Intermediate filaments (IF) belong to major cytoskeletal components of metazoan cells. We have previously determined a tissue specific expression and assembly properties of all eleven cytoplasmic IFs (IFA-1 - IFA-4, IFB-1, IFB-2, IFC-1, IFC-2, IFD-1, IFD-2, IFP-1) in C. elegans and reported an essential function for four (IFA-1, IFA-2, IFA-3 and IFB-1) of them. In this study we continued the characterisation of the IF proteins in C. elegans by searching for in vivo polymerisation partners of the IFA proteins...

BACKGROUND: Phosphoribosylaminoimidazole carboxylase (PAICS), a de novo purine metabolic enzyme, has been identified as an oncogene in several tumor types, including breast cancer and prostate cancer. However, the role of PAICS in human lung adenocarcinoma (LADC) requires further study. METHODS: In this research, the effects of PAICS on the occurrence and prognosis of LADC were evaluated using integrative bioinformatics analyses. RESULTS: By employing the bioinformatics analyses of several public databases, PAICS, which is overexpressed in the LADC tissues, was identified as a potential tumor-promoting gene in LADC biology...

Mitochondrial genome organization of sea anemones appears conserved among species and families, and is represented by a single circular DNA molecule of 17 to 21 kb. The mitochondrial gene content corresponds to the same 13 protein components of the oxidative phosphorylation (OxPhos) system as in vertebrates. Hallmarks, however, include a highly reduced tRNA gene repertoire and the presence of autocatalytic group I introns. Here we demonstrate that the mitochondrial genome of the deep-water sea anemone Protanthea simplex deviates significantly from that of other known sea anemones...

TPA is considered to be a tumor promoting molecule that induces the expression of COX-2 protein. However, it is contradictory to find that TPA can induce tumor cell apoptosis and exert antitumor activity. Therefore, the role of TPA in tumorigenesis and development has not yet been elucidated. Here we show that TPA can promote the apoptosis of breast cancer cells and increase the ratio of Bax/Bcl-2. It is suggested that TPA may induce apoptosis of breast cancer cells through mitochondrial apoptosis pathway. Further studies showed that TPA could cause mitochondrial dysfunction and trigger mitochondrial apoptotic pathway...

Members of the sucrose non-fermenting-1-related protein kinase 2 (SnRK2) family play central roles in the abscisic acid (ABA) signaling pathway and in mediating osmotic stress signaling and tolerance in plants. Previously, 12 full-length coding sequences that belong to SnRK2 gene family were identified and cloned in wild apple species Malus prunifolia. In this study, one of the members, MpSnRK2.10, was overexpressed in Arabidopsis and apple to investigate its potential function in response to drought stress...

In living organisms, the MicroRNAs act as an important role by controlling regulatory mechanisms, and likely manipulating the output of numerous protein-coding genes. Several computational databases, algorithms and tools have been developed to discover the miRNA target genes. But, the existing methods obtain poorer results in identification of miRNA target gene. Hence in this research work, integrated prediction scores is used to identify the microRNA target interactions and hybrid fuzzy algorithms are used to make final predictions...

Ion uptake mechanisms are diverse in fish species, certainly linked to duplication events that have led to the presence of a multitude of paralogous genes. In fish, Na+ uptake involves several ion transporters expressed in different ionocyte subtypes. In the European sea bass Dicentrarchus labrax, several key transporters potentially involved in Na+ uptake have been investigated in seawater (SW) and following a 2 weeks freshwater (FW) acclimation. Using gel electrophoresis, we have shown that the Na+ /H+ -exchanger 3 (nhe3, slc9a3) is expressed in gills and kidney at both salinities...

Common pregnancy detection methods in dairy cattle have limits in sensitivity and timing. Thus, we aimed at finding new early pregnancy biomarkers in milk. A previous study in milk cells and skim milk suggested the possible use of several miRNAs for this purpose. In order to make the sampling procedure more convenient for daily use and to include the milk fat into analysis, here, a similar study was repeated using whole fresh milk of days 4, 12, 18 and 21 of pregnancy and non-pregnant day-matched controls, respectively...

The quest to elucidate the molecular mechanism of action of rapamycin in the early 1990s led to the discovery of the novel TOR (target of rapamycin) proteins in yeast and mammalian cells. This was a major breakthrough that resulted in the development of new rapamycin analogs as anti-cancer agents, and launched new research that revealed the pre-eminent biological role of mTOR (mammalian or mechanistic TOR). Beyond mediating rapamycin sensitivity, the TOR proteins are nutrient sensing protein kinases, conserved from yeast to man, with a core function in regulating cell growth, metabolism and overall cell survival...
