Insights

MicroRNA-340 (miR-340) inhibits melanoma cell growth and tumorigenesis. This microRNA impacts RAS-RAF-Mitogen Activated Protein Kinase (MAPK) signaling, offering new insights into melanoma development.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • microRNA (miRNA)-dependent gene regulation is crucial in melanoma.
  • Understanding specific miRNA roles, like miR-340, is vital for melanoma research.

Purpose of the Study:

  • To investigate the function of miR-340 in human melanoma cells.
  • To explore miR-340's impact on melanoma cell tumorigenic properties.

Main Methods:

  • Cell-based assays were used to evaluate miR-340's effects.
  • Expression levels of MAPK pathway components were analyzed in relation to miR-340.

Main Results:

  • miR-340 was found to inhibit the tumorigenic phenotype of melanoma cells.
  • miR-340 modulates the expression of multiple components within the RAS-RAF-Mitogen Activated Protein Kinase (MAPK) signaling pathway.

Conclusions:

  • miR-340 plays an inhibitory role in melanoma progression.
  • The regulation of MAPK signaling by miR-340 provides insights into melanoma pathogenesis.

MAPK Signaling Cascades01:07

MAPK Signaling Cascades

Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...

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 Ras Gene02:38

The Ras Gene

The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family in humans constitutes three primary members—the HRas, NRas, and KRas. These genes code for four functionally distinct yet closely related proteins—the HRas, NRas, KRas4A, and KRas4B. The involvement of mutant Ras genes in human cancer was first discovered in 1982 and is among the most common causes of human tumorigenesis.

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...

MicroRNAs01:22

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...
