Abstract

Insights

MicroRNA-25 (miR-25) promotes Renal Cell Carcinoma (RCC) progression by downregulating ADAMTS16 and activating the Wnt/β-catenin pathway. Inhibiting miR-25 reduces RCC cell viability and migration, offering potential therapeutic targets.

Area of Science:

  • Oncology
  • Molecular Biology
  • Biochemistry

Background:

  • MicroRNAs (miRNAs) are key regulators of tumor growth.
  • Renal Cell Carcinoma (RCC) progression is influenced by various molecular mechanisms.
  • The specific role of miR-25 in RCC requires further elucidation.

Purpose of the Study:

  • To investigate the contribution of miR-25 to Renal Cell Carcinoma (RCC) progression.
  • To identify the molecular targets and pathways regulated by miR-25 in RCC.
  • To explore the potential of targeting miR-25 for RCC treatment.

Main Methods:

  • Examined miR-25 and ADAMTS16 expression in RCC tissues and cell lines.
  • Validated miR-25 targeting of ADAMTS16 using luciferase reporter assays.
  • Assessed cell viability, apoptosis, migration, and invasion via CCK-8 and flow cytometry.
  • Analyzed protein expression of ADAMTS16, β-catenin, GSK-3β, and p-GSK-3β using western blot.

Main Results:

  • miR-25 expression was significantly elevated in RCC tissues.
  • ADAMTS16 was identified as a direct target of miR-25, with higher miR-25 correlating to lower ADAMTS16 levels.
  • Overexpression of miR-25 enhanced RCC cell viability and migration while suppressing apoptosis.
  • miR-25 promoted Wnt/β-catenin pathway activation by phosphorylating GSK-3β and β-catenin.

Conclusions:

  • miR-25 promotes RCC progression by downregulating ADAMTS16.
  • The Wnt/β-catenin signaling pathway is implicated in miR-25-mediated RCC development.
  • miR-25 represents a potential therapeutic target for Renal Cell Carcinoma.

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...

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.

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...

The Retinoblastoma Gene01:20

The Retinoblastoma Gene

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Induced Pluripotent Stem Cells01:06

Induced Pluripotent Stem Cells

Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).

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...
