 Bile acids (BAs) are bioactive molecules that have potential therapeutic interest and their derived salts are used in several pharmaceutical systems. BAs have been associated with tumorigenesis of several tissues including the mammary tissue. Therefore, it is crucial to characterize their effects on cancer cells. The objective of this work was to analyse the molecular and cellular effects of the bile salts sodium cholate and sodium deoxycholate on epithelial breast cancer cell lines. Bile salts (BSs) effects over breast cancer cells viability and proliferation were assessed by MTS and BrdU assays, respectively.  https://www.selleckchem.com/products/turi.html  Activation of cell signaling mediators was determined by immunobloting. Microscopy was used to analyze cell migration, and cellular and nuclear morphology. Interference of membrane fluidity was studied by generalized polarization and fluorescence anisotropy. BSs preparations were characterized by transmission electron microscopy and dynamic light scattering. Sodium cholate and sodium deoxycholate had dual effects on cell viability, increasing it at the lower concentrations assessed and decreasing it at the highest ones. The increase of cell viability was associated with the promotion of AKT phosphorylation and cyclin D1 expression. High concentrations of bile salts induced apoptosis as well as sustained activation of p38 and AKT. In addition, they affected cell membrane fluidity but not significant effects on cell migration were observed. In conclusion, bile salts have concentration-dependent effects on breast cancer cells, promoting cell proliferation at physiological levels and being cytotoxic at supraphysiological ones.  https://www.selleckchem.com/products/turi.html  Their effects were associated with the activation of kinases involved in cell signalling.Plant viruses are the most significant factors associated with massive economical losses in agricultural industries worldwide. Accordingly, many studies are dedicated to making virus-resistant crop varieties each year due to the ever-changing nature of viruses. Recently genome engineering methods have been used to confer interference against eukaryotic viruses. Research results on genome editing technics, in particular, CRISPR-Cas9, promises a feasible solution to make virus-resistant crops. In this research, we explored the possibility of utilizing CRISPR-Cas9 to obtain TYLCV resistant tomato varieties. Moreover, to overcome any potential off-target effects of Cas9, we used an inducible promoter to initiate Cas9 activity in case of the virus attack. Cas9 vector was transformed by the rgsCaM promoter, known as an endogenous silencer of RNAi and overexpressed after a virus attack. The golden gate cloning method was applied to construct sgRNAs. Intergenic region and coat protein-coding sequences of TYLCV were used to design sgRNAs. Infiltrated sensitive Money Maker varieties analyzed by real-time PCR, showed a significant reduction or delayed accumulation of viral DNA compared to the control plants. This result demonstrates the efficiency of using an inducible promoter in CRISPR-Cas9 constructs.The increasing worldwide incidence of mycobacteriosis and the need to achieve improved clinical management makes nontuberculous mycobacteria (NTM) genotyping a useful tool. However, because of technical difficulties, medium size microbiology laboratories do not attempt to compare the genetic patterns that each of their isolates present. We have aimed to optimize a genotyping method with a reduced hands-on experimental time and that requires few technical resources. A strategy based on the Amplified Fragment Length Polymorphism (AFLP) methodology was developed using two rare-cutters enzymes (SacI and BglII). One out of seven primers was sequentially used in each amplification reaction that was analyzed by agarose gel electrophoresis. This approach makes it possible the timely genotyping of a moderate number of strains and its characterization without the need of image analysis software. We have genotyped 28 Mycobacterium intracellulare and 4 M. abscessus. Clinical researchers are encouraged to routinely genotype their NTM isolates.Superoxide dismutase is one of the key antioxidant enzymes accountable for the eradication of free radicals generated during various metabolic processes. This is first study reporting a thermostable MnSOD obtained from a xerophytic plant, Nerium oleander. The full-length gene identified using Rapid amplification of cDNA ends revealed an open reading frame of 699 bp flanked by 5'UTR and 3'UTR of 134 bp and 198 bp respectively. The corresponding NeMnSOD protein was cloned and expressed in Escherichia coli. The purified protein yields a band of 25.4 kDa, which established a specific activity of 2617 units mg-1 of protein and under native condition yield bands of 52 kDa and 110 kDa, confirming the dimeric and tetrameric state of the protein. The Km and Vmax of 0.078 ± 0.008 mM and 1052.3 ± 33.59 units mg-1 of protein, respectively. The purified enzyme demonstrated thermostability by retaining more than 20% activity at a temperature 70 ℃. The enzyme functioned at pH range of 4-9.0 with maximum activity at pH 7.4. Sodium azide, effectively inhibited the activity of enzyme confirming it to be MnSOD. The enzyme activity was least affected on treatment with strong denaturants (Urea, guanidine HCl and SDS) and harsh chemicals (DTT, CHAPS and β-mercapto-ethanol) These experimental data validated with Insilco analysis revealed that NeMnSOD possessed thermo as well as kinetically stable moiety which can be further exploited with its applications in the field of pharmaceutical, food and cosmetic industry, which urge for such thermostable enzyme.BACKGROUND Deficiency of 17β-hydroxysteroid dehydrogenase type 3 (17β-HSD3) is a rare autosomal recessive 46,XY disorder of sex development (DSD). It is due to pathogenetic variants in the HSD17B3 gene. Mutated genes encode an abnormal enzyme with absent or reduced ability to convert Δ4-androstenedione (Δ4-A) to testosterone (T) in the fetal testis. Affected individuals are usually raised as females and diagnosis is made at puberty, when they show virilization. METHODS A girl with a presumptive diagnosis of complete androgen insensitivity syndrome underwent endocrine and genetic assessment. Long-term follow-up was reported. RESULTS The diagnosis of 17β-HSD3 deficiency was made (stimulated T/Δ4-A ratio 0.15; HSD17B3 gene analysis c.277+4A>T in intron 3/c.640_645del (p.Glu214_Glu215del) in exon 9. After extensive information, parents decided to maintain female sex. Gonadal removal was performed and histological evaluation demonstrated deep fibrosis of testicular tissue. Follow-up till 8.5 years of age showed somatic and neuro-psychological development fitting with the female sex.
