OBJECTIVE Uterine leiomyomas are the most common tumor of the uterus. But the molecular causes of uterine leiomyoma remain unclear. We conducted the current investigation in order to elucidate the molecular mechanisms in the development of uterine leiomyoma. METHODS We employed a new and accurate reverse transcription-polymerase chain reaction (RT-PCR) method that involved annealing control p...

PURPOSE The aim of this study is to evaluate the efficacy and the safety of additional 4-week chemotherapy with capecitabine during the resting periods after a 6-week neoadjuvant chemoradiotherapy (NCRT) in patients with locally advanced rectal cancer. METHODS Radiotherapy was delivered to the whole pelvis at a total dose of 50.4 Gy for 6 weeks. Oral capecitabine was administered at a dose of...

OBJECTIVES To investigate the crucial role of miR-26a in breast cancer and to validate whether miR-26a could regulate proliferation of breast cancer cells by targeting high mobility group AT-hook 1 (HMGA1). METHODS Reverse transcription-polymerase chain reaction (RT-PCR) was used to quantify the expression levels of miR-26a in breast cancer and adjacent non-cancerous breast tissues. MTT, cell...

Unrestricted somatic stem cells (USSCs) have been recently identified in human umbilical cord blood and have been shown to differentiate into lineages representing all 3 germ layers. To characterize microRNAs that may regulate osteogenic differentiation of USSCs, we carried out expression analysis for 157 microRNAs using quantitative RT-PCR before and after osteogenic induction (t = 0.5, 24, 72...

Atherosclerosis, the major pathology of cardiovascular disease, is caused by multiple factors involving psychological stress. Corticotropin-releasing hormone (CRH), which is released by neurosecretory cells in the hypothalamus, peripheral nerve terminals and epithelial cells, regulates various stress-related responses. Our current study aimed to verify the role of CRH in macrophage foam cell fo...

PURPOSE Fibroblast growth factor (FGF) signals play fundamental roles in development and tumorigenesis. Thyroid cancer is an example of a tumor with nonoverlapping genetic mutations that up-regulate mitogen-activated protein kinase. We reported recently that FGF receptor 2 (FGFR2) is down-regulated through extensive DNA promoter methylation in thyroid cancer. Reexpression of the FGFR2-IIIb isof...

Scrub typhus, caused by infection with Orientia tsutsugamushi, is one of the most common rickettsial diseases in the Asia-Pacific region. The disease can cause up to 35% mortality if left untreated. In order to get a better understanding of the host responses to O. tsutsugamushi infection, freshly isolated peripheral blood mononuclear cells (PBMC) were infected with O. tsutsugamushi. The infect...

Drought is a major constraint to crop production, and microRNAs (miRNAs) play an important role in plant drought tolerance. Analysis of miRNAs and other classes of small RNAs (sRNAs) in barley grown under water and drought conditions reveals that drought selectively regulates expression of miRNAs and other classes of sRNAs. Low-expressed miRNAs and all repeat-associated siRNAs (rasiRNAs) tended...

AIMS To investigate candidate genes in peripheral blood mononuclear cell (PBMC) that are associated with early onset severe preeclampsia (ES-PE) and to describe candidate genes function using microarrays and real-time polymerase chain reaction (PCR). METHODS PBMC RNA was extracted from six patients with ES-PE and five uncomplicated pregnancies. The HG_U133 plus 2.0 Affymetrix GeneChips that r...
