Insights

Oestrogen receptors (ERs) ERα and ERβ have opposing roles in cell functions and cancer progression. Targeting ER subtype activity offers a promising therapeutic strategy for hormone-dependent cancers.

Area of Science:

  • Endocrinology
  • Molecular Biology
  • Oncology

Background:

  • Oestrogen receptors (ERs) ERα and ERβ mediate distinct cellular functions, including proliferation, apoptosis, and migration.
  • Dysregulation of ER subtype expression is observed in various cancers and correlates with clinical outcomes.
  • ERs play a critical role in the development and progression of hormone-dependent cancers.

Purpose of the Study:

  • To investigate the differential effects of ERα and ERβ on cellular processes relevant to cancer.
  • To explore the therapeutic potential of targeting ER subtype-specific activity in hormone-dependent cancers.

Main Methods:

  • Analysis of transcriptional responses elicited by ERα and ERβ.
  • Assessment of ER subtype expression patterns in cancer tissues.
  • Evaluation of the impact of ER bioavailability changes on tumor progression.

Main Results:

  • ERα and ERβ induce distinct transcriptional profiles, leading to opposing effects on cell proliferation, apoptosis, and migration.
  • Aberrant ER subtype expression is a hallmark of several cancer types, linked to patient prognosis.
  • Altered ER bioavailability in tumors influences cancer progression.

Conclusions:

  • ER subtype-specific modulation holds promise as a targeted therapeutic strategy for hormone-dependent cancers.
  • Understanding the distinct roles of ERα and ERβ is crucial for developing effective cancer treatments.

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 specific...

Role of ER in the Secretory Pathway

Eukaryotic cells have a special pathway that enables communication between various intracellular membrane-bound compartments and also with the extracellular environment. This pathway is termed as the secretory pathway.
Components of the secretory pathway
About a third of proteins synthesized in the cell are sorted via the secretory route. They shuffle between different compartments in membrane-bound vesicles until they reach their final destination. The main intracellular compartments involved...
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.
Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal01:22

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal

Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.

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...
