Abstract

Insights

Src family kinases (SFKs) are crucial in cancer. This study found c-Src, not c-Yes, is key in malignant skin cancers like melanoma and SCC, driving their progression.

Area of Science:

  • Oncology
  • Molecular Biology
  • Dermatology

Background:

  • Src family kinases (SFKs) are implicated in cancer development, including proliferation, survival, and metastasis.
  • c-Src and c-Yes are frequently over-expressed in human epithelial cancers.
  • Limited research exists on c-Src and c-Yes roles in cutaneous carcinomas.

Purpose of the Study:

  • To determine the expression patterns of c-Src and c-Yes in malignant melanoma (MM), squamous cell carcinoma (SCC), and basal cell carcinoma (BCC).
  • To elucidate the specific roles of c-Src and c-Yes in the pathogenesis of these skin cancers.

Main Methods:

  • Western blotting was used to analyze c-Src and c-Yes expression in normal skin and tumor tissues.
  • Immunohistochemical staining was performed on MM, SCC, and BCC specimens to evaluate protein localization and expression.
  • A total of 18 malignant skin tumor tissues and 48 specific carcinoma specimens were analyzed.

Main Results:

  • c-Src expression was detected in all malignant skin tumors but absent in normal skin.
  • c-Yes was expressed in MM and SCC, but notably absent in BCC and normal skin.
  • Immunohistochemistry results corroborated the western blot findings for both c-Src and c-Yes.

Conclusions:

  • c-Src plays a significant role in the proliferation and progression of malignant skin cancers.
  • c-Yes appears to have a less prominent role compared to c-Src in the studied cutaneous carcinomas.
  • Targeting c-Src may offer a therapeutic strategy for managing aggressive skin cancers.

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).
Somatic cells are...
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 daughter...

Rous Sarcoma Virus (RSV) and Cancer

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...
Cancer-Critical Genes I: Proto-oncogenes01:33

Cancer-Critical Genes I: Proto-oncogenes

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...
