MetabolomicsGlobal metabolomics of fireflies (Coleoptera: Lampyridae) explore metabolic adaptation to fresh water in insects

Aquatic insects are well-adapted to freshwater environments, but metabolic mechanisms of such adaptations, particularly to primary environmental factors (e.g., hypoxia, water pressure, dark light and abundant microbes), are poorly known. Most firefly species (Coleoptera: Lampyridae) are terrestri...

MetabolomicsAromatic amino acids metabolism shapes autophagy mediated adaptation to iron deprivation in glioma

GBM displays profound iron dependence and metabolic plasticity, yet how iron deprivation interfaces with stress-response pathways and amino acid metabolism in glioma remains incompletely understood. DFO, an iron chelator and hypoxia mimetic, is widely used experimentally, but the integration of a...

MetabolomicsLysine acetyltransferase Rv0998 coordinates transcriptional and metabolic adaptation of Mycobacterium tuberculosis to acidic pH

Mycobacterium tuberculosis (Mtb) survives host defences by adapting to host conditions, including acid stress, during infection. A critical survival strategy involves pH homeostasis, mediated by complex signalling systems that regulate metabolic reprogramming and stress responses. While ...

MetabolomicsMulti-omics Analysis Reveals New Insights into Yak Lung Fibrosis Mechanisms Under High-Altitude Adaptation

The lung of yak is an important adaptive organ in the cold and low oxygen environment. Hypoxia can induce the pathological manifestations of pulmonary fibrosis in yak, but there was no study on hypoxia induced pulmonary fibrosis in yak. In this study full target metabolomics were used to conduct ...

TranscriptomicsMultiple oxygen tension environments reveal diverse patterns of transcriptional regulation in primary astrocytes
The central nervous system normally functions at O2 levels which would be regarded as hypoxic by most other tissues. However, most in vitro studies of neurons and astrocytes are conducted under hyperoxic conditions without consideration of O2-dependent cellular adaptation. We analyzed the reactivi...

TranscriptomicsTime resolved ribosome profiling study of oxygen and glucose deprivation of rat pheochromocytoma cells
Oxygen and glucose metabolism plays a pivotal role in many (patho)physiological conditions. In particular, oxygen and glucose deprivation (OGD) occurs during ischemia and stroke, resulting in extensive tissue injury and cell death. We applied time-resolved ribosome profiling technique to assess earl...

ProteomicsAdaptation of Burkholderia cenocepacia to low oxygen drives changes consistent with adaptation to chronic infection.
Cystic fibrosis (CF) is characterised by chronic respiratory infections, involving opportunistic pathogens, including Burkholderia cenocepacia. The CF lung comprises hypoxic niches that drives bacterial adaptation and the adaptability of pathogens to this environment is key to their successful colon...

TranscriptomicsMycobacterium tuberculosis Lsr2 is a global transcriptional regulator required for adaptation to changing oxygen levels and virulence
To survive a dynamic host environment, Mycobacterium tuberculosis must endure a series of challenges from reactive oxygen and nitrogen stress, to drastic shifts in oxygen availability. The mycobacterial Lsr2 protein has been implicated in reactive oxygen defense via direct protection of DNA. To exam...

TranscriptomicsNext Generation Sequencing identifies O2-responsive genes in the human pathogenic fungus Aspergillus fumigatus
Low oxygen conditions are not only common to natural environments but also occur during tissue invasive growth in the human host. Only few cellular factors have been identified up to now that allow the fungus to efficiently adapt its energy metabolism to the lack of O2. In the present study, we cult...

TranscriptomicsHypoxia, ketoconazole, and the UPC2 gene in Candida albicans
This SuperSeries is composed of the following subset Series: GSE24073: Transcriptional profile of Candida albicans during Hypoxic conditions. GSE24074: Transcriptional profile of Candida albicans DAY286 culture without ketoconazole versus DAY286 culture with 0.04 μg/ml ketoconazole, both at 20% oxy...
