Insights

Carvacrol, a TRPM7 inhibitor, effectively reduced prostate cancer cell growth, migration, and invasion. This suggests carvacrol

Area of Science:

  • Oncology
  • Molecular Biology
  • Pharmacology

Background:

  • Prostate cancer remains a significant health concern with limited therapeutic options.
  • Transient Receptor Potential Melastatin 7 (TRPM7) is implicated in prostate cancer progression.
  • Identifying novel therapeutic targets like TRPM7 is crucial for effective treatment strategies.

Purpose of the Study:

  • To investigate the therapeutic potential of carvacrol, a TRPM7 inhibitor, against prostate cancer.
  • To evaluate the effects of carvacrol on prostate cancer cell proliferation, migration, and invasion.
  • To elucidate the underlying molecular mechanisms of carvacrol's action in prostate cancer cells.

Main Methods:

  • Utilized nonselective TRPM7 inhibitor carvacrol on human prostate cancer cell lines (PC-3 and DU145).
  • Assessed cell proliferation, migration, and invasion assays.
  • Measured TRPM7-like currents, protein expression (MMP-2, p-Akt, p-ERK1/2), and F-actin reorganization.
  • Performed TRPM7 knockdown experiments for comparative analysis.

Main Results:

  • Carvacrol inhibited TRPM7-like currents in prostate cancer cells.
  • Carvacrol significantly reduced cell proliferation, migration, and invasion.
  • Carvacrol decreased MMP-2, p-Akt, and p-ERK1/2 protein levels and disrupted F-actin.
  • TRPM7 knockdown mirrored the inhibitory effects of carvacrol on cancer cell behavior.

Conclusions:

  • Carvacrol demonstrates therapeutic potential for prostate cancer treatment.
  • Inhibition of TRPM7 channels by carvacrol suppresses key cancer hallmarks.
  • Carvacrol's efficacy is linked to the suppression of PI3K/Akt and MAPK signaling pathways.

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.

PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a...

Cancer Vaccines01:30

Cancer Vaccines

Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

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...

Cancer Cell Migration through Invadopodia01:35

Cancer Cell Migration through Invadopodia

Invadosome is a broad category of cell surface structures with proteolytic activity that  degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...
