Regulation of Angiogenesis and Blood Supply

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl hydroxylase and factor...

Regulation of Hematopoietic Stem Cells

Regulation of Hematopoietic Stem Cells

All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...

Mitogens and the Cell Cycle

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...

Abnormal Proliferation

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...

Cancer-Critical Genes I: Proto-oncogenes

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...

Summary

Heat shock factor 1 (HSF1) is crucial for cell survival under stress. In cancer, HSF1 drives malignant transformation by promoting cell survival, altering metabolism, and suppressing metastasis, making it a potential therapeutic target.

Cellular Stress Response

Background:

Heat shock factor 1 (HSF1) is vital for the cellular acute response to proteotoxic stress.
HSF1 induces heat shock protein (HSP) gene transcription for cell survival and protein quality control.

Purpose of the Study:

To explore the multifaceted roles of HSF1 in cancer beyond its stress response function.
To understand how HSF1 contributes to malignant transformation and tumor progression.

Main Methods:

Review of recent studies on HSF1's function in various cancers.
Analysis of HSF1's roles as a transcription factor, signal modulator, and transcriptional repressor.

Main Results:

Chronically activated or overexpressed HSF1 is essential for multiple pathways in cancer.
HSF1 promotes cancer cell survival by reducing apoptosis and senescence.
HSF1 influences kinase activity, energy metabolism, and polyploidy in cancer cells.
HSF1 can cooperate with NuRD factors to repress metastasis-associated genes.

Conclusions:

HSF1 exhibits remarkable pleiotropy in cancer, acting as a key driver of malignancy.
HSF1's diverse functions highlight its potential as a therapeutic target in oncology.
Inhibitors targeting HSF1 are under development for cancer treatment.
