Insights

Renal cell carcinoma (RCC) targeted therapies show promise but face resistance. This review explores novel molecular targets to improve treatment outcomes for this rising cancer.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Renal cell carcinoma (RCC) incidence is increasing, with over 58,000 new cases in the US.
  • Traditional RCC treatments like chemotherapy, radiation, and cytokine therapy have limited efficacy.
  • Molecularly targeted therapies have improved RCC care, but challenges like resistance and toxicity persist.

Purpose of the Study:

  • To review emerging therapeutic targets for renal cell carcinoma.
  • To discuss advancements in understanding RCC's molecular biology.
  • To identify potential new treatment strategies beyond current therapies.

Main Methods:

  • Literature review of recent studies on RCC molecular pathways.
  • Analysis of established and novel therapeutic targets.
  • Discussion of VHL/HIF axis, PI3K/AKT/mTOR pathway, and synthetic lethality screens.

Main Results:

  • Several promising therapeutic targets are under investigation for RCC.
  • Understanding molecular pathways like VHL/HIF and PI3K/AKT/mTOR is crucial.
  • Synthetic lethality screens are identifying novel drug targets.

Conclusions:

  • Further research into novel molecular targets is essential for overcoming RCC treatment resistance.
  • Targeted therapies hold significant potential to improve outcomes for renal cell carcinoma patients.
  • Personalized treatment strategies based on molecular profiling may enhance efficacy and reduce toxicity.

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.

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...

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...

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
