Epigenetic Regulation01:37

Epigenetic Regulation

4.2K
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.

Renewal of Skin Epidermal Stem Cells

3.2K
The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular...

Skin Cancer01:30

Skin Cancer

6.6K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

mTOR Signaling and Cancer Progression

5.1K
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.
The mTOR pathway or the...

Area of Science:

  • Molecular biology
  • Cancer research
  • Genetics

Background:

  • Melanoma pathogenesis is increasingly understood through molecular biology, with identified genetic alterations driving targeted therapy development.
  • Epigenetic factors, beyond genetic mutations, are recognized for their significant role in melanoma development and progression.

Purpose of the Study:

  • To review current data on epigenetic research in melanoma.
  • To highlight the implications of epigenetic alterations in melanoma.

Main Methods:

  • Review of microRNA (miRNA) expression profiling studies.
  • Analysis of DNA methylation profiling data.
  • Examination of histone modification research in melanoma.

Main Results:

  • miRNA expression profiling identified miRNAs regulating cell cycle, proliferation, migration, invasion, apoptosis, and immune response in melanoma.
  • Abnormal DNA methylation is linked to melanoma progression, with over 70 genes showing aberrant hypermethylation.
  • Histone modifications are increasingly recognized as central regulatory events in melanoma pathogenesis.

Conclusions:

  • Epigenetic biomarkers hold potential for diagnostic, prognostic, and therapeutic applications in melanoma.
  • Future melanoma treatment strategies may involve combining genetic and epigenetic biomarkers.
