autophagy in focal segmental glomerulosclerosis

open access: yesLinchuang shenzangbing zazhi
As a clinical pathological syndrome, focal segmental glomerulosclerosis (FSGS) is characterized by focal glomerulosclerosis, disappearance of podocyte processes and massive proteinuria. Current researches have confirmed that foot cell injury is a central

mTOR hyperactivity mediates lysosomal dysfunction in Gaucher's disease iPSC-neuronal cells

open access: yesDisease Models & Mechanisms, 2019
Bi-allelic GBA1 mutations cause Gaucher's disease (GD), the most common lysosomal storage disorder. Neuronopathic manifestations in GD include neurodegeneration, which can be severe and rapidly progressive.

Influenza virus differentially activates mTORC1 and mTORC2 signaling to maximize late stage replication. [PDF]

open access: yesPLoS Pathogens, 2017
Influenza A virus usurps host signaling factors to regulate its replication. One example is mTOR, a cellular regulator of protein synthesis, growth and motility.

TAK1-dependent autophagy: A suppressor of fatty liver disease and hepatic oncogenesis. [PDF]

open access: yes, 2014
In addition to regulating the activation of nuclear factor (NF)-κB and c-Jun N-terminal kinase (JNK), TGF-β activated kinase 1 (TAK1) also upregulates the activation of AMP-activated protein kinase (AMPK) and autophagy.

TARDBP/TDP-43 regulates autophagy in both MTORC1-dependent and MTORC1-independent manners [PDF]

open access: yesAutophagy, 2016
In a recent paper we addressed the mechanism by which defective autophagy contributes to TARDBP/TDP-43-mediated neurodegenerative disorders. We demonstrated that TARDBP regulates MTORC1-TFEB signaling by targeting RPTOR/raptor, a key component and an adaptor protein of MTORC1.

Screen for chemical modulators of autophagy reveals novel therapeutic inhibitors of mTORC1 signaling. [PDF]

open access: yesPLoS ONE, 2009
BACKGROUND:Mammalian target of rapamycin complex 1 (mTORC1) is a protein kinase that relays nutrient availability signals to control numerous cellular functions including autophagy, a process of cellular self-eating activated by nutrient depletion ...

PIP4kγ is a substrate for mTORC1 that maintains basal mTORC1 signaling during starvation [PDF]

open access: yesScience Signaling, 2014
A feedback loop involving PIP4kγ and mTORC1 maintains basal mTORC1 activity under nutrient-deprived conditions.

Hippo pathway at the crossroads of stemness and therapeutic resistance in breast cancer

open access: yesMolecular Oncology, EarlyView.
Dysregulation of the Hippo pathway drives nuclear accumulation of YAP/TAZ, activating stemness‐related transcriptional programs that sustain breast cancer stemness and fuel therapeutic resistance across subtypes, underscoring Hippo signaling as a targetable vulnerability. Figure created and edited with BioRender.com.

The yin yang of sunitinib: One drug, two doses, and multiple outcomes

open access: yesMolecular & Cellular Oncology, 2017
Our recent work showed that sunitinib exerts dual effect on cancer cells in different dose ranges. In clinically relevant doses, cancer cells tolerate sunitinb cytotoxicity by upregulating pro-survival MCL-1 and activating mTORC1 signaling. Inhibition of
