Hepatocellular carcinoma: An analysis of the expression status of stress granules and their prognostic value

Figure 2 Risk grouping construction based on The Cancer Genome Atlas-Liver Hepatocellular Carcinoma, GSE25097, and GSE36376 combined datasets. A: Least absolute shrinkage and selection operator is a gradient descent method for determining hub genes; B: Number of hub genes and their corresponding coefficients; C: Train group samples were classified into high- and low-risk groups based on the risk scores. Red indicates high-risk group samples, and blue indicates low-risk group samples; D: Test group samples have been classified into high-risk and low-risk groups based on the risk scores. Red indicates high-risk group samples, and blue indicates low-risk group samples; E: The hub genes expression within the high- and low-risk groups of the train group. Red indicates up-regulated expression, blue indicates under-expression of the expression, and white indicates zero expression; F: The hub genes expression within high- and low-risk groups of the test group. Red indicates up-regulated expression, blue indicates under-expression of the expression, and white indicates zero expression.
