Insights

Alterations in DNA, RNA, and histone methylation are key to keratinocyte cancers (KCs). Understanding cross-talk between these methylation processes may reveal new therapeutic strategies for these common cancers.

Area of Science:

  • Oncology
  • Epigenetics
  • Molecular Biology

Background:

  • Keratinocyte cancers (KCs), including basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (cSCC), are the most common human cancers.
  • Dysregulation of methylation processes (DNA, RNA, histone) is implicated in KC pathogenesis.
  • The intricate cross-talk between these distinct methylation pathways in KCs is an emerging area of research.

Purpose of the Study:

  • To synthesize current findings on the role of DNA, RNA, and histone methylation alterations in KC development.
  • To explore the molecular mechanisms underlying methylation dysregulation in KCs.
  • To highlight potential therapeutic strategies emerging from the understanding of methylation cross-talk in KCs.

Main Methods:

  • Literature review and synthesis of recent evidence.
  • Analysis of molecular and mechanistic changes in KC pathogenesis related to methylation.
  • Exploration of cross-talk between different methylation processes.

Main Results:

  • Gene expression disruption via altered DNA, RNA, and histone methylation is critical in KC pathogenesis.
  • Methylation modifiers are frequently dysregulated in KCs, but underlying mechanisms are still being elucidated.
  • Significant cross-talk exists among DNA, RNA, and histone methylation processes in KCs.

Conclusions:

  • Understanding the interplay of methylation processes offers novel therapeutic avenues for KCs.
  • Targeting methylation pathways presents a promising strategy for treating BCC and cSCC.
  • Further research into methylation cross-talk is crucial for advancing KC therapies.

Epigenetic Regulation

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

Epigenetic Regulation01:37

Epigenetic Regulation

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.

Skin Cancer01:30

Skin Cancer

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...

Induced Pluripotent Stem Cells01:06

Induced Pluripotent Stem Cells

Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).

Abnormal Proliferation02:23

Abnormal Proliferation

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...

Mitogens and the Cell Cycle02:38

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...
