Summary
This study used RNA-sequencing to find new biomarkers for prostate cancer (PCa) detection and prognosis. Key genes like BIRC5 and MKI67 show promise for improving early diagnosis and patient outcomes.
Area of Science:
- Oncology
- Genomics
- Bioinformatics
Background:
- Prostate cancer (PCa) remains a significant health concern for aging men.
- Current biomarkers for PCa detection and prognosis are insufficient.
- RNA-sequencing (RNA-seq) offers high sensitivity and accuracy for transcriptomic analysis.
Purpose of the Study:
- To identify novel RNA-seq-based biomarkers for prostate cancer (PCa) detection and prognosis.
- To analyze differentially expressed genes (DEGs) in medium-risk (MR) and high-risk (HR) PCa.
- To explore gene interactions and construct predictive models for PCa.
Main Methods:
- RNA-sequencing (RNA-seq) data analysis of PCa patient samples.
- Identification and functional enrichment analysis of differentially expressed genes (DEGs).
- Construction of a Protein-Protein Interaction (PPI) network and a nomogram model.
Main Results:
- 174 DEGs were shared between MR and HR PCa samples, involved in p53 signaling, nuclear division, and inflammation.
- Key genes (KIF20A, TPX2, BUB1, BIRC5, BUB1B, MKI67) showed increased expression with PCa progression.
- BIRC5, MKI67, and KIF20A identified as potential prognostic biomarkers; NIFK and PPP1CC as therapeutic targets.
Conclusions:
- Identified DEGs and key genes offer potential for improved PCa early detection and prognosis.
- The constructed nomogram model demonstrates prognostic value for identified biomarkers.
- New therapeutic targets (NIFK, PPP1CC) were proposed for PCa treatment.

RNA-seq
RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.

Ribosome Profiling
Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.

mTOR Signaling and Cancer Progression
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.
