Cancer Survival Analysis

Cancer Survival Analysis

Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...

Cancer-Critical Genes II: Tumor Suppressor Genes

Cancer-Critical Genes II: Tumor Suppressor Genes

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

Purpose of the Study:

Introduce StickWRLD, a novel visualization tool for data exploration.
Enable researchers to identify significant correlations and filter irrelevant ones.
Improve the process of feature selection in complex datasets.

Main Methods:

Developed StickWRLD for visual data browsing and correlation analysis.
Implemented dynamic modification of retention parameters (P and r).
Applied StickWRLD to a semi-synthetic dataset derived from human data.

Main Results:

StickWRLD effectively displays all possible correlations within a dataset.
The tool allows for rapid identification of significant correlations.
Successfully detected low-penetrance gene-SNP correlations missed by conventional methods.

Conclusions:

StickWRLD offers an efficient method for navigating complex datasets.
The tool enhances the ability to make informed decisions about statistical model adequacy.
StickWRLD facilitates the discovery of previously undetected biological relationships.
