Radium-223 dichloride (radium-223) is an important therapeutic option for the treatment of patients with castration-resistant prostate cancer, symptomatic bone metastases, and no visceral disease. The unique mechanism of action of this first-in-class alpha-emitting radiopharmaceutical underlies its favorable safety profile and low incidence of myelosuppression. In the pivotal phase 3 ALpharadin...
Many microRNAs (miRNAs) are evolutionarily conserved and have intriguing expression patterns. Tissue and/or time-specific expressions of some miRNAs are presumably controlled by unique cis-acting regulatory elements that coevolved with the miRNA sequences. Exploiting bioinformatics, we identified several miRNAs whose primary transcripts could be regulated by conserved genomic elements proximal ...
Our understanding of common human diseases and how best to treat them is hampered by the complexity of the human system in which they are manifested. Unlike simple Mendelian disorders, in which highly expressive, highly penetrant mutations make it possible to identify the causal genes within families in which traits associated with the disorders segregate, common human diseases originate from a...
Background—Macrophage activation plays a crucial role in regulating adipose tissue inflammation and is a major contributor to the pathogenesis of obesity-associated cardiovascular diseases. On various types of stimuli, macrophages respond with either classic (M1) or alternative (M2) activation. M1and M2-mediated signaling pathways and corresponding cytokine production profiles are not completel...
MicroRNAs (miRNA) are a novel class of small noncoding single-stranded RNA molecules that regulate gene expression. There is increasing evidence of their importance in polycystic ovary syndrome (PCOS). The objective was to determine if miRNA-93 and miRNA-223 are differentially expressed in the circulation of women with PCOS compared to age matched women. A case-control study comparing women wit...
mTOR is a serine/threonine kinase that regulates cell growth, metabolism, proliferation, and survival. mTOR complex-1 (mTORC1) and mTOR complex-2 (mTORC2) are critical mediators of the PI3K-AKT pathway, which is frequently mutated in many cancers, leading to hyperactivation of mTOR signaling. Although rapamycin analogues, allosteric inhibitors that target only the mTORC1 complex, have shown som...
Underage drinking is a major problem at American colleges, but little is known about the extent of alcohol use in different student groups, in different colleges, and in states with different control policies. We used data from the 2001 and 3 previous Harvard School of Public Health College Alcohol Studies that compared responses of underage students with those of their 21–23-year-old peers. Un...
Multiple sclerosis (MS) is the most common autoimmune inflammatory demyelinating disease that affects the brain and spinal cord. Dysregulation or mutation of miRNA genes have been linked to the pathogenesis of MS. The miRNAs are short, 20-22 nucleotide long, single-stranded regulatory and non-protein coding RNAs that modulate the expression of multiple target genes. Among miRNAs, miR-223 has be...
Recent studies have demonstrated that exosomal microRNAs (miRNAs) are novel biomarkers and therapeutic targets for various diseases including vascular disease. However, specific exosomal miRNAs expression in stroke patients has not been reported yet. Here, we explored whether circulating exosomal miRNAs can serve as potential biomarkers for the diagnosis of acute ischemic stroke and discussed t...
BACKGROUND Increasing evidence showed that miRNAs serve as modulators of human cancer, either as oncogene or tumor suppressors. Cisplatin resistance is the most common cause of chemotherapy failure in gastric cancer (GC). However, the roles of miRNAs in cisplatin resistance of GC remain largely unknown. The aim of the study was to identify a novel miRNA/gene pathway that regulates the sensitivi...
