The objective of the present study was to determine suitability a swine breed with leptin resistance and predisposition obesity (the Iberian pig) as model for studies on metabolic syndrome type 2 diabetes. Thus, six sows had ad libitum access food enriched saturated fat (SFAD group; consumption estimated be 4.5 kg/animal/day) whilst four females acted controls were fed kg/animal/day commercial maintenance diet. After three months differential feeding, SFAD animals developed central obesity,...

Hutchinson-Gilford progeria syndrome (HGPS) is an extremely rare genetic disorder for which no cure exists. The disease characterized by premature aging and inevitable death in adolescence due to cardiovascular complications. Most HGPS patients carry a heterozygous de novo LMNA c.1824C > T mutation, provokes the expression of dominant-negative mutant protein called progerin. Therapies proven effective HGPS-like mouse models have yielded only modest benefit clinical trials. To overcome gap...

The effects of undernutrition during pregnancy on prenatal and postnatal development the offspring were evaluated in sows with obesity/leptin resistance. Females fed, from day 35 onwards, a diet fulfilling either 100% (group control, n=10) or 50% nutritional requirements underfed, n=10). In control group, maternal body weight increased (P<0.05) while it decreased remained steady underfed group. At days 75 100 gestation, plasma triglycerides lower but urea levels higher restricted than...

Three-dimensional bioprinting is a technology in constant development, mainly due to its extraordinary potential revolutionize regenerative medicine. It allows fabrication through the additive deposition of biochemical products, biological materials, and living cells for generation structures bioengineering. There are various techniques biomaterials or bioinks that suitable bioprinting. Their rheological properties directly related quality these processes. In this study, alginate-based...

Recently, the capacity of mesenchymal stem/stromal cells (MSCs) to migrate into damaged tissues has been reported. For MSCs be a promising tool for tissue engineering and cell gene therapy, it is essential know their migration ability according origin. However, little known about molecular mechanisms regulating porcine MSC chemotaxis. The aim this study was examine migratory properties in an inflammatory environment lines from different origins: subcutaneous adipose (SCA-MSCs), abdominal...

Maternal malnutrition during pregnancy, both deficiency and excess, induces changes in the intrauterine environment metabolic status of offspring, playing a key role growth, fitness/obesity appearance disorders postnatal life. There is increasing evidence that these effects may not be only limited to first generation descendants, offspring directly exposed challenges, but subsequent generations.

Studies of knockout (KO) mice with defects in the endolysosomal two-pore channels (TPCs) have shown TPCs to be involved pathophysiological processes, including heart and muscle function, metabolism, immunity, cancer, viral infection. With objective studying TPC2's roles for first time a large, more humanlike animal model, TPC2 KO pigs were produced using CRISPR-Cas9. A major problem CRISPR-Cas9 edit embryos is mosaicism; thus, we studied effect microinjection timing on mosaicism. Mosaicism...
