Summary

This summary is machine-generated.

Long noncoding RNA HIF1A-AS2 promotes cervical cancer (CC) progression by activating c-Jun and sponging miR-34b-5p, making it a potential therapeutic target. This study reveals HIF1A-AS2's oncogenic role in CC.

Area Of Science

  • Molecular Oncology
  • RNA Biology
  • Cancer Genomics

Background

  • Long noncoding RNAs (lncRNAs) play roles in cancer, but HIF1A-AS2 mechanisms in cervical cancer (CC) are unclear.
  • HIF1A-AS2 is upregulated in various human cancers, suggesting a role in tumor progression.

Purpose Of The Study

  • Investigate the expression pattern of HIF1A-AS2 in cervical cancer.
  • Elucidate the molecular mechanisms and signaling pathways involving HIF1A-AS2 in CC.

Main Methods

  • Assessed HIF1A-AS2 transcript levels in 20 CC patient specimens and 3 CC cell lines using qRT-PCR.
  • Performed functional assays (CCK-8, Transwell, Apoptosis) and utilized bioinformatics databases (JASPAR, miRDB, Targetscan).
  • Validated interactions using dual luciferase assays, ChIP, and RIP experiments.

Main Results

  • HIF1A-AS2 expression was significantly elevated in CC tissues and cell lines.
  • HIF1A-AS2 knockdown inhibited proliferation and invasion while inducing apoptosis; overexpression had opposite effects.
  • Identified c-Jun as a transcription factor activating HIF1A-AS2 and confirmed HIF1A-AS2 acts as a molecular sponge for miR-34b-5p, targeting radixin (RDX).

Conclusions

  • c-Jun-activated HIF1A-AS2 functions as an oncogenic factor in CC by sponging miR-34b-5p to regulate radixin.
  • HIF1A-AS2 presents a promising therapeutic target for cervical cancer treatment.

lncRNA - Long Non-coding RNAs 02:39

8.4K

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...

Rous Sarcoma Virus (RSV) and Cancer 01:03

4.9K

Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

Non-LTR Retrotransposons 03:18

As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...

Induced Pluripotent Stem Cells 01:06

3.9K

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).

Cancer-Critical Genes I: Proto-oncogenes 01:33

8.6K

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

Abnormal Proliferation 02:23

4.4K

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...
