MicroRNA-1911-3p targets mEAK-7 to suppress mTOR signaling in human lung cancer cells.

Regulation of mTOR signaling depends on an intricate interplay of post-translational protein modification. Recently, mEAK-7 (mTOR associated protein, eak-7 homolog) was identified as a positive activator of mTOR signaling via an alternative mTOR complex. However, the upstream regulation of mEAK-7 in human cells is not known.

Palliative Care in a Community-Based Serious-Illness Care Program.

Although community-based serious-illness care (CBSC) is an innovative care model, it is unclear to what extent CBSC addresses palliative care needs, particularly for those patients near death. To evaluate palliative care services of a CBSC program. Retrospective chart reviews.

mEAK-7 Forms an Alternative mTOR Complex with DNA-PKcs in Human Cancer.

MTOR associated protein, eak-7 homolog (mEAK-7), activates mechanistic target of rapamycin (mTOR) signaling in human cells through an alternative mTOR complex to regulate S6K2 and 4E-BP1. However, the role of mEAK-7 in human cancer has not yet been identified. We demonstrate that mEAK-7 and mTOR signaling are strongly elevated in tumor and metastatic lymph nodes of patients with non-small-cell lung carcinoma compared with those of patients with normal lung or lymph tissue.

Mammalian EAK-7 activates alternative mTOR signaling to regulate cell proliferation and migration.

Nematode EAK-7 (enhancer-of--1-7) regulates dauer formation and controls life span; however, the function of the human ortholog mammalian EAK-7 (mEAK-7) is unknown. We report that mEAK-7 activates an alternative mechanistic/mammalian target of rapamycin (mTOR) signaling pathway in human cells, in which mEAK-7 interacts with mTOR at the lysosome to facilitate S6K2 activation and 4E-BP1 repression. Despite interacting with mTOR and mammalian lethal with SEC13 protein 8 (mLST8), mEAK-7 does not interact with other mTOR complex 1 (mTORC1) or mTOR complex 2 (mTORC2) components; however, it is essential for mTOR signaling at the lysosome.
