The antibiotic AT2433-B1 belongs to a therapeutically important class of antitumor agents. This natural product contains an indolocarbazole aglycone connected to a unique disaccharide consisting of a methoxyglucose and an amino sugar subunit, 2,4-dideoxy-4-methylamino-L-xylose. The configuration of the amino sugar distinguishes AT2433-B1 from its diastereoisomer iso-AT2433-B1. Here we have inve...
MicroRNAs (miRNAs or miRs) can function as tumor-suppressor or oncogenic genes. Upregulation of miRNA-141 has been frequently observed in colorectal cancer (CRC) samples. The experimentally observed targets of miR-141 include the tumor-suppressor gene mitogen-activated protein kinase kinase 4 (MAP2K4). The aim of the present study was to investigate the role of miR-141 in the proliferation of c...
microRNAs (miRNAs) are small non-coding RNAs and have been implicated in the pathology of various diseases, including cancer. Here we report that the miRNA profiles have been changed after knockdown of one of the most important oncogene c-MYC or re-expression of a candidate tumor suppressor gene SPLUNC1 in nasopharyngeal carcinoma (NPC) cells. Both c-MYC knockdown and SPLUNC1 re-expression can ...
In this study, a bioinformatics analysis and luciferase reporter assay revealed that microRNA-141 could silence the expression of lncRNA-HOTAIR by binding to specific sites on lncRNA-HOTAIR. We used superparamagnetic iron oxide nanoparticles (SPIONs) to mediate the high expression of microRNA-141 (SPIONs@miR-141) in human amniotic epithelial stem cells (HuAESCs), which was followed by the induc...
Polymer micelles are promising drug delivery vehicles for the delivery of anticancer agents to tumors. Often, anticancer drugs display potent cytotoxic effects towards cancer cells but are too hydrophobic to be administered in the clinic as a free drug. To address this problem, a polymer micelle was designed using a triblock copolymer (ITP-101) that enables hydrophobic drugs to be encapsulated....
BACKGROUND The age limit for some adult asthma clinical trials has recently been lowered to 12 years. In this study we have made minor modifications to the standardised version of the adult Asthma Quality of Life Questionnaire (AQLQ(S)) to make it valid for patients 12 years and older (AQLQ12+). METHODS We have used two clinical trial databases, in which the AQLQ12+ was used, to compare the m...
BACKGROUND In prostate cancer (PCa), abnormal expression of several microRNAs (miRNAs) has been previously reported. Increasing evidence shows that aberrant epigenetic regulation of miRNAs is a contributing factor to their altered expression in cancer. In this study, we investigate whether expression of miR-200c and miR-141 in PCa is related to the DNA methylation status of their promoter. ME...
The in vitro and in vivo antibacterial activities of MT-141 were compared with those of cefoxitin, cefmetazole, moxalactam, cefotaxime, and cefoperazone. The MICs of MT-141 for 90% of bacterial isolates were lower than the reference drugs against clinical isolates of Campylobacter jejuni, Clostridium difficile, and Bacteroides fragilis, whereas against clinical isolates of other gram-positive, ...
Objectives: To determine the frequency of different feeding practices among infants presenting with acute diarrhea.
 Material and Methods: This cross sectional study was carried out from October 2019 to March 2020 in Paediatrics Out-Patient Department Khyber Teaching Hospital, Peshawar. Infants diarrhea were included after meeting inclusion exclusion criteria. Sampling done by consecutive ...
For differential diagnosis between hypercalcemia-induced bone metastasis and humoral hypercalcemia of malignancy (HHM), serum parathyroid hormone-related protein (PTHrP) concentrations were measured in normal subjects and patients with malignancy-associated hypercalcemia according to the presence or absence of bone metastasis, using a new sensitive PTHrP(109-141) radioimmunoassay system. The se...
