Are you the one that don't have such hobby? So, it's important for you to start having that hobby. You know, reading is not the force. We're sure that reading will lead you to join in better concept of life. Reading will be a positive ...

A fraction of cancer cells maintain telomeres through the telomerase-independent, 'Alternative Lengthening of Telomeres' (ALT) pathway. ALT relies on homologous recombination (HR) between telomeric sequences; yet, what makes ALT telomeres recombinogenic remains unclear. Here we show that the RNA endonuclease RNaseH1 regulates the levels of RNA-DNA hybrids between telomeric DNA and the long nonc...

BACKGROUND AND OBJECTIVES Clinically, hepatitis B virus (HBV) infection is observed to be associated with nephropathy. However, previous population-based studies failed to show an association between HBV infection and CKD. Therefore, this cross-sectional study was designed to further explore this association. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS A representative sample of 6854 Chines...

NK cells are innate lymphoid cells that mediate potent anti-tumor responses against B cell malignancies in conjunction with anti-CD20 mAbs. ALT-803 is a superagonist IL-15 and dimeric IL-15Ra-IgG-Fc fusion protein that effectively trans-presents IL-15 and exhibits prolonged in vivo pharmacokinetics compared to rhIL-15. We hypothesized that ALT-803 will augment anti-CD20 mAb (rituximab)-directed...

The maintenance of telomere length is essential for the indefinite proliferation of cancer cells. This is most often achieved by the activation of telomerase; however, a substantial number of cancers lack detectable telomerase activity and are classified as using an alternative lengthening of telomeres (ALT) pathway. We showed recently that ALT cells have a high level of extrachromosomal telome...

Various serum biomarkers have been developed for predicting head and neck squamous cell carcinoma (HNSCC) prognosis. However, none of them have been proven to be clinically significant. A recent study reported that the ratio of aspartate aminotransaminase (AST) to alanine aminotransaminase (ALT) had a prognostic effect on non-metastatic cancers. This study aimed to examine the effect of the AST...

OBJECTIVES Fatty liver is a common cause of liver disease in children. However, the epidemiology of pediatric fatty liver is limited to single-center case series of nonalcoholic fatty liver disease (NAFLD). Obesity and insulin resistance are major established risk factors for NAFLD. The role of gender, race, and ethnicity on the prevalence of fatty liver in obese children is unknown. METHODS ...

OBJECTIVE To estimate and compare associations of alanine aminotransferase (ALT) and gamma-glutamyltransferase (GGT) with incident diabetes. RESEARCH DESIGN AND METHODS ALT and GGT were studied as determinants of diabetes in the British Women's Heart and Health Study, a cohort of 4,286 women 60-79 years old (median follow-up 7.3 years). A systematic review and a meta-analysis of 21 prospectiv...

Alternative end joining (Alt-EJ) chromosomal break repair involves bypassing classical non-homologous end joining (c-NHEJ), and such repair causes mutations often with microhomology at the repair junction. Since the mediators of Alt-EJ are not well understood, we have sought to identify DNA damage response (DDR) factors important for this repair event. Using chromosomal break reporter assays, w...

BACKGROUND Alanine aminotransferase (ALT) is commonly used to measure liver injury in resource-limited settings. Elevations in ALT are predictive of increased mortality from liver disease and may influence the choice of first-line antiretroviral therapy (ART). METHODS A cross-sectional analysis of the prevalence and predictors of elevated ALT (defined as >40 IU/L) was conducted. ART-naïve, HI...
