Abstract

BTG2/TIS21/PC3 protein is involved in the regulation of G1/S transition of the cell cycle by inhibiting pRb function, suggesting that BTG2/TIS21/PC3 regulation is critical for normal cell growth and proliferation. To understand the regulatory mechanisms for the expression of BTG2/TIS21/PC3 we cloned the human gene. Potential binding sites for several transcription factors were identified in the 5'-flanking region of the gene. Transient expression assays with BTG2/TIS21/PC3 promoter deletions and electrophoretic mobility shift analysis identified a major wild-type p53 response element located -74 to -122 relative to the start codon. This genomic fragment was sufficient to constitute a promoter element in the presence of p53. The BTG2/TIS21/PC3 gene is an antiproliferative gene which maps within a chromosomal segment (1q32) frequently altered in breast adenocarcinomas. However, no mutations of BTG2/TIS21/PC3 were detected in breast cancer cells, suggesting that the inactivation of this gene is not a frequent genetic event during breast carcinogenesis.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
