Moderate nuclear/nucleolar immunoreactivity was observed in most cancer tissues. Few melanomas, squamous cell carcinomas and liver cancers were strongly stained. Several carcinoids, lymphomas, prostate and renal cancers were weakly stained or negative.
Most tumour cells showed weak to moderate cytoplasmic and/or nuclear immunoreactivity. Cases of breast, stomach and liver cancers showed cases with strong staining.
Transcription of protein-coding genes can be reconstituted on naked DNA with only the general transcription factors and RNA polymerase II. However, this minimal system cannot transcribe DNA packaged into chromatin, indicating that accessory factors may facilitate access to DNA. One such factor, FACT (facilitates chromatin transcription), interacts specifically with histones H2A/H2B to effect nucleosome disassembly and transcription elongation. FACT is composed of an 80 kDa subunit and a 140 kDa subunit; this gene encodes the 140 kDa subunit. [provided by RefSeq, Feb 2009]
