miR-1 and miR-122 levels are negatively correlated in human liver cancer. Scatterplot and linear regression of miR-122 and miR-1 levels in liver cancer patients. The LIHC-TCGA data downloaded from UCSC Xena Cancer browser (xenabrowser.net) was plotted and linear regression coefficients were calculated using the lm() function in R. Overall regression coefficient between miR-122 and miR-1 was calculated as −0.212 (p-value = 1.22 × 107). Data was further stratified by G6PD mRNA levels (high = dark blue, low = light blue). Individual coefficients and p-values were calculated for each condition using the lm() function in R and are shown on the plot. Density plots were used to visualize the distribution of miR-1 (top panel) and miR-122 (right panel) levels in the context of G6PD mRNA levels. Kolmogorov–Smirnov test was used to calculate significant differences in the relative distribution of miRNA and G6PD mRNA levels (miR-122 p-value = 1.94 × 10−8, miR-1 p-value = 0.09263).
