What is the suggested therapy for Mycobacterium avium infection?

The activity of TLC G-65 (a liposomal gentamicin preparation), alone and in combination with rifapentine, clarithromycin, clofazimine and ethambutol, was evaluated in the beige mouse (C57BL/6J--bgj/bgj) model of disseminated Mycobacterium avium infection. TLC G-65 in combination with rifapentine appears to be an attractive regimen for the treatment of infections caused by bacteria in the M. avium complex. Rifampin 10 mg/kg daily, ciprofloxacin 500 mg twice daily, clofazimine 100 mg every day, and ethambutol 15 mg/kg orally daily for 24 weeks, with or without amikacin 10 mg/kg intravenously or intramuscularly 5 days weekly for the first 4 weeks. In vivo phage treatment may also be used in some cases.

What is the genetic basis of tuberous sclerosis?

The genetic basis of tuberous sclerosis has been attributed to mutations in one of two unlinked genes, TSC1 and TSC2. The functions of the TSC1 and TSC2 gene products, hamartin and tuberin, respectively, have remained ill defined until recently. Genetic, biochemical, and biologic analyses have highlighted their role as negative regulators of the mTOR signaling pathway. Tuberin, serving as a substrate of AKT and AMPK, mediates mTOR activity by coordinating inputs from growth factors and energy availability in the control of cell growth, proliferation, and survival. Emerging evidence also suggests that the TSC 1/2 complex may play a role in modulating the activity of beta-catenin and TGFbeta. These findings provide novel functional links between the TSC genes and other tumor suppressors.

What is the molecular function of the Chd1 protein?

The ATP-dependent chromatin-remodelling enzyme Chd1 is a 168-kDa protein consisting of a double chromodomain, Snf2-related ATPase domain, and a C-terminal DNA-binding domain. One of the two chromodomains of Chd1 specifically interacts with the methylated lysine 4 mark on histone H3 that is associated with transcriptional activity. Human CHD1 is an ATP-dependent chromatin remodeling protein, as a factor that directly and selectively recognizes histone H3 methylated on lysine 4.

Which are the most widely used computational methods for the identification of CRMs (cis-regulatory modules)?

Computational methods attempting to identify instances of cis-regulatory modules (CRMs) in the genome face a challenging problem of searching for potentially interacting transcription factor binding sites while knowledge of the specific interactions involved remains limited. When discriminating CRMs from non-coding regions, those methods considering evolutionary conservation have a stronger predictive power than methods designed to be run on a single genome. Furthermore, most methods appear to be sensitive to the composition and structure of the genome to which they are applied. CisMiner allows to perform a blind search of CRMs without any prior information about target CRMs nor limitation in the number of motifs.

Has vitamin D has been shown to reduce incidence of falls in older people in clinical trials?

The rate of falls and the number of fallers was significantly reduced in two studies evaluating the effect of medication on preventing falls; one study (85 participants) compared vitamin D versus placebo in institutionalised women after stroke with low vitamin D levels, and the other study (79 participants) evaluated alendronate versus alphacalcidol in hospitalised people after stroke. Two studies testing vitamin D versus placebo and alendronate versus alphacalcidol found a significant reduction in falls and the number of people falling. Overall, vitamin D did not reduce rate of falls (RaR 1.00, 95% CI 0.90 to 1.11; seven trials; 9324 participants) or risk of falling (RR 0.96, 95% CI 0.89 to 1.03; 13 trials; 26,747 participants), but may do so in people with lower vitamin D levels before treatment. We found 26 eligible trials of moderate quality that enrolled 45,782 participants, the majority of which were elderly and female. Vitamin D use was associated with statistically significant reduction in the risk of falls (odds ratio for suffering at least one fall, 0.86; 95% confidence interval, 0.77-0.96)

What is enCHIP?

Engineered DNA-binding molecule-mediated chromatin immunoprecipitation (enChIP) is a novel method for purification of specific genomic regions retaining molecular interactions. EnChIP using the CRISPR system efficiently isolates specific genomic regions. In this form of enChIP, specific genomic regions are immunoprecipitated with antibody against a tag(s), which is fused to a catalytically inactive form of Cas9 (dCas9), which is co-expressed with a guide RNA (gRNA) and recognizes endogenous DNA sequence in the genomic regions of interest. enChIP-mass spectrometry (enChIP-MS) targeting endogenous loci identified associated proteins. enChIP using the CRISPR system would be a convenient and useful tool for dissecting chromatin structure of genomic regions of interest.

Which protein is the E3-ubiquitin ligase that targets the tumor suppressor p53 for proteasomal degradation?

The p53 tumour suppressor protein is tightly controlled by the E3 ubiquitin ligase, mouse double minute 2 (MDM2). The RING domain E3 ubiquitin ligase Mdm2 is the master regulator of the tumor suppressor p53. It targets p53 for proteasomal degradation, restraining the potent activity of p53 and enabling cell survival and proliferation. p53 is inactivated in many human malignancies through missense mutations or overexpression of the human homologue of Mdm2 (Hdm2), an E3 ubiquitin ligase that ubiquitinates p53, thereby promoting its proteasomal degradation.

Can DNA intercalators function as topoisomerase inhibitors?

The DNA unwinding suggests DNA intercalation, which could explain the inhibition of topoisomerase II. Among its many properties, amiloride is a DNA intercalator and topoisomerase II inhibitor. Amsacrine, a DNA intercalator and topoisomerase II inhibitor, is efficacious as an antileukemogenic agent. AQ4N (1,4-bis[[2-(dimethylamino)ethyl] amino]-5,8-dihydroxyanthracene-9, 10-dione bis-N-oxide dihydrochloride) is a prodrug which is selectively activated within hypoxic tissues to AQ4, a topoisomerase II inhibitor and DNA intercalator. Amonafide is a DNA intercalator and topoisomerase II inhibitor in clinical development for the treatment of neoplastic diseases.

What is the role of invadopodia in EMT?

In a process of epithelial-mesenchymal transition (EMT), besides changing their adhesive repertoire, cancer cells employ developmental processes to gain migratory and invasive properties that involve a dramatic reorganization of the actin cytoskeleton and the concomitant formation of membrane protrusions required for invasive growth. An important type of such membrane protrusions are the invadopodia, which have been increasingly recognized as important drivers of local invasion in metastasis. They are basally-localized, actin-rich structures that concentrate protease activity to areas of the cell in contact with the extracellular matrix.

What are cancer driver genes?

Recent sequencing and resequencing (i.e., polymorphism identification) efforts have catalyzed the quest for 'driver' mutations (i.e., those genetic alterations which contribute to the transformation of a normal cell to a proliferating cancerous cell) in distinction to 'passenger' mutations which reflect mutations that merely build up in course of normal and unchecked (i.e., cancerous) somatic cell replication and proliferation. Analysis of the frequency of specific mutations across different tumors has been able to identify some, but not all of the mutated genes that contribute to tumor initiation and progression. A subset of these mutations contribute to tumor progression (known as "driver" mutations) whereas the majority of these mutations are effectively neutral (known as "passenger" mutations).

What is the effect of ivabradine in heart failure with preserved ejection fraction?

I(f)-channel inhibition potentially exhibits beneficial effects in diastolic heart failure. In patients with heart failure with preserved ejection fraction (HFpEF), short-term treatment with ivabradine increased exercise capacity, with a contribution from improved left ventricular filling pressure response to exercise as reflected by the ratio of peak early diastolic mitral flow velocity to peak early diastolic mitral annular velocity. Ivabradine has demonstrated benefits in HFpEF without improving mortality. In db/db, a model of HFpEF, ivabradine improved vascular stiffness, left ventricular contractility, and diastolic function. Furthermore, ivabradine reduces cardiac fibrosis in hypercholesterolemic rabbits.

Describe the usefulness of the SPIKE database in human signaling pathways

The rapid accumulation of knowledge on biological signaling pathways and their regulatory mechanisms has highlighted the need for specific repositories that can store, organize and allow retrieval of pathway information in a way that will be useful for the research community. SPIKE (Signaling Pathways Integrated Knowledge Engine; http://www.cs.tau.ac.il/&~spike/) is a database for achieving this goal, containing highly curated interactions for particular human pathways, along with literature-referenced information on the nature of each interaction. To make database population and pathway comprehension straightforward, a simple yet informative data model is used, and pathways are laid out as maps that reflect the curator’s understanding and make the utilization of the pathways easy. The database currently focuses primarily on pathways describing DNA damage response, cell cycle, programmed cell death and hearing related pathways. Pathways are regularly updated, and additional pathways are gradually added. The complete database and the individual maps are freely exportable in several formats. The database is accompanied by a stand-alone software tool for analysis and dynamic visualization of pathways.

What is the Barr body?

The Barr body is the inactive X chromosome in a female somatic cell. It is readily identified as plano-convex structure of 2-3 micron in diameter on the periphery of the nuclear membrane. One of the X-chromosomes by a random inactivation process condenses to form X-chromatin (Barr body) in early embryonic life. Once this occurs, it is final and fixed for that cell and all its descendants (1,2). Barr body is an inactivated X chromosome in the normal female somatic cell. Inactivation of these chromosomes is known as Lyonization. Lyonization has both genetic and clinical significance. Barr body can be easily identified with ordinary stains. It also helps in identifying the sex of an individual when used judiciously. The Barr body has long been recognized as the cytological manifestation of the inactive X chromosome (Xi) in interphase nuclei. Despite being known for over 50 years, relatively few components of the Barr body have been identified.

What is the biological role of expansins in fungi?

Expansins are extracellular proteins that increase plant cell-wall extensibility. These wall-loosening proteins are involved in cell wall extension and polysaccharide degradation. In fungi expansins and expansin-like proteins have been found to localize in the conidial cell wall and are probably involved in cell wall remodeling during germination.

What is the mode of action of Hsp90 inhibitors?

Pharmacologic inhibition of Hsp90 involves interaction with the ATP-binding site of the chaperone. This exerts antiproliferative effects resulting in a marked suppression of tumor growth. Following treatment with a Hsp90 inhibitor, expression of a number of proteins is affected, and most notably the Hsp90 clients, leading to dysregulation of intracellular signal transduction, immune response, cell growth and maintenance, transport, and metabolism, finally resulting in cancer cell death through activation of both intrinsic and extrinsic apoptotic pathways.

What distinguishes lantibiotics from antibiotics?

Lantibiotic compounds are ribosomally synthesized antimicrobial peptides against which bacteria are not able to produce resistance, hence making them a good alternative to antibiotics. It is interesting that low levels of resistance have been reported for lantibiotics compared with commercial antibiotics. Given that there are very few examples of naturally occurring lantibiotic resistance, attempts have been made to deliberately induce resistance phenotypes in order to investigate this phenomenon. Other general forms of resistance include the formation of spores or biofilms, which are a common mechanistic response to many classes of antimicrobials.

is intense physical activity associated with longevity ?

Several survival studies showed that professional athletes has higher longevity than general population. These epidemiological data matches the evidences that long-term endurance training induces in elderly subjects an increased HRV and a higher exercise working capacity, which are well-established predictors of cardiovascular and overall mortality, and also telomere length.

Can a given genotype exhibit opposite fitness effects (beneficial and detrimental) within the same environment?

A given genotype can be either beneficial or detrimental, even deleterious, depending on the environment in which an organism lives. This is known as antagonistic pleiotropy. Antagonistic pleiotropy can operate even within the same environment. For example, in Escherichia coli, certain mutations can exhibit beneficial, deleterious or neutral fitness effects at different growth rates. Also, antagonistic pleiotropy is involved in the evolution of ageing, since a certain genotype may affect late- and early-life fitness in opposite directions.
