Histone deacetylases (HDACs) in XPC gene silencing and bladder cancer

Table 4 Determination of the presence of the HDAC4 in both normal and cancerous bladder tissues from bladder tumor tissue arrays.

Type of bladder tissues	# of HDAC4(+)	# of Total tissues	% of HDAC4(+)
Normal bladder tissues	1	23	4.3
Transitional cell carcinomas (Grade 1)	26	58	44.8
Transitional cell carcinomas (Grade 2)	28	59	47.5
Transitional cell carcinomas (Grade 3)	8	25	32.0
P value	p ^Δ < 0.001
	p^σ = 0.08

Note: p ^Δ value is the comparison between the group of normal bladder tissues and the group of cancerous bladder tissues. p^σ is the comparison among the groups of normal bladder tissues, Grade 1, Grade 2, and Grade 3 bladder carcinomas.
