Insights

New anticancer drugs target cell-cycle regulation, focusing on the mammalian target of rapamycin (mTOR) pathway. Inhibitors show promise for treating renal cell cancer by slowing tumor growth.

Area of Science:

  • Oncology
  • Molecular Biology
  • Pharmacology

Background:

  • Anticancer drug development focuses on cell-cycle regulation.
  • Mammalian target of rapamycin (mTOR) is crucial for cell growth and proliferation.
  • Rapamycin, an mTOR inhibitor, has demonstrated antitumor activity.

Purpose of the Study:

  • To investigate the role of mTOR pathway inhibitors in cancer treatment.
  • To evaluate the efficacy of mTOR inhibitors in renal cell cancer and other malignancies.

Main Methods:

  • Utilizing rapamycin and its analogues as mTOR inhibitors.
  • Conducting preclinical studies on human cancer cell lines.
  • Initiating clinical trials for various malignancies, including renal cell cancer.

Main Results:

  • Human cell lines, including renal cell cancer, exhibit sensitivity to mTOR inhibition.
  • Ongoing clinical trials are assessing mTOR inhibitors for multiple cancer types.
  • These agents primarily induce growth inhibition rather than tumor regression.

Conclusions:

  • The mTOR pathway is a viable target for anticancer therapies.
  • mTOR inhibitors represent a promising class of drugs for managing renal cell cancer and other tumors.
  • Current mTOR inhibitors are more effective at controlling tumor growth than causing regression.

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 rapamycin-insensitive companion...
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.

Inhibition of Cdk Activity02:34

Inhibition of Cdk Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...
Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against specific...
MAPK Signaling Cascades01:07

MAPK Signaling Cascades

Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...
