Insights

Targeting the mechanistic target of rapamycin (mTOR) pathway and Y-box-protein 1 (YB-1) shows promise for treating gynecological cancers. Dual targeting may improve outcomes where mTOR inhibition alone has failed.

Area of Science:

  • Oncology
  • Molecular Biology
  • Gynecologic Oncology

Background:

  • Mechanistic (mammalian) target of rapamycin (mTOR) signaling is implicated in gynecological cancers.
  • Elevated mTOR pathway activity correlates with poorer prognosis in these cancers.
  • Current mTOR-targeted therapies show limited efficacy in gynecological malignancies.

Purpose of the Study:

  • To review recent clinical and basic science findings on the interplay between mTOR signaling and cold shock proteins in gynecological cancers.
  • To explore the potential of dual targeting of mTOR and Y-box-protein 1 (YB-1) for improved anti-cancer activity.

Main Methods:

  • Literature review of clinical results and basic research.
  • Analysis of molecular pathways and protein interactions.

Main Results:

  • Dual targeting of mTOR and Y-box-protein 1 (YB-1) demonstrates potential for inhibiting carcinogenic activity.
  • Y-box-protein 1 (YB-1) impacts AKT and downstream mTOR interactors like EGFR, Snail, and E-cadherin.
  • Several mTOR pathway components are differentially expressed in ovarian, endometrial, and cervical cancers.

Conclusions:

  • Y-box-protein 1 (YB-1) is a key player in the mTOR pathway within gynecological cancers.
  • Combined targeting of mTOR and YB-1 offers a promising strategy for gynecological cancer treatment.
  • Further investigation into downstream actors connecting mTOR and YB-1 is warranted.

PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...

Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as  SH2...

Negative Regulator Molecules01:23

Negative Regulator Molecules

Positive regulators allow a cell to advance through cell cycle checkpoints. Negative regulators have an equally important role as they terminate a cell’s progression through the cell cycle—or pause it—until the cell meets specific criteria.
