ATP-dependent chromatin-remodeling complexes are known to facilitate transcriptional activation by opening chromatin structures. We report a novel human complex, named NURD, which contains not only ATP-dependent nucleosome disruption activity, but also histone deacetylase activity, which usually associates with transcriptional repression. The deacetylation(More)
We present evidence that both corepressors SMRT and N-CoR exist in large protein complexes with estimated sizes of 1.5-2 MDa in HeLa nuclear extracts. Using a combination of conventional and immunoaffinity chromatography, we have successfully isolated a SMRT complex and identified histone deacetylase 3 (HDAC3) and transducin (beta)-like I (TBL1), a WD-40(More)
A large-scale community survey in Shatin, Hong Kong, is presented with a modified two-phase design using flagged and nonflagged subsamples. A modified Self-Reporting Questionnaire and the Diagnostic Interview Schedule (version III) were used as the screening and diagnostic instruments, respectively. Lifetime rates for 19 Diagnostic Interview(More)
In sexual transmission of simian immunodeficiency virus, and early and later stages of human immunodeficiency virus-type 1 (HIV-1) infection, both viruses were found to replicate predominantly in CD4(+) T cells at the portal of entry and in lymphoid tissues. Infection was propagated not only in activated and proliferating T cells but also, surprisingly, in(More)
Acetylation of core histone tails plays a fundamental role in transcription regulation. In addition to acetylation, other posttranslational modifications, such as phosphorylation and methylation, occur in core histone tails. Here, we report the purification, molecular identification, and functional characterization of a histone H4-specific methyltransferase(More)
OBJECTIVE To evaluate the current knowledge on the risk factors for recurrence, efficacy of adjuvant therapy in preventing recurrence, and the optimal management of recurrence after resection of hepatocellular carcinoma (HCC). SUMMARY BACKGROUND DATA The long-term prognosis after resection of HCC remains unsatisfactory as a result of a high incidence of(More)
BACKGROUND Most patients with acute biliary pancreatitis have stones in the biliary tract or ampulla of Vater. Because these stones may be passed spontaneously soon after a patient is admitted to the hospital, the importance of early operative removal is not known. We tested the hypothesis that endoscopic papillotomy within 24 hours of admission decreased(More)
Adaptive radiation therapy is a closed-loop radiation treatment process where the treatment plan can be modified using a systematic feedback of measurements. Adaptive radiation therapy intends to improve radiation treatment by systematically monitoring treatment variations and incorporating them to re-optimize the treatment plan early on during the course(More)
A heparin-binding mitogen was isolated from conditioned medium of human embryonic lung fibroblasts. It exhibited broad target-cell specificity whose pattern was distinct from that of any known growth factor. It rapidly stimulated tyrosine phosphorylation of a 145-kDa protein in responsive cells, suggesting that its signaling pathways involved activation of(More)
OBJECTIVE This study aimed to evaluate the long-term results of treatment and prognostic factors in patients with intrahepatic recurrence after curative resection of hepatocellular carcinoma (HCC). SUMMARY BACKGROUND DATA Recent studies have demonstrated the usefulness of re-resection, transarterial oily chemoembolization (TOCE), or percutaneous ethanol(More)
