mTOR pathway activation in focal cortical dysplasia.

Background: Focal cortical dysplasia (FCD) is a localized cortical malformation and considerable morphological overlap exists between FCD IIB and neurological lesions associated with Tuberous sclerosis complex (TSC). Abnormal mTOR pathway secondary to somatic mTOR mutation and TSC gene mutation linked to PI3K/AKT/mTOR pathway have supported the hypothesis of common pathogenesis involved. Role of converging pathway, viz.

Loss of /INI1 Immunoexpression in Chordoid Meningiomas.

Background: Chordoid meningiomas have an aggressive clinical course characterized by frequent recurrences. Recent whole-genome sequencing studies demonstrated Chr22 loss in chordoid meningiomas not accounted for by NF2 mutations. SMARCB1/INI1 is a candidate gene on Chr22, which has not been analyzed extensively in meningiomas.

C11orf95-RELA fusions and upregulated NF-KB signalling characterise a subset of aggressive supratentorial ependymomas that express L1CAM and nestin.

Ependymomas (EPN) show site specific genetic alterations and a recent DNA methylation profiling study identified nine molecular subgroups. C11orf95-RELA and YAP1 fusions characterise the RELA and YAP1 molecular subgroups, respectively, of supratentorial (ST)-EPNs. Current guidelines recommend molecular subgrouping over histological grade for accurate prognostication.

Study of β-catenin and BRAF alterations in adamantinomatous and papillary craniopharyngiomas: mutation analysis with immunohistochemical correlation in 54 cases.

Craniopharyngiomas (CP) are rare benign epithelial tumors, with two histological variants, namely the adamantinomatous variant (ACP) and the rarer papillary variant (PCP). They are locally infiltrative and surgically challenging tumors with severe long term morbidity. CTNNB1 mutations with β-catenin immunopositivity and BRAFV600E mutations with anti-VE immunopositivity have been recently described in ACPs and PCPs respectively.

Role of mTOR signaling pathway in the pathogenesis of subependymal giant cell astrocytoma - A study of 28 cases.

Background: Subependymal giant cell astrocytomas (SEGA) are slow-growing benign intraventricular tumors, the pathogenesis of which is debated. Recent studies have shown that tuberous sclerosis complex (TSC) 1 and TSC2 genes are linked to the mammalian target of rapamycin (mTOR) cell signaling pathway. We aimed to analyze TSC1 and TSC2 gene mutation, hamartin and tuberin protein expression, and protein expression of mTOR signaling cascade in a series of SEGA to determine their role in pathogenesis.

Turritopsis nutricula (T. nutricula) is the one of the known reported organisms that can revert its life cycle to the polyp stage even after becoming sexually mature, defining itself as the only immortal organism in the animal kingdom. Therefore, the animal is having prime importance in basic biological, aging, and biomedical researches.

Electrostatic mis-interactions cause overexpression toxicity of proteins in E. coli.

A majority of E. coli proteins when overexpressed inhibit its growth, but the reasons behind overexpression toxicity of proteins remain unknown. Understanding the mechanism of overexpression toxicity is important from evolutionary, biotechnological and possibly clinical perspectives.

Identifying a predictive model for response to atypical antipsychotic monotherapy treatment in south Indian schizophrenia patients.

Atypical antipsychotic (AAP) drugs are the preferred choice of treatment for schizophrenia patients. Patients who do not show favorable response to AAP monotherapy are subjected to random prolonged therapeutic treatment with AAP multitherapy, typical antipsychotics or a combination of both. Therefore, prior identification of patients' response to drugs can be an important step in providing efficacious and safe therapeutic treatment.

Diverse facets of COMT: from a plausible predictive marker to a potential drug target for schizophrenia.

Dopaminergic system in the prefrontal cortex (PFC) is known to regulate the cognitive functions. Catechol-O-methyl transferase (COMT), one of the major modulators of prefrontal dopamine function, has emerged as an important determinant of schizophrenia associated cognitive dysfunction and response to antipsychotics. A common Val->Met polymorphism (rs4680) in the COMT gene, associated with increased prefrontal dopamine catabolism, impairs prefrontal cognition and might increase risk for schizophrenia.

In vitro and in vivo evaluation of linear polyethylenimine nanoparticles.

bPEI (polyethylenimine, 25 kDa, gold standard) is highly effective in transfection efficiency owing to its high buffering capacity, however, cytotoxicity limits its use in in vivo applications. We hypothesized that partial conversion of secondary amines in IPEI to tertiary amines, while preserving the overall number of amines, would result in improved buffering capacity, which may, in turn, improve transfection efficiency of the resulting nanoparticles with cell viability comparable to that of native IPEI. IPEI was crosslinked with BDE to obtain a series of IPEI nanoparticles (LPN-1 to LPN-8) which were obtained in approximately 80-85% yield.

Gene expression profiling and network analysis reveals lipid and steroid metabolism to be the most favored by TNFalpha in HepG2 cells.

Background: The proinflammatory cytokine, TNFalpha, is a crucial mediator of the pathogenesis of several diseases, more so in cases involving the liver wherein it is critical in maintaining liver homeostasis since it is a major determiner of hepatocyte life and death. Gene expression profiling serves as an appropriate strategy to unravel the underlying signatures to envisage such varied responses and considering this, gene transcription profiling was examined in control and TNFalpha treated HepG2 cells.

Methods And Findings: Microarray experiments between control and TNFalpha treated HepG2 cells indicated that TNFalpha could significantly alter the expression profiling of 140 genes; among those up-regulated, several GO (Gene Ontology) terms related to lipid and fat metabolism were significantly (p<0.

Mutated glutathione S-transferase in combination with reduced glutathione shows a synergistic effect in ameliorating oxidative stress and airway inflammation.

Oxidative stress is implicated in the pathogenesis of asthma, and antioxidant levels are reduced in asthma patients. Previously, glutathione S-transferase (GST) with reduced IgE binding suppressed oxidative stress and modulated airway inflammation to some extent in mice. GST catalyzes the quenching of reactive oxygen species by reduced glutathione (GSH) and the absence of any one of them may limit antioxidative behavior.

SCA-LSVD: a repeat-oriented locus-specific variation database for genotype to phenotype correlations in spinocerebellar ataxias.

Repeat expansion has been implicated in 10 out of 17 candidate genes identified for autosomal dominant cerebellar ataxias (ADCAs)-commonly referred as spinocerebellar ataxias (SCAs). Though genetically distinct, the SCAs share a large number of features that confound their clinical classification. In addition, there is a difference in the prevalence and phenotypic expression of ataxias between different ethnic groups.

Genetic susceptibility to schizophrenia: role of dopaminergic pathway gene polymorphisms.

Aim: We investigated 16 polymorphisms from three genes, dopamine receptor D2 (DRD2), catechol-O-methyl transferase (COMT) and brain derived neurotrophic factor (BDNF), which are involved in the dopaminergic pathways, and have been reported to be associated with susceptibility to schizophrenia and response to antipsychotic therapy.

Materials & Methods: Single-locus association analyses of these polymorphisms were carried out in 254 patients with schizophrenia and 225 controls, all of southern Indian origin. Additionally, multifactor-dimensionality reduction analysis was performed in 422 samples (243 cases and 179 controls) to examine the gene-gene interactions and to identify combinations of multilocus genotypes associated with either high or low risk for the disease.
