PKC𝜶 and ER𝜷 Are Associated with Triple-Negative Breast Cancers in African American and Caucasian Patients

Table 2

(a) PKCα expression is similar in African American and Caucasian patients. (b) ERβ expression and subcellular localization is similar in African American and Caucasian patients.

(a)

Outcome	Median (minimum, maximum)		𝑃 value*
	AA	Caucasian
PKCα (freq)	2 (0,4)	2 (0,4)	0.46
PKCα (int)	2 (0,4)	1 (0,4)	0.52
PKCα (sum)	4 (0,8)	4 (0,8)	0.49

* 𝑃 value based on the Wilcoxon rank-(sum) test.

(b)

Outcome	Median (minimum, maximum)		𝑃 value*
	AA	Caucasian
ERβ freq(n)	2 (0, 4)	2 (0, 4)	1.00
ERβ int (n)	1 (0, 4)	1 (0, 4)	0.76
ERβ freq (c)	3 (1, 4)	3 (2, 4)	0.83
ERβ int (c)	1 (1, 3)	1 (1, 4)	0.84

* 𝑃 value based on Wilcoxon rank-Sum test. n: nuclear; c: cytoplasmic.
