Abstract

Insights

Growth Regulation by Estrogen (GREB1) is a key gene in hormone-driven cancers like breast and prostate. Understanding GREB1's role may lead to new therapeutic strategies targeting cancer progression.

Area of Science:

  • Oncology
  • Molecular Biology
  • Endocrinology

Background:

  • Steroid hormones significantly influence cancer incidence and progression.
  • Estrogen exposure increases risks for breast, ovarian, and endometrial cancers.
  • Mechanisms of hormone-stimulated cancer growth require further elucidation for novel therapies.

Purpose of the Study:

  • To review the role of the Growth Regulation by Estrogen 1 (GREB1) gene.
  • To examine GREB1 as a mediator of estrogen and androgen signaling in cancer.

Main Methods:

  • Literature review of studies on GREB1 function.
  • Analysis of GREB1's role in hormone-stimulated cell proliferation.

Main Results:

  • GREB1 is induced by steroid hormones.
  • GREB1 mediates estrogen-stimulated breast cancer cell proliferation.
  • GREB1 mediates androgen-stimulated prostate cancer cell proliferation.

Conclusions:

  • GREB1 is a critical mediator in hormone-driven cancers.
  • GREB1 modulates tumor progression in breast, ovarian, and prostate cancer models.
  • GREB1 is a potential therapeutic target for endocrine resistance and cancer treatment.

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...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

G Protein-coupled Receptors01:15

G Protein-coupled Receptors

G Protein-Coupled Receptors or GPCRs are membrane-bound receptors that transiently associate with heterotrimeric G proteins and induce an appropriate response to sensory stimuli such as light, odors, hormones, cytokines, or neurotransmitters.
GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...

Transducer Mechanism: Enzyme-Linked Receptors

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:

Treatment Resistant Cancers02:56

Treatment Resistant Cancers

Cancer is the second leading cause of death in the United States. A cancer cell is genetically unstable and hence can mutate faster. They can also modify their microenvironment and escape immune surveillance. The difficulties in treating cancer are further compounded by the emergence of rapid resistance to anticancer drugs. The most common ways to attain resistance in cancer cells include alteration in drug transport and metabolism, modification of drug target, elevated DNA damage response, or...

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...
