Summary
Protein arginine methyltransferase 2 (PRMT2) promotes renal cell cancer (RCC) progression by enhancing WNT5A expression. High PRMT2 and WNT5A levels correlate with poor outcomes, suggesting their potential as biomarkers and therapeutic targets in RCC.
Area of Science:
- Oncology
- Molecular Biology
- Epigenetics
Background:
- Protein arginine methyltransferase 2 (PRMT2) regulates gene expression and histone methylation.
- PRMT2's role in renal cell cancer (RCC) progression is not well understood.
- Previous studies linked PRMT2 to breast cancer and glioblastoma.
Purpose of the Study:
- To investigate the role of PRMT2 in renal cell cancer (RCC).
- To explore the molecular mechanisms underlying PRMT2's function in RCC.
- To evaluate PRMT2 and WNT5A as potential biomarkers for RCC.
Main Methods:
- Analysis of PRMT2 expression in RCC tissues and cell lines.
- In vitro and in vivo experiments to assess the impact of PRMT2 overexpression on RCC cell proliferation and motility.
- Chromatin immunoprecipitation (ChIP) assays to determine PRMT2's effect on H3R8me2a enrichment at the WNT5A promoter.
- Quantitative real-time PCR (qRT-PCR) to measure WNT5A transcriptional expression.
- Correlation analysis between PRMT2/WNT5A expression and clinicopathological features in RCC patients.
Main Results:
- PRMT2 was significantly upregulated in primary RCC and RCC cell lines.
- PRMT2 overexpression enhanced RCC cell proliferation and motility.
- PRMT2 mediated H3R8 asymmetric dimethylation (H3R8me2a) at the WNT5A promoter, increasing WNT5A transcription.
- Activation of Wnt signaling via PRMT2/WNT5A axis promoted RCC progression.
- High PRMT2 and WNT5A expression correlated with adverse clinicopathological characteristics and poorer overall survival in RCC patients.
Conclusions:
- PRMT2 overexpression drives RCC progression through the WNT5A/Wnt signaling pathway.
- PRMT2 and WNT5A are potential predictive diagnostic biomarkers for RCC metastasis.
- PRMT2 represents a novel therapeutic target for RCC treatment.

3.8K
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.

8.8K
The gene encoding the main signaling molecules of the Wnt signaling pathways (the Wnt proteins) was discovered almost four decades ago by Nüsslein-Volhard and Wieschaus. They identified and originally named the gene "wingless" (wg) after a phenotype discovered during their landmark genetic screen in Drosophila for body pattern defects. At around the same time, another researcher named Harold Varmus found that a murine tumor virus activates the mammalian wg homolog, Int-1, which...

7.3K
Wnt is a zygotic effect gene that is expressed during very early embryonic development. It regulates various processes in animals starting from early development through the adult stage, such as organogenesis in the embryo and maintenance of neuronal and blood stem cells. Wnt proteins can induce a wide variety of intracellular pathways depending upon the specific abilities of different Wnt ligands to form a complex with shared and cognate receptors in the presence of different co-receptors. The...

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...

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

4.6K
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...
