The folding of both wild-type and mutant forms of the cystic-fibrosis transmembrane-conductance regulator (CFTR), a plasma-membrane chloride-ion channel, is inefficient. Most nascent CFTR is retained in the endoplasmic reticulum and degraded by the ubiquitin proteasome pathway. Aberrant folding and defective trafficking of CFTRDeltaF508 is the principal(More)
The viral E2 gene product plays a crucial role in the human papillomavirus (HPV) vegetative cycle by regulating both transcription and replication of the viral genome. E2 is a transcriptional repressor of the E6 and E7 viral oncogenes for HPV types 16 and 18, which are involved in cervical cancers. Using new polyclonal antibodies against the HPV16 E2(More)
Thyroid hormone (T3) is a critical regulator of intestinal epithelial development and homeostasis, but its mechanism of action within the gut is not well understood. We have examined the molecular mechanisms underlying the T3 activation of the enterocyte differentiation marker intestinal alkaline phosphatase (IAP) gene. RT-PCR and Western blotting showed(More)
OBJECTIVE The purpose of the present study was to estimate the prevalence of high-risk human papillomavirus infection and the viral load in different age groups, to describe the distribution of human papillomavirus prevalence in women enrolled in two hospitals. STUDY DESIGN We retrospectively investigated 17,148 cases undergoing hybrid capture II between(More)
Maternal vitamin D deficiency has been suggested to influence fetal and neonatal health. Little is known about vitamin D status in Chinese pregnant women. The purpose of this study was to assess the vitamin D status of pregnant women residing in Beijing in winter and evaluate the impact of maternal factors on serum 25-hydroxyvitamin D [25(OH)D] levels. The(More)
It was previously reported that Cbl-b associates with Crk-L in Jurkat T cells. However, the physiological significance of such association remains unclear. Here we examined a regulatory role of Cbl-b in Crk-L-C3G signaling pathway. We found that Cbl-b associates with, and induces, ubiquitin conjugation to Crk-L, which requires a functional RING finger.(More)
MicroRNAs (miRNAs) are important regulators of many physiological and pathological processes, including cell proliferation, apoptosis, and cell cycle arrest. In this study, we aimed to investigate the biological role of miR-155 in cervical cancer and the underlying molecular mechanism involved in tumorigenesis. The expression of miR-155 in human cervical(More)
OBJECTIVE To evaluate the prevalence of vitamin D deficiency in pregnant women and their newborns in Beijing, China and the influence of vitamin D deficiency on birth size. DESIGN A cross-sectional study. SETTING Data were collected from pregnant women who delivered during April to May 2010 at 306 Hospital of PLA in Beijing, China. SUBJECTS(More)
The engineering of T lymphocytes to express chimeric antigen receptors (CARs) aims to establish T cell-mediated tumor immunity rapidly. In this study, we conducted a pilot clinical trial of autologous or donor- derived T cells genetically modified to express a CAR targeting the B-cell antigen CD19 harboring 4-1BB and the CD3ζ moiety. All enrolled patients(More)
