Background: The myometrium is involved in many processes during pregnancy and the estrous/menstrual cycle. Peroxisome proliferator-activated receptors (PPARs) can be regulators of the processes occurring in the myometrium. In the present study, we determined the global transcriptome profile of the porcine myometrium during the peri-implantation period and the late luteal phase of the estrous cycle.

Taxonomic classification using metabarcoding is a commonly used method in microbiological studies of environmental samples and during monitoring of biotechnological processes. However, it is difficult to compare results from different laboratories, due to the variety of bioinformatics tools that have been developed and used for data analysis. This problem is compounded by different choices regarding which variable region of the gene and which database is used for taxonomic identification.

Knowledge about paternal-effect-genes (PEGs) (genes whose expression in the progeny is influenced by paternal factors present in the sperm) in fish is very limited. To explore this issue, we used milt cryopreservation as a specific challenge test for sperm cells, thus enabling selection amidst cryo-sensitivity. We created two groups of Eurasian perch (Perca fluviatilis) as a model - eggs fertilized either with fresh (Fresh group) or cryopreserved (Cryo group) milt from the same male followed by phenotypic-transcriptomic examination of consequences of cryopreservation in obtained progeny (at larval stages).

Article Synopsis
  • Tanshinones are bioactive red pigments found in Danshen, a key herb in Traditional Chinese Medicine, but their biosynthetic pathway is only partially understood.
  • Recent studies reveal significant differences in the diterpenoid profiles of different Salvia species, indicating a complex genetic relationship.
  • A combination of Liquid Chromatography-Mass Spectrometry and RNA sequencing was used to examine the leaves and roots of two Salvia species, leading to the identification of thousands of transcripts and key gene families involved in the biosynthesis of tanshinones.
