Hello! I'm Rui Wang. Thank you for stopping by my site.

During the day, I am a student at USTS.My research interests are bioinformatics.I'm also interested in more applied problems with nice theoretical components.I'm a serial side project maker. In the last 3 years, I've started 13 side projects in many different areas. Few are wildly popular. Many are dead. Several of them are still hanging around today.

Thank you for stopping by! I would love to learn what brought you here. I want to hear your stories, your interests, and your questions.You can contact me through email

A ferroptosis-related gene signature identified as a novel prognostic biomarker for colon cancer

Frontiers in Genetics .

  • Background: Colon cancer (CC) is a common gastrointestinal malignant tumor with high heterogeneity in clinical behavior and response to treatment, making individualized survival prediction challenging. Ferroptosis is a newly discovered iron-dependent cell death that plays a critical role in cancer biology. Therefore, identifying a prognostic biomarker with ferroptosis-related genes provides a new strategy to guide precise clinical decision-making in CC patients.
  • Methods: Alteration in the expression profile of ferroptosis-related genes was initially screened in GSE39582 dataset involving 585 CC patients. Univariate Cox regression analysis and LASSO-penalized Cox regression analysis were combined to further identify a novel ferroptosis-related gene signature for overall survival prediction. The prognostic performance of the signature was validated in the GSE17536 dataset by Kaplan-Meier survival curve and time-dependent ROC curve analyses. Functional annotation of the signature was explored by integrating GO and KEGG enrichment analysis, GSEA analysis and ssGSEA analysis. Furthermore, an outcome risk nomogram was constructed considering both the gene signature and the clinicopathological features.
  • Results: The prognostic signature biomarker composed of 9 ferroptosis-related genes accurately discriminated high-risk and low-risk patients with CC in both the training and validation datasets. The signature was tightly linked to clinicopathological features and possessed powerful predictive ability for distinct clinical subgroups. Furthermore, the risk score was confirmed to be an independent prognostic factor for CC patients by multivariate Cox regression analysis ( p value < 0.05). Functional annotation analyses showed that the prognostic signature was closely correlated with pivotal cancer hallmarks, particularly cell cycle, transcriptional regulation, and immune-related functions. Moreover, a nomogram with the signature was also built to quantify outcome risk for each patient.
  • Conclusion: The novel ferroptosis-related gene signature biomarker can be utilized for predicting individualized prognosis, optimizing survival risk assessment and facilitating personalized management of CC patients.
  • Development of a novel chemokine signaling-based multigene signature to predict prognosis and therapeutic response in colorectal cancer

    Zhejiang University-SCIENCE B .

  • Colorectal cancer (CRC) is the most lethal gastrointestinal cancer in both males and females worldwide (Sung et al., 2021). Because of the high heterogeneity of tumors, robust prognostic biomarkers are urgently needed in CRC management (Koncina et al., 2020). Chemokine signaling is a well-known pivotal player in immunity, inflammation, and cancer metastasis (Lacalle et al., 2017; Poeta et al., 2019; Do et al., 2020), and multiple genes involved in chemokine signaling have been demonstrated as potential prognostic biomarkers for CRC (Cabrero-De Las Heras and Martínez-Balibrea, 2018; Ottaiano et al., 2020; Yu et al., 2020). Therefore, the aim of our study was to develop a chemokine signaling-based multigene signature (CSbMgSig) that could effectively predict overall survival (OS) and therapeutic response for patients with CRC.

    Construction and analysis of the ferroptosis-related risk model predicting prognosis of colon cancer
  • To construct a ferroptosis-related prognostic risk model for overall survival prediction in colon cancer, the present study first downloaded 260 ferroptosis-related genes from the public FerrDb database. Then, differentially expressed ferroptosis-related genes were identified based on the GSE39582 dataset containing 585 patients with colon cancer. LASSO-penalized Cox regression analysis was used to construct a ferroptosis-related gene signature to predict the overall survival of colon cancer patients. The prognostic performance of the signature was validated in the GSE17536 dataset. The results showed that the constructed prognostic model could accurately discriminate high-risk and low-risk patients with colon cancer in both the training and validation datasets. The model possessed powerful predictive ability for distinct clinical subgroups, and was confirmed to be an independent prognostic factor for colon cancer patients. Functional annotation analyses showed that the prognostic signature was closely correlated with pivotal cancer hallmarks, e.g. cell cycle and immune-related functions, and patients in the high-risk group were more sensitive to anticancer drugs. Additionally, the nomogram constructed based on this model and clinical information exhibited good predictive ability. In conclusion, the constructed model can be used to predict the prognosis of colon cancer patients, and is beneficial to guide the clinical treatment of colon cancer.
