Connexins play vital roles in hearing, including promoting cochlear development and sustaining auditory function in the mature cochlea. Mutations in connexins expressed in the cochlear epithelium, Cx26 and Cx30, cause sensorineural deafness and in the case of Cx26, is one of the most common caus...

Connexin 31 (Cx31) is considered a suppressor for many tumors. Ginsenoside (Rg1) is a traditional Chinese herb that is widely acknowledged due to its anti-tumor characteristics. However, limited studies have focused on the role of Rg1 in papillary thyroid cancer (PTC) cells. In the current study...

Chondromodulin-I (ChM-I) is an angiogenesis inhibitor isolated from fetal bovine cartilage. Here, we report the nucleotide sequence of chicken ChM-I cDNA. Chicken mature ChM-I had a significantly larger N-terminal hydrophilic domain than its mammalian counterparts. Chicken embryos expressed mult...

Chondromodulin-I expression in the growth plate of young uremic rats.

The insertion site of the tendon to the skeletal element is hypovascular and is one of the most common sites of dysfunction in the musculoskeletal system. However, the resident cells have been poorly defined due to a lack of a specific marker for tenocytes. We previously reported that Tenomoduli...

In tissues and/or organs of mesenchymal origin, the vasculature is usually well developed. However, there are certain hypovascular tissues that exhibit powerful anti-angiogenic resistance, implying the presence of tissue-type specific inhibitors of angiogenesis. Hyaline cartilage is one example,...

Pleiotrophin and chondromodulin-I are low molecular weight proteins that are abundant (20 μg/g tissue) in fetal cartilage and difficult to detect in adult cartilage. We characterized their gene and protein expression patterns to gain a better understanding of their roles in the regulation of li...

Chondromodulin-I (Chm-I) is a glycoprotein that stimulates the growth of chondrocytes and inhibits angiogenesis in vitro. Mice lacking the Chm1 gene show abnormal bone metabolism and pathological angiogenesis in cardiac valves in the mature stage although they develop normally without aberration...

To identify novel proteins that might help clarify the molecular mechanisms underlying chondromodulin-I (ChM-I) induction of mesenchymal stem cells (MSCs) differentiate into chondrocytes. MSCs are triggered to differentiate into chondrocytes, which are recognized as important factors in cartilag...

We investigated the expression of the Chondromodulin-I (ChM-I) gene, a putative tumor suppressor gene in cartilaginous tumors, by quantitative RT-PCR in 15 chondrosarcomas (CSs). Eight CSs expressed the ChM-I gene at the level higher than those in articular cartilage (positive cases), whereas th...

We recently identified chondromodulin-I as a crucial antiangiogenic factor for maintaining cardiac valvular function. Normally, avascular cardiac valves from ApoE−/− mice and humans with valvular heart disease showed angiogenesis and increased expression of vascular endothelial cell growth facto...

SummaryObjectivesHypoxia is known to stabilize hypoxia-inducible factor (HIF) and initiate angiogenic signaling cascade. However, cartilage living in hypoxia environment can maintain avascularity. It is well known that abrogation of avascularity is related to cartilage degradation in osteoarthri...

Phenazines are important nitrogen-containing secondary metabolites that display a range of biological functionalities. However, these compounds have shown lethal effects on humans and, the fate of phenazine in the ecosystem remains uncertain. In this study, we investigated that Sphingobium yanoi...

Phenazine-1-carboxylic acid (PCA) is a natural product that has been proven effective against a number of soil-borne fungal phytopathogens and registered for biofungicide against rice sheath blight in China. In order to improve the phloem mobility of phenazine-1-carboxylic acid (PCA), four PCA d...

Xanthomonas oryzae pv. oryzae (Xoo) causes bacterial leaf blight (BLB) and can be effectively controlled by phenazine-1-carboxylic acid (PCA), an antibiotic secreted by Pseudomonas spp. PCA resistance in Xoo was investigated in this research. Only four PCA-resistant strains were obtained by exte...

A new rhizosphere soil bacterium that exhibits antimicrobial potential against human pathogens was isolated. On the basis of 16S ribosomal RNA nucleotide sequence homology and subsequent phylogenetic tree analysis, the strain PUW5 was identified as Pseudomonas putida. A bioactive metabolite was ...

Microbial fuel cells (MFCs) are a renewable green energy source that uses microorganisms to catalytically convert chemical energy into electrical energy. The efficiency of extracellular electron transfer (EET) from the microbe cell to the anode electrode plays a key role in the MFC. However, the...

Phenazine-1-carboxylic acid has extensive pharmacological activity, including antibiotic and immunomodulatory, but the anticancer activity remains unknown. Treatment of prostate cancer cell line (DU145) with phenazine-1-carboxylic acid stimulated inhibition of cell proliferation in concentration...

Natural phenazines in secondary metabolites of bacteria have been receiving increasing attention in recent years due to their potential usage as antibiotics. In the present study, a rapid and reliable capillary zone electrophoresis (CZE) method was developed and validated for monitoring for the ...

The oomycete pathogen, Phytophthora meadii, causes various diseases in Hevea brasiliensis at different stages of its life cycle. The study reports the structural characterization of the active principle from the culture filtrate of Alcaligenes sp. EIL-2 (GenBank ID: HQ641257) offering antagonist...
