Abstract Eukaryotic microorganisms are constantly challenged by reactive oxygen species derived endogenously or encountered in their environment. Such adversity is particularly applied to Saccharomyces cerevisiae under harsh industrial conditions. One of the major oxidants to challenge S. cerevisiae is linoleic acid hydroperoxide (LoaOOH). This study, which used genome-wide microarray analysis ...

Human extraskeletal myxoid chondrosarcomas (EMCs) are soft tissue tumors characterized by specific chromosomal abnormalities. Recently, a proportion of EMCs were found to harbor a characteristic translocation, t(3;9)(q11-12;q22), involving the TFG (TRK-fused gene) at 3q11-12 and the TEC (Translocated in Extraskeletal Chondrosarcoma) gene at 9q22. The present study used both in ...

The mitotic spindle is assembled by the coordinated action of centrosomes and kinetochore microtubules. An evolutionally conserved protein family, transforming acidic coiled-coil (TACC), has been shown to be involved in this process. In humans, TACC3 is aberrantly expressed in a variety of human cancers, but its biological significance remains to ...

Bone marrow mesenchymal stem/stromal cells (BM-MSCs) can infiltrate into tumors and subsequently evolve into tumor resident MSCs in tumor microenvironment. In this study, using a mouse lymphoma model, we showed that the lymphoma resident MSCs (L-MSCs) are able to confer tumor-promoting property to the naïve cocultured BM-MSCs. Examination of cytokines ...

The constitutive activation of β-catenin signaling in the mammary basal epithelial cell layer in transgenic K5ΔNβcat mice leads to basal-type tumor development. Integrins of the β1 family and integrin-mediated signaling events have an important role in breast tumor growth and progression. We show here that the deletion of α3β1 integrin, ...

The ability to degrade extracellular matrix is critical for tumor cells to invade and metastasize. Recent studies show that tumor cells use specialized actin-based membrane protrusions termed invadopodia to perform matrix degradation. Invadopodia provide an elegant way for tumor cells to precisely couple focal matrix degradation with directional movement. Here ...

Tuberous sclerosis complex 1 (TSC1) and TSC2 are suppressors of mechanistic target of rapamycin (mTOR). mTOR is the major component of two protein complexes: mTOR complex 1 (mTORC1) and mTORC2. Inactive mutation of either TSC1 or TSC2 unleashes mTOR signaling and consequently causes TSC, a benign tumor syndrome affecting multiple ...

Polycyclic aromatic hydrocarbons (PAHs) are of considerable concern due to their well-recognised toxicity and especially due to the carcinogenic hazard which they present. PAHs are semi-volatile and therefore partition between vapour and condensed phases in the atmosphere and both the vapour and particulate forms undergo chemical reactions. This article briefly ...

Introduction Although several theories of delusions have been put forward, most do not offer a comprehensive diagnosis-independent explanation of delusion aetiology. This study used a non-clinical sample to provide empirical support for a novel transdiagnostic model of delusions that implicates aberrant semantic memory and emotion perception processes as key factors ...

Commonly consumed fruits showed remarkable variation in antimutagenicity when assayed by E. coli rifampicin resistance assay, and Java Plum (Syzygium cumini) was found to be one of the most potent fruits. Its anthocyanins contributed maximally to the observed antimutagenicity and resolved into three distinct bands in HPTLC. Although these bands ...

It has been suggested that the favorable side-effect profiles of atypical antipsychotics (e.g. clozapine and amisulpride) are related to their ���100-fold faster dissociation from dopamine D2 receptors (D2R) compared with typical antipsychotics (e.g. haloperidol and chlorpromazine). Fast dissociation would entail rapidly reversible antagonism; however, this has not been thoroughly studied ...
