Insights

Gerbil skin cells, when exposed to a carcinogen, become resistant to differentiation. This resistance suggests gerbil skin

Area of Science:

  • Dermatology
  • Carcinogenesis
  • Cell Biology

Background:

  • Gerbil skin exhibits unresponsiveness to two-stage carcinogenesis.
  • Understanding the cellular mechanisms underlying this resistance is crucial for cancer research.

Purpose of the Study:

  • To investigate the cellular basis of gerbil skin's resistance to chemical carcinogenesis.
  • To determine the effect of a carcinogen initiator on gerbil epidermal cell behavior.

Main Methods:

  • Adult gerbil epidermal cells were treated with 3-methylcholanthrene (a carcinogen) both in vivo and in vitro.
  • The differentiation response of treated cells to calcium induction was assessed.

Main Results:

  • Carcinogen treatment resulted in gerbil epidermal cells that were resistant to calcium-induced terminal differentiation.
  • This finding aligns with models of skin carcinogenesis in mice, where initiation alters epidermal differentiation programs.

Conclusions:

  • Initiation of carcinogenesis in gerbils involves altered epidermal differentiation.
  • Gerbil skin's resistance to two-stage carcinogenesis is likely linked to the promotion stage of the process.

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...
Replicative Cell Senescence02:15

Replicative Cell Senescence

Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds the telomeric...
Renewal of Skin Epidermal Stem Cells01:12

Renewal of Skin Epidermal Stem Cells

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 cells,...

Distinctive Features of Adult Stem Cells vs Cancer Stem Cells

A stem cell is an unspecialized cell that can divide without limit as needed and can, under specific conditions, differentiate into specialized cells.
Adult stem cells
Adult stem cells are tissue-specific; hence, they divide to develop the tissue from which they originate. One type of adult stem cell is the epithelial stem cell, which gives rise to the keratinocytes in the multiple layers of epithelial cells in the epidermis of the skin. Adult bone marrow has three distinct types of stem cells:...
Mutagenicity and Carcinogenicity01:25

Mutagenicity and Carcinogenicity

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...

Cellular Adaptation IV: Dysplasia and Metaplasia

DysplasiaDysplasia refers to abnormal changes in the size, shape, and organization of mature cells, characterized by pleomorphism, nuclear abnormalities, and increased mitotic activity. It commonly affects epithelial tissues, including the cervix, gastrointestinal tract, respiratory mucosa, and endometrium. Although it may occur alongside hyperplasia, dysplasia is not a true adaptive response but a preneoplastic change with potential to progress to cancer.When confined above the basement...
