Hypoxia and lactate influence VOC production in A549 lung cancer cells.

Project description:Introduction: Cancer cells emit characteristic volatile organic compounds (VOCs), which are potentially generated from ROS-based lipid peroxidation of polyunsaturated fatty acids. The metabolism of such VOCs and their regulation remain to be fully investigated. In fact, the enzymes involved in the synthesis of these VOCs have not been described yet. Methods: In this study, we firstly conducted in vitro enzyme assays and demonstrated that recombinant alcohol dehydrogenase (ADH) converted Trans 2-hexenal into Trans 2-hexenol. The latter has previously been reported as a cancer VOC. To study VOC metabolism, 14 different culture conditions were compared in view of Trans 2-hexenol production. Results and discussion: The data indicate that hypoxia and the addition of lactate positively influenced Trans 2-hexenol production in A549 cancer cells. The RNAseq data suggested certain gene expressions in the VOC pathway and in lactate signaling, parallel to VOC production. This implies that hypoxia and lactate signaling with a VOC production can be characteristic for cancer in vitro.

Lactate- and hypoxia-induced beta-glucan masking in responding and non-responding Candida albicans clinical isolates

Project description:RNA sequencing was performed on Candida albicans clinical isolates that display normal (isolates: 3560, 3605, 3609, 4108, 4259) or aberrant (isolates: 3534, 3544, 3621, 3636, 4036) beta-glucan masking in response to lactate and hypoxia. Each clinical isolate was grown to exponential phase in GYNB under normoxic conditions and then exposed for 5 h to: (a) 1% lactate; (b) 0% lactate control; (c) hypoxia; or (d) normoxic control. Three independent experiments were performed for each clinical isolate.

Gene expression in HTR-8/SVneo cells exposed to hypoxia or treated with sodium L-lactate

Project description:Chronical hypoxia is a common occurrence following reduced uteroplacental blood flow resulting from incomplete trophoblast invasion and abnormal vascular remodeling of the spiral arteries in PE. Hypoxia can lead to active glycolysis, which increases the production of lactate, a substrate for histone lactylation. To screen for genes that may be regulated by histone lactylation in PE placentas, we performed RNA-seq in HTR-8/SVneo cells under hypoxia or treated with sodium L-lactate. The results showed that 3578 genes were upregulated in the HTR-8/SVneo cells under hypoxia compared to those under normoxia, and 355 genes were upregulated in HTR-8/SVneo cells treated with sodium L-lactate compared to the control cells. 152 upregulated genes in the HTR-8/SVneo cells under hypoxia and those treated with sodium L-lactate overlapping.

RNA-seq profiling of parental and NLUCAT1-deleted A549 cells under hypoxia

Project description:Parental or NLUCAT1 CRISPR/Cas9-deleted A549 clones (WT A549 Hx, n = 1 clone; DEL A549 Hx, n = 1 clone) were exposed to hypoxia (Hx) at 1% O2 for 24 hours. Libraries were generated from 500 ng of total RNAs using TruSeq Stranded Total RNA kit with Ribo-Zero (Illumina) and sequenced on a NextSeq500 sequencer (Illumina) with 2x75bp paired-end chemistry. Reads were aligned to the human genome release hg19 using STAR v2.4.0a with default parameters.
