Project description:HeLa cells were cultured in DMEM, supplemented with 10% (v/v) FCS and penicillin/streptomycin under 5% CO2 at 37°C. For iCLIP, HeLa cells expressing eIF4A3-GFP or PTB-GFP were induced with doxycycline to adjust the level of recombinant protein to the level of the endogenous counterpart and irradiated with 150 mJ/cm2 UV light (254 nm). The iCLIP cDNA libraries for eIF4A3 and PTB were sequenced with 50 bp on an Illumina HiSeq instrument.

Project description:First experiment: Cells were cultured in sulfur amino acid-free DMEM supplemented with 0.1 mM methionine + 0.1 mM cysteine (complete) or supplemented only with 0.1 mM methionine (cysteine-free). Cells were cultured in either medium for 42 h (Long + Cys; Long -Cys) or in cysteine-free medium for 36 h followed by 6 h in complete medium (Short +Cys) Second experiment: C3A/HepG2 cells were cultured in sulfur amino acid-free DMEM supplemented with 0.1 mM Met and 0.1 mM Cys (complete) or supplemented only with 0.1 mM Met (cysteine-devoid). Cells were cultured in complete medium for 42 h (Long +Cys) or in complete medium for 36 h followed by cysteine-devoid medium for 6 h (Short -Cys). Keywords: amino acid deprivation

Project description:Purpose: To understand the molecular mechanisms underlying Cd exposure-induced diseases. Methods: Immortalized human bronchial epithelial cells (BEAS-2B) were cultured in Dulbecco’s Modified Eagle’s Medium (DMEM, Cellgro) supplemented with 1% Penicillin Streptomycin and 10% Fetal Bovine Serum (FBS, Atlanta Biologicals) at 37 degree C and 5 % CO2. For Cd exposure, 0, 2.5, 5 and 10 µM of CdCl2 was added to the media and the cells were cultured for 72h. Results: This study shows that cadmium exposure induces SNAIL1 expression via miR-30e downregulation and the cells undergo epithelial-mesenchymal transition.

Project description:Interest in exploiting algae as a biofuel source and the role of nutrient deficiency in inducing triacylglyceride (TAG) accumulation in cells necessitates a strategy to efficiently formulate species-specific culture media that can be easily manipulated. Using the reference organism Chlamydomonas reinhardtii, we tested the hypothesis that modeling trace element supplements on the ionomes of cells would result in optimized cell growth. We characterized the ionomes of multiple wild-type Chlamydomonas strains in various culture conditions and developed a revised trace element solution to parallel our measurements. Comparison of cells growing in the revised supplement versus a traditional trace element solution revealed faster growth rates and higher maximum cell densities with the revised recipe. RNA-seq analysis of cultures growing in the traditional versus revised medium suggest that the variation in transcriptomes was smaller than that found between laboratories using the same supplement. Visual observation did not reveal defects in cell motility or mating efficiency. Ni2+-inducible expression from the CYC6 promoter remained a useful tool, albeit with an increased amount of Ni2+ supplementation due to the introduction of an EDTA buffer system in the revised medium. Equilibrium modeling of the revised supplement predicts less metal precipitation in the revised medium. Other advantages include more facile preparation of trace element stock solutions that can readily be adapted for deficiency studies, a reduction in total chemical use, a more consistent batch-to-batch formulation, and long-term stability (up to 5 years). Under the new growth regime, we analyzed cells growing under different macro- and micronutrient-deficiencies. In N and S deficiency, cells accumulate TAG as well in the new medium as previously demonstrated. Fe and Zn deficiency also induced TAG accumulation as suggested by Nile Red and Bodipy staining. This ionomic approach can be used to efficiently optimize culturing conditions for other algal species to improve growth and assay cell physiology. Sampling of Chlamydomonas CC-1021 (2137) cultivated in TAP medium supplemented with a revised trace element recipe based on ionomic data.

Project description:Cortical 1.4C18 and medullary 3.10 TEC lines (mTEC) were cultured in 10% fetal bovine serum-supplemented RPMI 1640 medium at 37 ?C in a 5% CO2 atmosphere. Confluent cultures of 3.10 mTEC cell line were cultured during 72 h in RPMI medium as above mentioned and total RNA was extracted using the mirVana kitM-. (Ambion, Austin, TX, USA).

Project description:SmallRNAs are proposed as key regulators in many cellular processes including angiogenesis, suggested candidates for future therapeutic applications. But, regulation and modulation of smallRNAs in pathology conditions and normal conditions are poorly recognized, supremely in wound care management. Current study focused to identify the smallRNA regulatory network in simulated microgravity sensitized Human Umbilical Cord Vein Endothelial cells (HUVECs) and gravity (1g) as a background. HUVECs were purchased from Lonza (Cat.No) and cultured in EGM2 medium (Cat.No CC3162) supplemented with 10% Fetal Bovine, 1% penicillin-streptomycin (W/V). Cells were cultured in RPM (Randomized positioned machine) for 2 hours at 37°C.

Project description:The bacterium Corynebacterium glutamicum can produce ʟ-glutamic acid under certain growth conditions. ʟ-glutamic acid is used as a flavor enhancer, food supplement, or primary chemical raw material. It, therefore, plays an essential economic role with an annual production of over 2½ million tons. Due to metabolic development, the product range of C. glutamicum has been expanded to include all biogenic amino acids, vitamins, and more. Previously published metabolic models of C. glutamicum have been supplemented with new metabolic data and expanded with data from new systems biology programs to result in this consensus model.

Project description:The goal of this study was to evaluate the transcriptional response of 4 human duodenal enteroid lines on monolayers to norovirus infections (GII.4). Enteroids were plated as monolayers in Intesticult (Stem Cell Technologies) proliferation medium. After 1 day of cell growth as a monolayer, the proliferation medium was changed with differentiation medium for 5 days. Five-day-differentiated monolayers were washed and were either mock-infected or inoculated with human norovirus supplemented with 500 μM glycochenodeoxycholic acid (GCDCA), for 1 to 2 h at 37°C. Total RNA was extracted using the Qiagen RNeasy kit and paired-end Illumina sequencing was performed.
