Abstract

Insights

Circular RNA circHIPK3 promotes prostate cancer (PCa) progression and metastasis by regulating the miR-448/MTDH axis. This finding suggests circHIPK3 as a potential therapeutic target for PCa treatment.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Prostate cancer (PCa) is a leading cancer diagnosis in men globally.
  • Circular RNAs (circRNAs) play a significant role in PCa's biological processes.
  • Understanding circRNA mechanisms is vital for PCa progression and metastasis research.

Purpose of the Study:

  • Investigate the molecular mechanism of circHIPK3 in prostate cancer.
  • Determine the role of circHIPK3 in PCa progression and metastasis.
  • Explore circHIPK3 as a potential therapeutic target for PCa.

Main Methods:

  • RNA interference and overexpression vectors were used to manipulate circHIPK3 and MTDH levels.
  • Luciferase reporter assays assessed interactions between circHIPK3, miR-448, and MTDH.
  • MTT, colony formation, and Transwell assays evaluated PCa cell proliferation and migration.

Main Results:

  • circHIPK3 levels were elevated in PCa tissues and cell lines.
  • Overexpression of circHIPK3 enhanced PCa cell migration, proliferation, and invasion.
  • circHIPK3 promoted MTDH expression by sponging miR-448, and enhanced tumor growth in vivo.

Conclusions:

  • circHIPK3 exhibits carcinogenic effects in PCa by modulating the miR-448/MTDH pathway.
  • circHIPK3 represents a potential therapeutic target for prostate cancer.
  • Further research into circHIPK3's role could lead to novel PCa treatments.

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.

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...

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...

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...

Experimental RNAi02:15

Experimental RNAi

RNA interference (RNAi) is a cellular mechanism that inhibits gene expression by suppressing its transcription or activating the RNA degradation process. The mechanism was discovered by Andrew Fire and Craig Mello in 1998 in plants. Today, it is observed in almost all eukaryotes, including protozoa, flies, nematodes, insects, parasites, and mammals. This precise cellular mechanism of gene silencing has been developed into a technique that provides an efficient way to identify and determine the...
