MetabolomicsZinc oxide nanoparticles supplementation improve the quality and lipid profiles of boar frozen semen

Oxidative stress frequently causes a reduction in the quality of frozen-thawed sperm. Zinc oxide nanoparticles (ZnONPs) has an antioxidant protective effect on frozen semen of animals such as goats, camels and buffaloes. However, it is not clear whether ZnONPs can improve the quality and lipid co...

MetabolomicsUntargeted metabolomics approach using UPLC-ESI-QTOF-MS to explore the metabolome of fresh-cut iceberg lettuce
An untargeted metabolomics approach using UPLC-ESI-QTOF-MS was performed to explore the metabolome of iceberg lettuce and the changes related to storage time and genetics. Two cultivars with different browning susceptibility, fast- browning (FB) and slow-browning (SB) were studied juts after cutting...

TranscriptomicsQuantitative Expression Profiling of RNA from Formalin-Fixed, Paraffin-Embedded (FFPE)and Fresh Frozen (FF) Breast Cancer samples
Unluckily, FFPE archival methods lead to partial RNA degradation, limiting the amount of derivable information. This study aims to evaluate if the DASL gene expression assay, designed to generate reproducible data from degraded RNAs, is a reliable method to apply on RNA from FFPE tissues. In order t...

TranscriptomicsTranscription profiling of fresh, frozen and RNALater preserved human uterine myometrium samples
We used quantitative RNA expression profiling on the Affymetrix U133 human expression array to validate quantitative expression results obtained with the tissue preservative RNALater against snap frozen and fresh tissues as a means of routine tissue collection and temporary storage. By using split ...

ProteomicsQuantitative proteomic analysis of fresh-frozen human breast tissue and tumor samples using microLC-SWATH-MS
Future improvements in the field of breast cancer prevention, diagnosis and treatment require deeper knowledge and better understanding of the molecular processes and signaling pathways that lead to the transformation of normal cells to cancer ones and the disease progression. Quantitative proteome ...

TranscriptomicsAn array based analysis of miRNA expression comparing matched frozen and FFPE human tissue samples
MicroRNAs (miRNAs) are small non-coding RNAs that repress gene expression at the post transcriptional level via an antisense RNA-RNA interaction. Generally, miRNAs derived from snap frozen or fresh samples are used for array based profiling. Since tissues in most pathology departments are available ...

ProteomicsComparison of matched formalin-fixed paraffin embedded and fresh frozen tissue reveals bias in proteomic profiles
Tissue biopsies are most commonly archived in a paraffin block following tissue fixation with formaldehyde (FFPE) or as fresh frozen tissue (FFT). While both methods preserve biological samples, little is known about how they affect the quantifiable proteome. We performed a ‘bottom-up’ proteomic ana...
