Nesfatin-1 expression and blood plasma concentration in female dogs suffering from cystic endometrial hyperplasia and pyometra and its possible interaction with phoenixin-14.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundNesfatin-1 is a neuropeptide that regulates the hypothalamic-pituitary-gonadal axis and may play a role in uterus function. It is co-expressed with other peptides, such as phoenixin, which can influence sex hormone secretion. Our previous research has confirmed that phoenixin-14 is involved in the development of cystic endometrial hyperplasia (CEH) and pyometra in dogs. Therefore, based on the similarities and interactions between these neuropeptides, we hypothesized that nesfatin-1 might also regulate the reproductive system in dogs. This study aimed to determine the expression of nesfatin-1 and its interaction with phoenixin-14 in dogs with CEH or pyometra compared to healthy females, and concerning animals' body condition score (BCS 4-5/9 vs. BCS > 5/9).
resultsThe analysis of nesfatin-1 in the uterus of bitches consisted of qPCR, western blot and immunofluorescence assays, and ELISAs. The results showed significantly higher nesfatin-1 encoding gene, nucleobindin-2 mRNA (Nucb2) and nesfatin-1 protein expression in overweight females and those suffering from CEH or pyometra compared to healthy animals. The immunoreactivity of nesfatin-1 was elevated in the uteri of bitches with higher BCS > 5/9. Moreover, nesfatin-1 blood concentrations increased in all examined overweight bitches. In the case of phoenixin signals, we found opposite results, regardless of the female body condition score.
conclusionThe etiology of CEH and pyometra are not fully known, although we have expanded the level of knowledge with respect to the possible interaction of nesfatin-1 and phoenixin in female dogs' uteri. They interact oppositely. With increasing female body weight, the expression of nesfatin-1 in the uterus and its peripheral blood concentration increased. However, for female dogs affected by CEH and pyometra, a decreased level of phoenixin-14, irrespective of their body condition score is characteristic. This knowledge could be crucial in the development of biomarkers for these conditions, which may lead to earlier recognition.
