Number (%) of Primary Tumor Samples With Detectable mRNA Expression Determined by qRT-PCR.

𝑛 (%)	Prostate Normal 𝑛=7	Prostate Tumor 𝑛=30	Benign Prostatic Hypertrophy 𝑛=11	Normal Lymph Node and Spleen 𝑛=6	Lymphoma 𝑛=42	Colon Normal 𝑛=5	Colon Tumor 𝑛=42
MPL	0	1 (3)	0	0	0	0	0
EPOR	7 (100)	30 (100)	11 (100)	3 (50)	10 (24)	5 (100)	27 (64)
ERBB2	7 (100)	30 (100)	11 (100)	0	0	5 (100)	42 (100)
IGF1R	4 (57)	25 (83)	7 (64)	0	0	1 (20)	5 (12)

EPOR: erythropoietin receptor; ERBB2: human epidermal growth factor; IGF1R: insulin growth factor-1 receptor; MPL: thrombopoietin receptor; qRT-PCR: quantitative reverse transcription-polymerase chain reaction.
Detectable expression is determined by a normalized abundance ≥50.
