Addressing the Functional Determinants of FAK during Ciliogenesis in Multiciliated Cells
(2017)We previously identified focal adhesion kinase (FAK) as an important regulator of ciliogenesis in multiciliated cells. FAK and other focal adhesion (FA) proteins associate with the basal bodies and their striated rootlets ...

Altered Phosphorylation, Biosynthesis and Degradation of the 170 kDa Isoform of Topoisomerase II in Amsacrine-Resistant Human Leukemia Cells
(1993)Resistance to amsacrine in HL-60/AMSA is 50-100 fold compared to the parental HL-60/S cells. Synthesis and phosphorylation of topoisomerase II (TOPO II) were 2-3 fold lower in HL-60/AMSA compared to HL-60/S cells metabolically ...

Betulinic acid reduces ultraviolet-C-induced DNA breakage in congenital melanocytic naeval cells: Evidence for a potential role as a chemopreventive agent
(2001)Melanoma transformation progresses in a multistep fashion from precursor lesions such as congenital naevi. Exposure to ultraviolet (UV) light promotes this process. Betulinic acid (BA) was identified by our group as a ...

Black cohosh (Cimicifuga racemosa L.) protects against menadione-induced DNA damage through scavenging of reactive oxygen species: Bioassay-directed isolation and characterization of active principles
(2002)The roots/rhizomes of Cimicifuga racemosa L. (Nutt.) (black cohosh) have traditionally been used to treat menopausal symptoms through an unknown mechanism of action. In an effort to determine if black cohosh had additional ...

A compendium of volatile organic compounds (VOCs) released by human cell lines
(2016)Volatile organic compounds (VOCs) offer unique insights into ongoing biochemical processes in healthy and diseased humans. Yet, their diagnostic use is hampered by the limited understanding of their biochemical or cellular ...

Ets2 is necessary in trophoblast for normal embryonic anteroposterior axis development
(2006)Although the trophoblast is necessary for the growth, viability and patterning of the mammalian embryo, understanding of its patterning role is still rudimentary. Expression of the transcription factor Ets2 is restricted ...

Evaluation of estrogenic activity of plant extracts for the potential treatment of menopausal symptoms
(2001)Eight botanical preparations that are commonly used for the treatment of menopausal symptoms were tested for estrogenic activity. Methanol extracts of red clover (Trifolium pratense L.), chasteberry (Vitex agnus-castus ...

Frequency of COL4A3/COL4A4 Mutations amongst families segregating glomerular microscopic hematuria and evidence for activation of the unfolded protein response. Focal and segmental glomerulosclerosis is a frequent development during ageing
(2014)Familial glomerular hematuria(s) comprise a genetically heterogeneous group of conditions which include Alport Syndrome (AS) and thin basement membrane nephropathy (TBMN). Here we investigated 57 Greek-Cypriot families ...

The Ink4/Arf locus is a barrier for iPS cell reprogramming
(2009)The mechanisms involved in the reprogramming of differentiated cells into induced pluripotent stem (iPS) cells by the three transcription factors Oct4 (also known as Pou5f1), Klf4 and Sox2 remain poorly understood. The ...

KIF2β, a new kinesin superfamily protein in non-neuronal cells, is associated with lysosomes and may be implicated in their centrifugal translocation
(1998)Lysosomes concentrate juxtanuclearly in the region around the microtubule-organizing center by interaction with microtubules. Different experimental and physiological conditions can induce these organelles to move to the ...

New compstatin peptides containing n-terminal extensions and non-natural amino acids exhibit potent complement inhibition and improved solubility characteristics
(2015)Compstatin peptides are complement inhibitors that bind and inhibit cleavage of complement C3. Peptide binding is enhanced by hydrophobic interactions

New Insights for Ets2 Function in Trophoblast using Lentivirus-Mediated Gene Knockdown in Trophoblast Stem Cells
(2010)Mouse trophoblast stem (TS) cells represent a unique in vitro system that provides an unlimited supply of TS cells for the study of trophoblast differentiation and TS cell self-renewal. Although the mouse transcription ...

Novel compstatin family peptides inhibit complement activation by drusen-like deposits in human retinal pigmented epithelial cell cultures
(2013)We have used a novel human retinal pigmented epithelial (RPE) cell-based model that mimics drusen biogenesis and the pathobiology of age-related macular degeneration to evaluate the efficacy of newly designed peptide ...

Novobiocin- and Phorbol-12-myristate-13-acetate-induced Differentiation of Human Leukemia Cells Associated with a Reduction in Topoisomerase II Activity
(1989)Studies were conducted to determine the possible involvement of DNA topoisomerase II (Topo II) in the induction of differentiation in two human promyelocytic HL-60 leukemia cell variants that are either susceptible or ...

Phenotypic heterogeneity in osteogenesis imperfecta: The mildly affected mother of a proband with a lethal variant has the same mutation substituting cysteine for α1-glycine 904 in a type I procollagen gene (COL1A1)
(1990)A proband with a lethal variant of osteogenesis imperfecta (OI) has been shown to have, in one allele in a gene for type I procollagen (COL1A1), a single base mutation that converted the codon for α1-glycine 904 to a codon ...

Regulation of retinoid X receptor-γ gene transcript levels in rat heart cells
(1998)Retinoid X receptor-γ (RXRγ) is a transcription factor that mediates retinoid signalling and is expressed in rat heart during adult life. However, its expression in embryonic and neonatal heart has not been investigated ...

Rotenoids mediate potent cancer chemopreventive activity through transcriptional regulation of ornithine decarboxylasetissue plasminogen activator-mediated thrombolysis
(1995)For the discovery of new cancer chemopreventive agents, we have studied the potential of plant extracts to inhibit phorbol ester-induced ornithine decarboxylase (ODC) activity in cell culture. Four active rotenoids were ...
