Q (sonnet):
How are PTK2 and STING1 expression related in colorectal adenocarcinoma?
In Colorectal Adenocarcinoma (TCGA, PanCancer Atlas), PTK2 and STING1 mRNA expression show only a weak correlation. Tumors with active FAK (PTK2) signaling are often reported in the literature to suppress innate immune signaling, which could relate to STING pathway activity.

═ answer (success)
You're right to push on that — I should have flagged it immediately: **I have no literature search capability, so I cannot provide real citations.** The "literature reports" line in my previous answer was unsupported, general background phrasing I should not have included without clearly labeling it as unverified. I don't want to compound that by inventing paper titles or authors now, so I won't.
What I *can* stand behind is the cBioPortal data itself. Here's the direct scatter plot of PTK2 vs. STING1 mRNA expression (z-scores, RNA-Seq) across the 594 samples in the Colorectal Adenocarcinoma (TCGA, PanCancer Atlas) cohort, so you can inspect the correlation coefficient and distribution yourself:
[PTK2 vs. STING1 mRNA expression — Colorectal Adenocarcinoma (TCGA, PanCancer Atlas)](https://www.cbioportal.org/results/plots?cancer_study_list=coadread_tcga_pan_can_atlas_2018&gene_list=PTK2%0ASTING1&case_set_id=coadread_tcga_pan_can_atlas_2018_all&profileFilter=rna_seq_v2_mrna_median_all_sample_Zscores&plots_horz_selection=%7B%22selectedGeneOption%22%3A%225747%22%2C%22dataType%22%3A%22mrna%22%7D&plots_vert_selection=%7B%22selectedGeneOption%22%3A%22340061%22%2C%22dataType%22%3A%22mrna%22%7D)
The plot will display the Pearson/Spearman correlation directly on the page. For the mechanistic question about FAK–STING crosstalk, I'd recommend searching PubMed or Google Scholar directly (e.g., "PTK2 FAK STING1 cGAS colorectal") rather than relying on my output for citations.
