Abstract

Insights

Grape seed proanthocyanidins extract (GSPE) inhibits pancreatic cancer cell growth and migration. This effect is partly mediated by down-regulating miR-27a expression and up-regulating FOXO1.

Area of Science:

  • Oncology
  • Molecular Biology
  • Natural Products Chemistry

Background:

  • Pancreatic cancer remains a significant health challenge with limited effective treatments.
  • Grape seed proanthocyanidins extract (GSPE) is a natural compound with potential anti-cancer properties.
  • Understanding the molecular mechanisms of GSPE action is crucial for developing novel therapeutic strategies.

Purpose of the Study:

  • To investigate the inhibitory effects of GSPE on pancreatic cancer cell growth.
  • To elucidate the underlying molecular mechanisms, focusing on miR-27a and FOXO1.
  • To assess the impact of GSPE on cell proliferation, apoptosis, and migration.

Main Methods:

  • In vitro culture of AsPC-1 pancreatic cancer cells.
  • Assessment of cell proliferation, apoptosis, and migration using MTT, Annexin V-FITC/PI, and Transwell assays.
  • Quantification of miR-27a and FOXO1 expression via real-time RT-PCR and Western blot.
  • Validation of miR-27a's role using miR-27a inhibitors.

Main Results:

  • GSPE demonstrated dose-dependent inhibition of pancreatic cancer cell growth, significantly above 50 μg/mL.
  • GSPE induced apoptosis and suppressed cell migration.
  • GSPE significantly down-regulated miR-27a expression and up-regulated FOXO1 expression.
  • Combined GSPE and miR-27a inhibitor treatment showed enhanced inhibition of growth and migration.

Conclusions:

  • GSPE exhibits anti-proliferative and anti-migratory effects on AsPC-1 pancreatic cancer cells.
  • The observed effects are partly attributed to the down-regulation of miR-27a and up-regulation of FOXO1.
  • GSPE represents a potential therapeutic agent for pancreatic cancer, warranting further investigation.

MicroRNAs

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...

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.

Cancer Prevention02:59

Cancer Prevention

Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.
