Background: Nesfatin-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.

Allyl isothiocyanate (AITC) is the pungent ingredient of brassica species, used as a food additive and flavoring agent, including condiments such as wasabi, horseradish, and mustard. Currently, there is much evidence that AITC modulates glucose and lipids metabolism. Interestingly, AITC has been shown to improve glycaemia, and insulin action along with the induction of a deepened decline in blood insulin levels in T2DM rats.

Furthermore, the molecular basis of mixed intra-patient tumor responses remains unclear. Here, we show that patients with metastatic lung adenocarcinoma harbouring co-mutations of EGFR and TP53, are more likely to have mixed intra-patient tumor responses to EGFR tyrosine kinase inhibition (TKI), compared to those with an EGFR mutation alone.

Therefore, we investigated the impact of neuronostatin on the proliferation and differentiation of isolated rat brown preadipocytes.
View Article and Find Full Text PDFOrexins A (OXA) and B (OXB) (hypocretin 1 and 2) are neuropeptides produced in the brain and peripheral tissues. Biological activities of orexins are mediated through activation of two G-protein coupled receptors termed as orexin 1 receptor (OX1R) and orexin 2 receptor (OX1R). Orexin system (OXA, OXB, OX1R, OX2R) was implicated in controlling sleep, energy expenditure, appetite, reproduction as well as metabolism and energy homeostasis.

Chemotherapy is a primary method to treat cancer. While chemotherapeutic drugs are designed to target rapidly dividing cancer cells, they can also affect other cell types. In the case of dermal cells and macrophages involved in wound healing, cytotoxicity often leads to the development of chronic wounds.

In vivo, chronic infusion of GIP_HUMAN [22-51] in ApoE-/- mice enhanced the development of aortic atherosclerotic lesions and upregulated inflammatory and proatherogenic proteins. In the present study, we evaluate the effects of GIP_HUMAN [22-51] on insulin mRNA expression and secretion in insulin-producing INS-1E cells and isolated rat pancreatic islets.

However, the role of SPX in fetal life, in children, and in adolescent metabolism is limited. Therefore, we decided to check whether obesity affects the concentration of SPX in the mother's peripheral blood (MB) and umbilical cord blood (UCB).

Recently, we showed that PNX-14 is downregulated in bitches with cystic endometrial hyperplasia and pyometra. The objective of this study was to determine the expression of Smim20, PNX-14, and its putative receptor GRP173 in the canine ovary (both healthy and those with ovarian cysts), periovarian adipose tissue (PAT) and in the endometrium during the oestrous cycle.

Recently, we reported that NPB promotes the adipogenesis of rat white and brown preadipocytes as well as 3T3-L1 cells. In the present study, we evaluated the effects of NPB on the proliferation and differentiation of white porcine preadipocytes into mature adipocytes.
