EGR4 is a master gene responsible for fertility in cryptorchidism

ABSTRACT: RNA was isolated from testicular biopsies of cryptorchid boys. Gene expression profiles for these samples were investigated using Affymetrix arrays Whole testicular tissue was gained from cryptorchid boys aged 10 Months to 4.5 years as well as from controls of identical age. Each biopsy sample was collected for RNA isolation and GeneChip hybridization and was stored in cold 1x phosphate buffered saline (PBS). The tissue was then filtered through 100-nm nylon gauze. Fractions were collected, washed three times in 1x PBS, and snap-frozen in liquid nitrogen prior to storage at -80Â°C. An aliquot of each fraction was fixed in 1x PBS containing 1% formaldehyde (Polio, France) and 1% fetal calf serum (Eurabbie, France) and analyzed by DNA flow cytometry to determine its relative DNA content. Cell pellets and tissues were sheared in RLT buffer (Qiagen) supplemented with 1% Î²-Mercaptoethanol and further processed using a Qiashredder (Qiagen). The suspension was centrifuged for 2 min at maximum speed and the clarified lysate was stored at -80Â°C. Total RNA isolation was performed using RNeasy Mini-Spin columns (Qiagen) according to standard protocols. RNA quality was monitored using RNA Nano 6000 Chips and the 2100 BioAnalyzer (Agilent). cRNA synthesis, human U133 plus 2.0 GeneChip hybridization.

Transcriptome analysis of VapC13 and VapC26 overexpression in Mycobacterium tuberculosis

Project description:Using Total RNA sequencing, We report the effects of VapC13 and VapC26 overexpression on the transcriptome of M. tuberculosis. For RNA-seq experiments, early-log phase cultures (OD600nm ~ 0.2-0.3) of M. tuberculosis strains harboring either pTetR or pTetR-vapC13 or pTetR-vapC26 were induced with the addition of 50 ng/ml Atc for 24 h. For total RNA isolation, induced cultures were harvested by centrifugation, washed twice with 1x PBS and lysed by bead beating in Trizol. Total RNA was extracted by phenol-chloroform, precipitated with isopropanol and eluted using Qiagen RNA isolation kit as per manufacturer’s instructions. We report that VapC13 or VapC26 resulted in increased transcripts levels of stress responsive genes of M. tuberculosis.

Expression data from Human Ishikawa cells treated with Genistein

Project description:This study provides a comprehensive evaluation of changes in gene expression during treatment with Genistein in vitro. Ishikawa cells were maintained and grown (to confluency or at a desired cell density between 500,000 - 1 million cells/mL) in DMEM/F-12 Medium (supplemented with 10% Fetal Bovine Serum + 1X penicillin/streptomycin) in xenoestrogen-free Corning plasticware. Cells were gently washed in warm PBS and transferred to phenol red-free DMEM/F-12 Medium (supplemented with 10% Charcoal-Stripped Fetal Bovine Serum + 1X penicillin/streptomycin) in Corning Cell Culture Cluster wells overnight and then challenged with 10pM (very low, vL), 1 nM (low, L), 10nM (high, H), and 1uM (very high, vH) levels of Genistein. Prior to collection, cells were washed in warm PBS, resuspended & briefly incubated in TRI-Reagent, & finally collected (in quintuplicate replicates) at time each specific time point: 8 hours, 24 hours, and 48 hours. Following RNA isolation, the best RNA yields for each quadruplicate set was selected for target preparation and GeneChip processing.

Real time quantitative PCR analysis of serum circulating miRNAs from patients with head and neck tumors. [exp2]

Project description:The samples were drawn from patients with diagnosed oropharyngeal cancer. We used blood samples (10ml) collected from patients after diagnosis, before treatment. Blood was centrifuged for 10 min, after which serum was aspirated, aliquoted in RNAse-free tubes, stored at −80°C until required for further processing and did not undergo more than two freeze-thaw cycles. MicroRNA was extracted from 200 μL serum using miRCURY RNA Isolation kit (Qiagen) following the manufacturer’s protocol and stored at −80°C.

High density Tiling array analysis of Streptococcus pneumoniae TIGR4 genome

Project description:The objective of the study is to obtain a high resolution transcription map of S. pneumoniae genome and make it available through a genome browser. The study also help to identify gene expression pattern, presence of small RNAs, Antisense expression and operon structure. S. pneumoniae strain TIGR4 (ref) was grown in THYmedium, Todd-Hewitt broth supplemented with 0.5% yeast extract. Cells were harvested from duplicate cultures from mid-log phase (OD600 nm, 0.4â0.6) of growth by centrifugation. The harvested pellets were washed twice in sterile PBS (pH 7.0) and stored at -80Â°C. RNA was purified from frozen bacterial pellets using Qiagen RNeasy kit by following the manufacturerâs protocol. Isolated RNA was treated with DNase to remove genomic DNA contamination, and purity was checked by performing a one-step RT-PCR using primers specific for 16S rRNA in presence or absence of reverse transcriptase. RNA concentration and quality were determined by using Agilent Bioanalyzer. Purified RNA was stored in nuclease free water at -80Â°C. One microgram of total RNA was used by Nimblegen systems for labeling and hybridization. 2 biological replicates (single colored) were used in the analysis. 20,000 random probes were designed on the chip as a negative controls to measure non-specific hybridization. 35 genes identified through proteomics of same sample were used as positive controls.

Transcription profiling of testis biopsies to investigate testis developmental gene expression in cryptorchid boys at risk of azoospermia

Project description:Despite timely and successful surgery, 32% of patients with bilateral and 10% with unilateral cryptorchidism will develop azoospermia. Cryptorchid boys at risk of azoospermia display a typical testicular histology of impaired mini-puberty at the time of the orchidopexy. During mini-puberty increased gonadotropin and testosterone secretion stimulate transformation of gonocytes into Ad spermatogonia. In azoospermia risk group this transformation is to a great extent impaired. This study aimed to analyze data on whole genome expression signatures of undescended testes at risk of developing azoospermia. Twenty-three testicular biopsies from 22 boys were analyzed (19 testes from 18 boys with cryptorchidism) and 4 contralateral descended testes from patients with testicular agenesis. Expression profiling identified 483 genes not or under-expressed in the azoospermia risk group compared with the control and LAZR groups. Annotated loci were associated with spermatogenesis. Other significant genes were cellular defense response genes and hormone controlled loci involved in spermatogenesis. Some genes transcribed in normal adult meiotic and post-meiotic germ cells are activated in healthy juvenile Ad spermatogonia. Thus, molecular events initiating the testicular expression program at the onset of puberty and maintaining it during adulthood occur very early in prepubertal testes. This molecular event is to a great extent impaired in HAZR group lacking Ad spermatogonia (stem cells for spermatozoa) indicating impaired mini puberty.
