Epigenetic Regulation01:46

Epigenetic Regulation

28.7K
Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

Abnormal Proliferation02:23

Abnormal Proliferation

4.0K
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

5.7K
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.

Cancer Prevention02:59

Cancer Prevention

6.5K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Epigenetic Regulation01:37

Epigenetic Regulation

3.4K
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

Mutagenicity and Carcinogenicity01:25

Mutagenicity and Carcinogenicity

2.0K
Mutagenicity and carcinogenicity refer to the ability of drugs to cause genetic defects and induce cancer, respectively. The International Agency for Research on Cancer (IARC) classifies agents into four groups based on their carcinogenic potential. Group 1 agents are known human carcinogens; group 2A agents are probably carcinogenic to humans; group 3 agents lack data to support their role in carcinogenesis; and group 4 includes agents for which data support that they are not likely to be...

Summary

Epigenetic alterations in prostate cancer emerge early and are more prevalent than genetic defects. These changes offer promising biomarkers for diagnosis and potential therapeutic targets.

Area of Science:

  • Oncology
  • Genetics
  • Epigenetics

Background:

  • Prostate cancer is characterized by numerous genetic and epigenetic defects.
  • Epigenetic changes often precede genetic alterations during prostate cancer development.
  • The TMPRSS2-ETS fusion transcript is a common genetic defect influencing androgen signaling.

Purpose of the Study:

  • To explore the role of epigenetic alterations in prostate cancer pathogenesis.
  • To evaluate the potential of epigenetic changes as biomarkers for prostate cancer.
  • To discuss the therapeutic implications of epigenetic defects in prostate cancer.

Main Methods:

  • Review of existing literature on prostate cancer genetics and epigenetics.
  • Analysis of the prevalence and timing of epigenetic versus genetic alterations.
  • Examination of emerging technologies for detecting epigenetic marks and epigenetic drugs in clinical trials.

Main Results:

  • Epigenetic alterations are more common in prostate cancer than known genetic defects.
  • Epigenetic changes may play a role in the early stages of prostate carcinogenesis.
  • Somatic epigenetic alterations are central to new molecular biomarker development.
  • Epigenetic drugs are advancing through clinical trials for prostate cancer therapy.
