Figure Lengend Snippet: Fig. 1. Expression profiling of CEACAM7 in normal and cancerous tissues: (a) CEACAM7 in normal tissues: CEACAM7 is cell adhesion molecule 7 (Gene ID: 1087). According to BioProject (PRJEB4337) entitled ‘‘HPA RNA-seq normal tissues”, the expression level of CEACAM7 at normal condition in various tissue of human was showcased. This data was retrieved from the NCBI BioProject database. In this BioProject database, RNA-seq analysis was performed on normal tissue samples from 95 human individuals. This expression profiling clearly depicted that CEACAM7 does not express in most of the tissue in normal condition expect colon tissue. (b) Pan cancer gene expression of CEACAM7: The gene expression profile across all tumor samples and paired normal tissues is indicated in the dot plot. Each dot represents the expression of samples. The expression data was scaled by log2(TPM + 1). Red: Probable high tumor expression of CEACAM7; Green: Normal cell expression of CEACAM7. Source: GEPIA.

Figure Lengend Snippet: Fig. 2. (a) Differential gene expression box plot analysis of CEACAM7: GEPIA box plot analysis to observe significantly higher mRNA expression of CEACAM7 in PAAD followed by STAD. The red colored box is tumor tissue dataset and blue colored box is normal tissue dataset. Red * denoted significant data. The method for differential analysis is a one tailed unpaired student t-test, using disease state (tumor or normal) as a variable for calculating differential expression. The level of significance is p-value cutoff 0.01. (b) Protein expression level of CEACAM7: CPTAC analysis to observe mass-spectrometry-based proteomic characterization of CEACAM7 in various cancers. The statistics of each cancer indication are based on the Z-values, which denote standard deviations (SD) from the median value of all samples. The statistical significance p-value of normal vs Pancreatic adenocarcinoma (PAAD): 3.47e-04, normal vs colon cancer: 6.34e-18, normal vs Uterine corpus endometrial carcinoma (UCEC): 6.99e-02, normal vs Head and neck carcinoma (H&N Cancer): 4.03e-14.
