1. How to obtain list of top differentally expressed genes?


Step 1: Go to analysis page of UALCAN and choose cancer of interest from left panel by clicking it.

Step 2: UALCAN lists top 250 over-/under-expressed genes in cancer of interest compared to normal samples.

Step 3: User can analyze gene expression and survival profiles of individual gene by clicking the on the heat map.

Step 4: UALCAN also enables user to view top 250 over-/under-expressed genes in major cancer subtypes compared to normal samples.

2. How to query UALCAN for gene(s) of interest in specific cancer?


Step 1: Go to analysis page of UALCAN and enter offical symbol of gene(s) in the text area


Step 2: Choose the TCGA data set of interest from the drop down menu and click "Explore" button to submit.

Step 3: Output page provides links to analysis results and external database links.

a. How to explore expression profile of gene of interest based on clinico-pathologic factors?


Obtaining EZH2 expression profile in breast invasive carcinoma dataset based on patient’s race.

Downloading the box plot from UALCAN

b. How to obtain Kaplan meier plot from UALCAN?


Analyzing survival plots of EZH2 in breast invasive carcinoma TCGA dataset

c. How to obtain promoter DNA methylation level from UALCAN?


Analyzing promoter DNA methylation level of THSD1 in breast invasive carcinoma TCGA dataset

d. How to obtain list of positive and negatively correlated genes from UALCAN?


Obtaining list of positively/negatively correlated genes of EZH2 in breast invasive carcinoma TCGA dataset

3. How to obtain expression and survival profile for pre-compiled gene classes?

Step 1: Go to analysis page of UALCAN

Step 2: Query UALCAN for pre-compiled gene classes

Step 3: Select gene class of interest (e.g. Kinase coding genes) and click "Explore" to see results

Step 4: UALCAN lists all kinase coding genes and indicates their expression status and survival effect in different cancers.


Cancer with red border show up regulation of gene



Cancer with green border show down regulation of gene


Step 5: User can click on any of these link to visualize expression and survival profiles
