Abstract

Insights

Circular RNA (circRNA) circSLC19A1 is upregulated in prostate cancer (PCa). Silencing circSLC19A1 inhibits PCa progression by regulating the miR-326/MAPK1 axis, offering a potential therapeutic target for PCa.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Circular RNAs (circRNAs) are increasingly recognized for their regulatory roles in cancer.
  • Prostate cancer (PCa) is a significant area of research within oncology.
  • CircSLC19A1 has emerged as a specific circRNA of interest for its potential involvement in PCa pathogenesis.

Purpose of the Study:

  • To investigate the role and mechanism of circSLC19A1 in prostate cancer (PCa).
  • To explore the regulatory relationship between circSLC19A1, miR-326, and MAPK1 in PCa cells.

Main Methods:

  • Quantitative real-time PCR (qRT-PCR) to assess gene expression levels.
  • RNase R treatment to confirm circRNA identification.
  • Dual-luciferase reporter assays to validate binding interactions.
  • Cellular assays including CCK-8, colony formation, wound healing, and Transwell assays to evaluate cell behavior.

Main Results:

  • CircSLC19A1 expression was significantly upregulated in PCa tissues and cells.
  • Silencing circSLC19A1 suppressed PCa cell viability, proliferation, migration, and invasion.
  • A regulatory axis involving circSLC19A1, miR-326, and MAPK1 was identified, with circSLC19A1 positively correlating with MAPK1 and negatively with miR-326.

Conclusions:

  • CircSLC19A1 acts as an oncogenic circRNA in prostate cancer.
  • CircSLC19A1 silencing inhibits PCa cell proliferation, migration, and invasion.
  • The findings highlight the circSLC19A1/miR-326/MAPK1 pathway as a potential therapeutic target for PCa treatment.

Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

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...

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...

Inhibition of Cdk Activity02:34

Inhibition of Cdk Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

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...
