Rous Sarcoma Virus (RSV) and Cancer01:03

Rous Sarcoma Virus (RSV) and Cancer

5.7K
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

The Retinoblastoma Gene01:20

The Retinoblastoma Gene

4.3K
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,...

Satellite Stem Cells and Muscular Dystrophy

2.1K
Satellite stem cells or myosatellite cells are quiescent stem cells that Alexander Mauro first identified in 1961. These cells are located between the sarcolemma, the plasma membrane of muscle fibers, and the basal lamina, the connective tissue sheath covering it. These mononucleated cells are activated in response to muscle injury, can transform into myoblasts, and may form or repair muscle fibers. Myosatellite cells can provide additional myonuclei for muscle regeneration or return to a...

Abnormal Proliferation02:23

Abnormal Proliferation

4.8K
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...

The Ras Gene02:38

The Ras Gene

6.7K
The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family in humans constitutes three primary members—the HRas, NRas, and KRas. These genes code for four functionally distinct yet closely related proteins—the HRas, NRas, KRas4A, and KRas4B. The involvement of mutant Ras genes in human cancer was first discovered in 1982 and is among the most common causes of human tumorigenesis.
Ras is a...

Area of Science:

  • Pediatric Oncology
  • Cancer Research
  • Clinical Trials

Background:

  • Rhabdomyosarcoma is a complex pediatric cancer with varied presentations.
  • Multimodality therapy has improved survival for low- and intermediate-risk patients.
  • Survival rates for metastatic rhabdomyosarcoma have not significantly improved.

Purpose of the Study:

  • To contrast North American and European treatment practices for rhabdomyosarcoma.
  • To identify areas for improved local control in high-risk rhabdomyosarcoma.
  • To highlight future research directions in rhabdomyosarcoma therapy.

Main Methods:

  • Review and comparison of Children's Oncology Group and International Society of Paediatric Oncology treatment protocols.
  • Analysis of current therapeutic principles including staging, surgery, radiation, and chemotherapy.
  • Identification of ongoing and planned clinical trials.

Main Results:

  • Core principles of rhabdomyosarcoma management (staging, surgery, radiation, chemotherapy) show similarity between North American and European approaches.
  • Current therapies have not overcome the survival deficit in metastatic rhabdomyosarcoma.
  • Research is exploring radiation dose escalation and delayed excision for higher-risk cases.

Conclusions:

  • Despite global similarities in rhabdomyosarcoma treatment foundations, outcomes for metastatic disease remain poor.
  • Future research focusing on radiation dose escalation, novel biomarkers, and targeted therapies holds promise for improving outcomes in high-risk and metastatic rhabdomyosarcoma.
  • Clinical trials are crucial for evaluating new strategies like proton therapy and imaging-based response assessment.
