Class I histone deacetylases (HDACs) inhibit expression of tumor suppressor genes by removing acetyl groups from histone lysine residues, thereby increasing cancer cell survival and proliferation. We evaluated the expression of class I HDACs in cholangiocarcinoma (CCA). HDAC3 expression was specifically increased in CCA tissues and correlated with reduced patient survival. HDAC3 overexpression ...

The mechanism that regulates the growth of ovarian clearcell adenocarcinoma (CCA) are not well understood. We investigated the role of several growth factors that bind to membrane tyrosine kinase receptors and added them to the ovarian CCA cell lines KK, RMG-1, and HAC-II to evaluate their effect on growth and cellular invasion. Epidermal growth factor and transforming growth factor-alpha signi...

An aneurysm involved in common carotid artery (CCA) bifurcation is a rare clinical condition. There are not enough natural follow-up data, and there is no evidence-based treatment algorithm [1]. An endovascular approach is used to treat CCA bifurcation aneurysms, as it offers some advantages in selected patient populations; nonetheless, closure of the aneurysmal segment in CCA bifurcation using...

Shear stress (SS) is thought to be constant throughout the vascular system. Evidence for this supposition is scarce, however. To verify this hypothesis in vivo, we assessed common carotid (CCA) and brachial artery (BA) peak and mean wall shear rate (SR) noninvasively in 10 healthy volunteers (23.7 +/- 3.4 yr) with an ultrasound SR estimation system. SS was estimated from SR and calculated whole...

BACKGROUND The matching of vascular supply to neuronal metabolic demand during cognitive engagement is known as neurovascular coupling (NVC). Arterial stiffness is a prominent determinant of pulsatility in the systemic circulation and may thus indirectly impact NVC. In this pilot investigation, we explored changes in carotid artery stiffness and cerebrovascular hemodynamic pulsatiltiy during co...

BACKGROUND AND PURPOSE The Framingham stroke risk score (FSRS) and Framingham cardiovascular risk score (FCRS) estimate the individual absolute cardiovascular and stroke risks. Common carotid artery intima-media thickness (CCA-IMT) and carotid plaques (CPs) are markers of subclinical atherosclerosis and help in the early identification of presymptomatic individuals. The purpose of this study wa...

Crustose coralline algae (CCA) are key producers of carbonate sediment on reefs today. Despite their importance in modern reef ecosystems, the long-term relationship of CCA with reef development has not been quantitatively assessed in the fossil record. This study includes data from 128 Cenozoic coral reefs collected from the Paleobiology Database, the Paleoreefs Database, as well as the origin...

Cholangiocarcinoma (CCA) is a fatal disease with increasing worldwide incidence and is characterized by poor prognosis due to its poor response to conventional chemotherapy or radiotherapy. Long non-coding RNAs (lncRNAs) play key roles in multiple human cancers, including CCA. Cancer progression related lncRNA taurine-up-regulated gene 1 (TUG1) was reported to be involved in human carcinomas. H...

Cholangiocarcinoma (CCA) is one of the most malignant human cancers with increasing incidence worldwide. LncRNAs have emerged as gene regulators and prognostic biomarkers in a variety of neoplasms. PANDAR, a novel cancer-related lncRNA, has been reported to be upregulated in diverse human carcinomas. In this study, we aimed to investigate the clinical significance of lncRNA PANDAR in CCA and ex...

We investigated the role of actin filament associated protein 1 antisense RNA1 (AFAP1-AS1) lncRNA in promoting cholangiocarcinoma (CCA). qRT-PCR analysis of patient samples showed that AFAP1-AS1 expression was higher in CCA tumors than matched adjacent non-tumor tissue. AFAP1-AS1 levels were also higher in CCA cell lines (HuCCT1 and TFK-1) than a normal biliary epithelium cell line (HIBEpic). A...
