Cancer02:18

Cancer

Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
What is Cancer?02:12

What is Cancer?

Cells and tissues must meticulously coordinate their activities for the normal functioning of the human body. Therefore, they exhibit socially responsible behavior - resting, growing, dividing, differentiating, or dying - for the organism’s benefit. Cancer arises when cells divide uncontrollably and invade other tissues or organs.
Although people have known about cancer for centuries, it was only in 1761 that Giovanni Morgagni of Padua performed a detailed autopsy of patients who died from...

Cancer Therapies

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Cancer-Critical Genes II: Tumor Suppressor Genes01:05

Cancer-Critical Genes II: Tumor Suppressor Genes

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...

Area of Science:

  • Oncology
  • Molecular Biology
  • Iron Metabolism

Background:

  • Cellular iron is vital for cancer growth, angiogenesis, and metastasis.
  • Proteins like ferroportin, hepcidin, lipocalin 2, STEAP, and IRP families regulate iron homeostasis.
  • Their specific roles in cancer are increasingly understood.

Purpose of the Study:

  • To review recent insights into proteins regulating cellular iron in cancer.
  • To define the molecular mechanisms linking iron homeostasis to cancer progression.
  • To explore iron-dependent and independent effects of these proteins.

Main Methods:

  • Literature review of studies on iron-regulating proteins in cancer.
  • Analysis of research on ferroportin, hepcidin, lipocalin 2, STEAP, and IRP families.
  • Examination of evidence for iron modification and independent effects.

Main Results:

  • Proteins such as ferroportin and hepcidin play significant roles in cancer.
  • These proteins influence bioavailable iron, affecting tumor growth and metastasis.
  • Some proteins exhibit effects independent of their iron-regulatory functions.

Conclusions:

  • Iron homeostasis proteins are key regulators of cancer development.
  • Understanding these proteins offers new therapeutic targets for cancer treatment.
  • Further research is needed to elucidate both iron-dependent and independent mechanisms.
