Colostrum is produced by the mammary gland for the first few days following birth and is a rich natural source of macro- and micro-nutrients, immunoglobulins, and peptides with anti-microbial, immune modulatory and/or growth-factor activity [...]

ABSTRACT Conditions characterized by high levels of glucocorticoids are associated with poor growth. Serum somatomedin or insulin-like growth factor activity measured by cartilage bioassay systems is low, but is generally not accompanied by a fall in somatomedin concentration. Hydrocortisone and a synthetic analogue, dexamethasone, impaired the serum stimulated "in vitro" 35S sulphate and 3H-thymidine incorporation in porcine rib cartilage at physiological concentrations. Hydrocortisone added at a concentration of 0,1 μg/ml decreased the potency of normal serum to 50 % of controls. Dexamethasone was at least 10 times more potent. Removal of "in vitro" or "in vivo" administered hydrocortisone with dextran-coated charcoal restored the sulphate and thymidine activity to normal. We conclude that physiological amounts of glucocorticoids inhibit the "in vitro" porcine cartilage metabolism. Glucocorticoid administration "in vivo" does not abolish the activity of the cartilage stimulating effect of serum but affects cartilage metabolism directly or by the induction of locally produced inhibitors of cartilage metabolism.

The aim of this study was the investigation of the circulating concentration of IGF-1 in female dogs with spontaneous mammary tumours. The study was performed on 34 female dogs undergoing surgery due to spontaneously occurring mammary gland tumours (24 malignant and 10 benign) and 10 clinically healthy fe-male dogs. The serum concentrations of IGF-1 were determined by specific ELISA Kit assay. The mean con-centrations of IGF-1 were significantly higher (P < 0.05) both in dogs with malignant (173.35 ± 120.45 ng/ml) and benign (130.58 ± 59.0 ng/ml) mammary tumours than in healthy controls (117.45±71.0 ng/ml). In the group of female dogs with mammary carcinomas, the mean concentration of IGF-1 gradually increased from 132.85 ± 65.64 ng/ml in dogs with grade 1 tumours to 317.74 ± 119.25 ng/ml in those with grade 3 tumours, and significant differences (P < 0.05) were found among dogs with various grade tumours. These findings suggest that circulating IGF-1 may play an important role in the pathogenesis of canine mammary tumour. Moreover, high IGF-1 levels may reflect tumour cell differentiation into a more aggressive phenotype. .

The skin acts as the primary defense organ that protects the body from the external environment. Skin cancer is one of the most common cancers in the world. Skin carcinogenesis is usually caused by cell degeneration due to exposure to ultraviolet (UV) radiation, which causes changes in various signaling networks, disrupting the homeostasis of single skin cells. In this review, we summarize the roles of nicotinamide adenine dinucleotide phosphate oxidase (NOX) and epidermal growth factor receptor (EGFR) in UV-induced skin carcinogenesis. Furthermore, we describe the crosstalk that exists between NOX, EGFR, and protein tyrosine phosphatase κ and its oncogenic downstream signaling pathways. Chemoprevention is the use of chemical compounds to recover the healthy status of the skin or delay cancer development. Current evidence from in vitro and in vivo studies on chemopreventive phytochemicals that target NOX, EGFR, or both, as major regulators of skin carcinogenesis will also be discussed.
