Ubiquitin-conjugating enzymes (E2 enzymes) such as UBE2T target proteins for degradation via the proteasome. Here, we examined the effects of UBE2T on the progression of gastric cancer. UBE2T was highly expressed in gastric tumors and gastric cancer cells. siRNA-mediated suppression of UBE2T inhibited gastric cancer cell proliferation and colony formation by promoting cell cycle arrest at G2/M phase and increasing apoptosis. Suppression of UBE2T also attenuated the invasive and metastatic abilities of gastric cancer cells by altering expression of epithelial-mesenchymal transition (EMT)-related factors...

PURPOSE: Brahma (BRM) is a critical catalytic subunit of the SWI/SNF chromatin remodeling complex; expression of BRM is commonly lost in various cancer types. BRM promoter polymorphisms (BRM-741; BRM-1321) are associated with loss of BRM expression, and with cancer risk/survival. We evaluated these two polymorphisms in the overall survival (OS) of esophageal adenocarcinoma (EAC) patients. RESULTS: Of 270 patients, 37% were stage IV. Minor allele frequencies were 47-49%; 15% were double-homozygotes...

Long non-coding RNAs (lncRNAs) serve critical roles in cancer development and progression. Herein, through next generation RNA sequencing and experimental validations, we determined the expression status of RP11-708H21.4 in colorectal cancer (CRC) and explored its clinical significance and biological functions in CRC. Differentially expressed lncRNAs from CRC samples and corresponding normal mucosa tissues was screened through RNA sequencing, and RP11-708H21.4 was selected for further experimental validation...

Anti-microtubule drugs, such as paclitaxel (PTX), are extensively used for the treatment of numerous cancers. However, growing evidence has shown that PTX resistance, either intrinsic or acquired, frequently occurs in patients and results in the failure of treatment, contributing to the high cancer mortality rate. Therefore, it is necessary to identify the genes or pathways involved in anti-microtubule drug resistance for future successful treatment of cancers. Pygopus2 (Pygo2), which contains a Zn-coordinated plant homeodomain (PHD) finger domain, is critical for β-catenin-dependent transcriptional switches in normal and malignant tissues and is over-expressed in various cancers, including human brain glioma...

Two critical questions one must answer as one applies the results of a clinical trial to clinical practice are: (1) Regardless of whether the trial result is likely to be replicated or reproduced in a second large-scale trial, are the results likely to be reproduced in one's practice? (2) Regardless of whether the experimental treatment was better than the alternative on average for a population of patients, are the results clinically important for a given patient in one's practice? To determine if a study result is likely to be reproduced in one's clinical practice, it may be helpful to answer 5 questions: (1) Have steps been taken to minimize bias? (2) Is the result likely due to the treatment? (3) Is the result unlikely due to chance? (4) Is the study population representative of one's patients? (5) Is the totality of evidence consistent? If the answer to all 5 questions is "yes," then we posit that the trial result is likely to be reproduced in one's practice...

BACKGROUND: Cystic fibrosis (CF) is the most common autosomal-recessive disorder in western countries. Previous studies have demonstrated an important role of sphingolipids in the pathophysiology of cystic fibrosis. It has been shown that ceramide has a central role in various pulmonary infections, including those with Pseudomonas aeruginosa (P. aeruginosa). Ceramide is accumulated in the airways of CF mice and patients. However, little is known about a potential role of glucosylceramide in cystic fibrosis...

Network models of healthcare systems can be used to examine how providers collaborate, communicate, refer patients to each other, and to map how patients traverse the network of providers. Most healthcare service network models have been constructed from patient claims data, using billing claims to link a patient with a specific provider in time. The data sets can be quite large (106-108 individual claims per year), making standard methods for network construction computationally challenging and thus requiring the use of alternate construction algorithms...

The cytoplasmic peptide:N-glycanase (Ngly1 in mammals) is a de-N-glycosylating enzyme that is highly conserved among eukaryotes. It was recently reported that subjects harboring mutations in the NGLY1 gene exhibited severe systemic symptoms (NGLY1-deficiency). While the enzyme obviously has a critical role in mammals, its precise function remains unclear. In this study, we analyzed Ngly1-deficient mice and found that they are embryonic lethal in C57BL/6 background. Surprisingly, the additional deletion of the gene encoding endo-β-N-acetylglucosaminidase (Engase), which is another de-N-glycosylating enzyme but leaves a single GlcNAc at glycosylated Asn residues, resulted in the partial rescue of the lethality of the Ngly1-deficient mice...

The ability to accurately detect and analyze rare cells in a cell population is critical not only for the study of disease progression but also for next flow cytometry systems in clinical application. Here, we report the development of a prototype device, the 'Rare cell sorter', for isolating and recovering single rare cells from whole blood samples. On this device, we utilized an open-channel microfluidic chip for rare cell isolation. And the advantage of open-channel allows us to recover the isolated rare cell directly from the chip...

BACKGROUND: Access to highly specialized health care services and support to meet the patient's specific needs is critical for health outcome, especially during age-related transitions within the health care system such as with adolescents entering adult medicine. Being affected by an orphan disease complicates the situation in several important respects. Long distances to dedicated institutions and scarcity of knowledge, even among medical doctors, may present major obstacles for proper access to health care services and health chances...

Obstetrician-gynecologists often are the sole providers of health care to female patients. Because cardiovascular disease is the leading cause of death in women in the United States, obstetrician- gynecologists must be aware of the risk factors, symptoms, and signs of cardiovascular disease and arrhythmia. Furthermore, they must be prepared to identify and treat common types of arrhythmia in this population and refer patients to cardiology for specialized care. Understanding the role of pregnancy among women with arrhythmia is critically important to optimize both maternal and fetal outcomes...

Clinicians managing obstetric patients are dependent on valid hemodynamic measurements to guide care. Heart rate and noninvasive blood pressure guide most current care. New hemodynamic monitors are being used to report research findings and are being investigated by clinicians for their value to supplement standard monitoring. These include arterial pulse contour analysis, Doppler velocimetry, and bioimpedance among others. This chapter serves to present these new devices with a critical review of their advantages and limitations, and most importantly the validity of their measurements...

Although we previously reported that the self-renewal of leukemia-initiating cells of B-lineage acute lymphoblastic leukemia (B-ALL LICs) was regulated by β-Arrestin1, a multiple-function protein, the cellular senescence is critical for LICs fate and leukemia progress, and worthy for further investigation. Here we found that depletion of β-Arrestin1 extended the population doubling time and the percentage of senile cells, the signatures of cellular senescence, of B-ALL LICs. Moreover, lack of β-Arrestin1 enhanced the expression of proteins (CBX, HIRA) and genes (P53, P16) related to senescence in leukemic Reh cells and B-ALL-LICs-derived leukemic mice...

Growing patients with congenital missing second premolars should be accurately evaluated in order to establish an appropriate treatment plan. The decision whether to close or maintain spaces in dental arches caused by missing teeth should be based on the consideration of biomechanical factors and the aesthetic traits of individual patients. Accordingly, the choice of closing spaces requires an adequate consideration of biomechanical principles in order to avoid detrimental effects on the occlusion and profile...

The heterogeneity of Rheumatoid Arthritis (RA) and the absence of clinical tests accurate enough to identify the early stages of this disease have hampered its management. Therefore, proteomics research is increasingly focused on the discovery of novel biological markers, which would not only be able make an early diagnosis, but also to gain insight into the different pathological mechanisms underlying the heterogeneity of RA and also to stratify patients, which is critical to enabling effective treatments...

AIM: To critically examine the conceptual, methodological and validity issues with the 'caring cultures' construct. BACKGROUND: Post the Francis Report, 'caring cultures' and alternative terminology such as 'culture/s of care/caring/compassionate care' have gained prominence in literature, especially within a UK policy context. However, in order to understand the value these 'caring cultures' hold in terms of clinical practice, the concept itself first needs to be understood...

Neurofibromatosis type 1 (NF1, OMIM 162200), caused by NF1 gene mutations, exhibits multi-system abnormalities including skeletal deformities in humans. Osteocytes play critical roles in controlling bone modeling and remodeling. However, the role of neurofibromin, the protein product of the NF1 gene, in osteocytes is largely unknown. This study investigated the role of neurofibromin in osteocytes by disrupting Nf1 under the Dmp1-promoter. The conditional knockout (Nf1 cKO) mice displayed serum profile of a metabolic bone disorder with an osteomalacia-like bone phenotype...
