CD9

Across TCGA patient cohorts, CD9 RNA expression is significantly associated with the protein abundance of many other proteins, with 12,535 significant associations in total. LSCC shows the largest number of these associations.

The most reproducible CD9-associated proteins across cancer lineages are KRT19, PLEKHA5, and CTNND1. Each is linked with CD9 in more than 5 cancer types. Because this analysis shows association rather than direction, both CD9-to-partner and partner-to-CD9 results are reported.

Each partner links to its own Q-omics profile. The scatter plot shows the strongest example, CD9 versus KRT19 in HNSC, with a Pearson correlation of 0.54.

RNA expression associated proteins by consensus

Ranked by combined sampling and lineage consensus. X-score (CD9→partner) and Y-score (partner→CD9) are standardized regression coefficients; both directions are reported because the association is undirected. p-values are from the association test.

Lineage	Partner protein	X-score	Y-score	p(X)	p(Y)	Sampling consensus	Lineage consensus
HNSC	KRT19 →	+1.208	+1.069	<.001	<.001	3	6
HNSC	PLEKHA5 →	+0.482	+1.139	<.001	.003	3	5
HNSC	CTNND1 →	+0.231	+0.959	<.001	<.001	3	5
BRCA	KIAA1217 →	+0.391	+0.697	<.001	<.001	3	5
BRCA	ACAP1 →	-0.497	-0.489	.003	.008	3	4
HNSC	PHB2 →	+0.296	+0.936	<.001	<.001	3	4

Each partner links to its Q-omics profile. Showing the 6 strongest of 12,535 associations by consensus.
