Insights

Circular RNA NEK11 (circNEK11) is upregulated in hepatocellular carcinoma (HCC), promoting tumor growth and recurrence. circNEK11 may serve as a diagnostic biomarker and therapeutic target for HCC.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Circular RNAs (circRNAs) play regulatory roles in cancers.
  • The specific function of circNEK11 in hepatocellular carcinoma (HCC) is not well understood.

Purpose of the Study:

  • Investigate the role and mechanism of circNEK11 in HCC progression.
  • Determine circNEK11's potential as a biomarker for HCC.

Main Methods:

  • Quantified circNEK11 expression in HCC tissues.
  • Studied circNEK11's interaction with YTHDC1 and miR-1236-3p.
  • Assessed circNEK11's impact on HCC cell functions in vitro and in vivo.

Main Results:

  • circNEK11 expression is significantly upregulated in HCC, particularly in recurrent cases.
  • circNEK11 promotes HCC cell proliferation, migration, and tumor growth.
  • circNEK11 directly targets miR-1236-3p, regulating GPX2 expression and promoting HCC progression.

Conclusions:

  • circNEK11 acts as an oncogenic circRNA in HCC by regulating the miR-1236-3p/GPX2 axis.
  • circNEK11 is a potential diagnostic biomarker and therapeutic target for HCC.

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...

Epigenetic Regulation

Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

Epigenetic Regulation

Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

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).
