Xeroderma pigmentosum-variant (XP-V) patients have sun sensitivity and increased skin cancer risk. Their cells have normal nucleotide excision repair, but have defects in the POLH gene encoding an error-prone polymerase, DNA polymerase eta (pol eta). To survey the molecular basis of XP-V worldwide, we measured pol eta protein in skin fibroblasts from(More)
Type VII collagen is a major component of the anchoring fibrils of the dermal-epidermal adhesion on the dermal side at the lamina densa/papillary dermis interface. Dystrophic epidermolysis bullosa (DEB) emerged as a candidate for type VII collagen mutations becausing anchoring fibrils were shown to be morphologically altered, reduced in number, or(More)
BACKGROUND High cost, poor compliance, and systemic toxicity have limited the use of pentavalent antimony compounds (SbV), the treatment of choice for cutaneous leishmaniasis (CL). Paromomycin (PR) has been developed as an alternative to SbV, but existing data are conflicting. METHODOLOGY/PRINCIPAL FINDINGS We searched PubMed, Scopus, and Cochrane Central(More)
We investigated the molecular bases of spondyloepiphyseal dysplasia (SED) associated with the R992C (p.R1192C) substitution in collagen II. At the protein level, we analyzed the structure and integrity of mutant molecules, and at the cellular level, we specifically studied the effects of the presence of the R992C collagen II on the biological processes(More)
Angiogenesis, defined as new vessel growth from a pre-existing vessel, has been shown to be crucial for tumor survival and growth in several lineage-unrelated malignancies including melanoma. The concept of vasculogenic mimicry, a highly patterned microcirculation independent of angiogenesis, has also been described in melanoma. The prognostic value of(More)
The effects of citrus flavonoids on P-glycoprotein (P-gp)-mediated drug efflux were examined in human intestinal Caco-2 cells. The cellular accumulation of rhodamine-123 was measured using 10 citrus flavonoids for preliminary screening. Among the flavonoids tested, diosmin significantly increased the accumulation of rhodamine-123 in Caco-2 cells. In the(More)
Cutaneous squamous cell carcinoma (SCC) with osteoclast-like giant cells (hereafter, osteoclastic cells) is very rare; eight cases have been reported since 2006. Whether the osteoclastic cells represents a reactive or neoplastic change remains a matter of debate. Osteoclastic cells are often observed in the sarcomatous component of cutaneous carcinosarcoma.(More)
Behçet's disease (BD) is a chronic, relapsing, multisystem disorder, characterized by recurrent oral ulcer, genital ulcers, eye lesion, and skin lesion. The underlying pathology is nonspecific vasculitis of all vessel sizes, and severe vasculitis can result in fistula formation of neighboring tissues due to a necrotic process. Herein, eleven cases of BD(More)
Ipriflavone was reported to be primarily metabolized via hepatic cytochrome P450 (CYP) 1A1/2 and 2C11 in male Sprague-Dawley rats. The protein expression and/or mRNA levels of hepatic CYP1A subfamily and 2C11 was reported to be increased and decreased, respectively, in diabetic rats induced by streptozotocin (DMIS rats). Thus, the pharmacokinetic parameters(More)
