Insights

Molecular biology advances clarify renal cell carcinoma (RCC) development, particularly clear-cell type, linked to Von Hippel-Lindau (VHL) gene inactivation. Targeted therapies inhibiting VEGF and mTOR show promise for treating this kidney cancer.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Renal cell carcinoma (RCC) pathogenesis involves complex molecular events.
  • Inactivation of the Von Hippel-Lindau (VHL) tumor suppressor gene is crucial in clear-cell RCC development.
  • VHL loss leads to increased pro-angiogenic factors like VEGF and PDGF.

Purpose of the Study:

  • To review the molecular pathogenesis of inherited and sporadic RCC.
  • To discuss the role of VHL gene inactivation in RCC.
  • To highlight emerging targeted therapies for RCC.

Main Methods:

  • Review of current literature on RCC molecular biology.
  • Elucidation of molecular pathways in oncogenic transformation.
  • Analysis of targeted therapeutic strategies.

Main Results:

  • VHL gene inactivation is a key driver in clear-cell RCC.
  • VEGF and PDGF are significantly upregulated due to VHL loss.
  • Targeted therapies like anti-VEGF agents and mTOR inhibitors demonstrate clinical activity.

Conclusions:

  • Understanding RCC molecular pathways is advancing treatment options.
  • Targeted therapies offer new hope for RCC patients.
  • Further research into RCC pathogenesis can lead to improved therapies.

The Retinoblastoma Gene01:20

The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
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.

Metastasis02:30

Metastasis

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
Treatment Resistant Cancers02:56

Treatment Resistant Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...
Tumor Progression02:07

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
