Insights

Sertraline and related renin-angiotensin system (RAS) drugs show anti-cancer effects against breast cancer cells. These compounds reduce cell viability and promote apoptosis, offering potential new strategies for breast cancer treatment.

Area of Science:

  • Oncology
  • Pharmacology
  • Molecular Biology

Background:

  • The renin-angiotensin system (RAS) is crucial for cardiovascular function but is implicated in cancer progression and metastasis.
  • Breast cancer, a leading cause of cancer mortality in women, presents ongoing prevention challenges.
  • RAS components are present in breast tissue, suggesting a role in cancer pathology.

Purpose of the Study:

  • To investigate the anti-cancer effects of sertraline, an antidepressant with known anti-proliferative properties.
  • To evaluate the impact of combining sertraline with RAS modulators (A779, Ang 1-7, losartan) on breast cancer cells.
  • To assess the effects on cell viability, apoptosis, and cell cycle distribution in MCF-7 cells.

Main Methods:

  • Treatment of MCF-7 breast cancer cells with sertraline, losartan, Ang 1-7, and A779, individually and in combination.
  • Assessment of cell viability, apoptosis induction, and cell cycle distribution.
  • Evaluation of reactive oxygen species (ROS) generation.

Main Results:

  • Sertraline, losartan, and Ang 1-7 significantly reduced MCF-7 cell viability and induced apoptosis and cell cycle arrest.
  • The RAS antagonist A779 diminished the effects of sertraline on cell viability, ROS generation, and cell cycle arrest.
  • Combination therapy with sertraline and losartan or Ang 1-7 resulted in a substantial decrease in cell viability.

Conclusions:

  • Sertraline exhibits anti-cancer properties against breast cancer cells.
  • Losartan and Ang 1-7 also demonstrate anti-cancer effects, acting via apoptosis and cell cycle arrest.
  • Targeting the RAS pathway in conjunction with sertraline may offer a promising therapeutic strategy for breast cancer.

Drugs Affecting GI Tract Motility: Serotonin Receptor Agonists

Serotonin, a crucial neurotransmitter synthesized by enterochromaffin cells, plays a cardinal role in regulating gastrointestinal (GI) motility. With over 90% of the body's total serotonin in the GI tract, its influence on digestive processes is profound. Serotonin is swiftly released upon various stimuli, such as food boluses or certain drugs, triggering intrinsic sensory neurons in the myenteric plexus and extrinsic vagal and spinal sensory neurons. This leads to the activation of the...

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...

Heart Failure Drugs: Inhibitors of Renin-Angiotensin System

The activation of the sympathetic nervous system and the renin-angiotensin-aldosterone system (RAAS) contributes to cardiac remodeling, and inhibiting the RAAS is a pharmacological target in heart failure management. As a result, neurohumoral modulation is a crucial treatment principle for managing heart failure. This approach involves using medications like ACE inhibitors (ACEIs), angiotensin receptor blockers (ARBs), β-blockers, mineralocorticoid receptor antagonists (MRAs), and neutral...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...
