Summary
Long non-coding RNA CRNDE promotes cervical cancer growth and progression. Targeting CRNDE and PUMA may offer new therapeutic strategies for cervical cancer.
Area of Science:
- Oncology
- Molecular Biology
- Genetics
Background:
- Cervical cancer is a major global health concern for women.
- Long non-coding RNAs (lncRNAs) are implicated in cancer development.
- The role of lncRNA CRNDE in cervical cancer is largely unknown.
Purpose of the Study:
- To investigate the clinical significance of CRNDE expression in human cervical cancer.
- To elucidate the functional role of CRNDE in cervical cancer cell proliferation and tumorigenicity.
- To explore the underlying molecular mechanism of CRNDE in cervical cancer progression.
Main Methods:
- Quantitative real-time PCR to measure CRNDE expression in tissues and cell lines.
- Loss-of-function (knockdown) and gain-of-function (overexpression) experiments in cervical cancer cells.
- In vivo tumorigenicity assays in a mouse model.
- Western blotting and co-immunoprecipitation to confirm the interaction between CRNDE and PUMA.
Main Results:
- CRNDE expression is significantly upregulated in cervical cancer tissues and cell lines.
- CRNDE knockdown inhibits, while overexpression promotes, cervical cancer cell proliferation and growth in vitro.
- CRNDE knockdown suppresses, while overexpression enhances, cervical cancer tumorigenicity in vivo.
- CRNDE directly binds to PUMA, and this interaction is crucial for CRNDE-mediated promotion of cervical cancer cell growth.
Conclusions:
- CRNDE plays a critical role in promoting cervical cancer progression.
- The CRNDE-PUMA axis is a potential therapeutic target for cervical cancer.
- CRNDE and PUMA may serve as biomarkers for clinical diagnosis and prognosis of cervical cancer.

9.8K
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...

03:03mTOR Signaling and Cancer Progression
4.7K
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.

02:35Chromatin Position Affects Gene Expression
24.7K
Chromatin is the massive complex of DNA and proteins packaged inside the nucleus. The complexity of chromatin folding and how it is packaged inside the nucleus greatly influences access to genetic information. Generally, the nucleus' periphery is considered transcriptionally repressive, while the cell's interior is considered a transcriptionally active area.

195.1K
Overview
Gene expression is the process in which DNA directs the synthesis of functional products, that is, proteins. Cells can regulate gene expression at various stages. It allows organisms to generate different cell types and enables cells to adapt to internal and external factors.
Genetic Information Flows from DNA to RNA to Protein
A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is made up of nucleotides and proteins consist of amino...

01:32RNA Splicing
60.4K
Splicing is the process by which eukaryotic RNA is edited before its translation into protein. The RNA strand transcribed from eukaryotic DNA is called the primary transcript. The primary transcripts that become mRNAs are called precursor messenger RNAs (pre-mRNAs). Eukaryotic pre-mRNA contains alternating sequences of exons and introns. Exons are nucleotide sequences that code for proteins, whereas introns are the non-coding regions. In RNA splicing, introns are removed and exons are bonded...

02:36RNA Polymerase II Accessory Proteins
10.8K
Proteins that regulate transcription can do so either via direct contact with RNA Polymerase or through indirect interactions facilitated by adaptors, mediators, histone-modifying proteins, and nucleosome remodelers. Direct interactions to activate transcription is seen in bacteria as well as in some eukaryotic genes. In these cases, upstream activation sequences are adjacent to the promoters, and the activator proteins interact directly with the transcriptional machinery. For example, in...
