Table I. Classification of transcript patterns in SW837 cells in response to butyrate.

(A) Forty two sequences found to be potentially paused by the “5′ 3′ array” and the “Tiling” array were classified according to NaB effect throughout the canonical coding region. Up and Down indicate upregulation and downregulation, respectively (>1.5-fold change), while NS indicates no significant change in response to butyrate. Examples of each category are shown in Figure 5.

	Coding region
Category	5′ end	middle	3′ end	Sequences (%)
I	UP	UP	NS	47.6
	UP	DOWN	NS	2.4
	UP	UP/DOWN	DOWN	2.4
II	NS	DOWN	DOWN	21.4
	NS	UP	NS	16.7
	NS	DOWN	NS	9.5
