Abstract

Insights

Long noncoding RNA DDX11-AS1 promotes glioma progression by activating the miR-1183/E2F7 pathway. This finding highlights DDX11-AS1 as a potential therapeutic target for treating this lethal brain malignancy.

Area of Science:

  • Oncology
  • Molecular Biology
  • Genetics

Background:

  • Glioma is a lethal primary brain malignancy with a poor prognosis.
  • The role of long noncoding RNA (lncRNA) DDX11-AS1 in glioma pathogenesis requires further investigation.
  • DDX11-AS1 has known oncogenic functions in other cancer types.

Purpose of the Study:

  • To characterize the oncogenic role of DDX11-AS1 in glioma.
  • To elucidate the molecular mechanism by which DDX11-AS1 contributes to glioma progression.

Main Methods:

  • Analyzed DDX11-AS1 expression in clinical glioma specimens and public datasets.
  • Investigated the functional impact of DDX11-AS1 on glioma cell proliferation and migration using in vitro knockdown and overexpression.
  • Assessed in vivo tumor growth in orthotopic glioma mouse models.
  • Performed competitive endogenous RNA (ceRNA) analysis to identify regulatory axes involving DDX11-AS1, miR-1183, and E2F7.
  • Conducted functional rescue experiments via miR-1183 inhibition.

Main Results:

  • DDX11-AS1 expression was significantly upregulated in clinical glioma specimens.
  • DDX11-AS1 knockdown suppressed glioma cell proliferation and migration in vitro, while overexpression enhanced these phenotypes.
  • In vivo studies confirmed DDX11-AS1 drives glioma tumor growth.
  • DDX11-AS1 acts as a ceRNA by interacting with miR-1183.
  • miR-1183 inhibition rescued the effects of DDX11-AS1 knockdown on glioma phenotypes and restored E2F7 expression.

Conclusions:

  • lncRNA DDX11-AS1 promotes glioma progression through the miR-1183/E2F7 axis.
  • DDX11-AS1 represents a potential therapeutic target for glioma treatment.

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...

lncRNA - Long Non-coding RNAs

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

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 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...
