Summary
Protein arginine methyltransferase 1 (PRMT1) promotes chondrosarcoma growth by upregulating Yes-associated protein (YAP) activity. This study reveals PRMT1 as a potential therapeutic target for chondrosarcoma and other YAP-driven cancers.
Area of Science:
- Oncology
- Molecular Biology
- Cancer Research
Background:
- Protein arginine methyltransferase 1 (PRMT1) is an oncogene in various cancers.
- Yes-associated protein (YAP) is a key coactivator in Hippo signaling, crucial for tissue homeostasis and tumorigenesis.
- The roles of PRMT1 and YAP in chondrosarcoma remain unclear.
Purpose of the Study:
- To investigate the biological functions and prognostic value of PRMT1 and YAP in chondrosarcoma.
- To elucidate the underlying mechanisms of PRMT1 and YAP in chondrosarcoma development.
Main Methods:
- Analysis of PRMT1 and YAP expression in human chondrosarcoma specimens.
- Correlation analysis between PRMT1 levels, YAP nuclear accumulation, and clinicopathological features.
- In vitro and in vivo experiments involving PRMT1 overexpression and depletion.
- Mechanistic studies on the interaction between PRMT1, YAP, and LATS1.
Main Results:
- PRMT1 and YAP are upregulated in chondrosarcoma tissues.
- Elevated PRMT1 correlates with YAP nuclear accumulation, high-grade tumors, and poor prognosis.
- PRMT1 promotes chondrosarcoma cell growth via YAP-dependent mechanisms.
- PRMT1 suppresses LATS1-mediated YAP phosphorylation, enhancing cell survival.
Conclusions:
- PRMT1 acts as a positive regulator of YAP activity in chondrosarcoma.
- PRMT1 is an independent prognostic factor and a potential therapeutic target for chondrosarcoma.
- The PRMT1-YAP pathway offers a novel therapeutic strategy for YAP-driven cancers.

1.7K
The effective concentration of a species in a solution can be expressed precisely in terms of its activity. Activity considers the effect of electrolytes present in the vicinity of the species of interest and depends on the ionic strength of the solution. The activity of a species is expressed as the product of molar concentration and the activity coefficient of the species.
The thermodynamic equilibrium constant is more accurately defined in terms of activity rather than concentration.

To measure potential rates of soil extracellular enzyme activities, synthetic substrates that are bound to a fluorescent dye are added to soil samples. Enzyme activity is measured as the fluorescent dye is released from the substrate by an enzyme-catalyzed reaction, where higher fluorescence indicates more substrate...

Availability of somatic SCs is crucial for regenerative medicine, disease modeling and to gain insight into SC properties. Here we present experimental strategies to reprogram, in vitro, differentiated adult cells into their corresponding expandable tissue-specific stem/progenitor cells by the transient expression of the single transcriptional co-activator...

Gene transcription is regulated by the synergistic action of several proteins that form a complex at a gene regulatory site. This is observed in eukaryotes, where the regulation of gene expression is a complex process. Regulatory proteins in eukaryotes can broadly be classified into two types – regulators that bind directly to specific DNA sequences and co-regulators that associate with regulatory proteins but cannot directly bind to the DNA. These co-regulators are further divided into...

Aminoacyl-tRNA synthetases are present in both eukaryotes and bacteria. Though eukaryotes have 20 different aminoacyl-tRNA synthetases to couple to 20 amino acids, many bacteria do not have genes for all of these aminoacyl-tRNA synthetases. Despite this, they still use all 20 amino acids to synthesize their proteins. For instance, some bacteria do not have the gene encoding the enzyme that couples glutamine with its partner tRNA. In these organisms, one enzyme adds glutamic acid to all of the...

Activation energy is the minimum amount of energy necessary for a chemical reaction to move forward. The higher the activation energy, the slower the rate of the reaction. However, adding heat to the reaction will increase the rate, since it causes molecules to move faster and increase the likelihood that molecules will collide. The collision and breaking of bonds represents the uphill phase of a reaction and generates the transition state. The transition state is an unstable high-energy state...
