Tissue growth in most fishes occurs by muscular hyperplasia and hypertrophy, which are influenced by different regulatory factors, such as myostatin. The current study evaluated the influence of cultivation in hapas and earthen ponds on the diameter of white muscle fibers and on the myostatin (MSTN-1) gene in GIFT and Supreme varieties of tilapia. Fish of both varieties were reared for 204 ... more

Intramammary infections are one of the main causes of productivity loss in dairy cows. To better understand the immune system response and to avoid the use of live animals, we validated the use of isolated bovine udder as an ex situ model. Six mammary glands were collected from cows ready for culling. Three udders were perfused with Tyrode's solution and three were not-perfused. During six ... more
Expression of lipid metabolism and myosin heavy chain genes was evaluated in skeletal muscle of pig’s genotypes submitted to different dietary digestible lysine contents. Fifty-two barrows and fifty gilts from three genotypes (G: Piau, Duroc and Pietrain crossbreds) were assigned to three dietary digestible lysine contents (DL: Low, Medium and High). Ten genes were ... more
Honey bees (Apis mellifera) are exposed to sublethal doses of insecticides, but little is known about insecticide effects on their survivorship associated to health-related gene expression. To test the effect of sublethal doses of clothianidin, imidacloprid and carbaryl on the lifespan and health of honey bees, workers were orally and topically exposed to LD5 doses ... more
Phosphate (Pi) unavailability is a growth-limiting factor for plants. Under Pi-limited conditions, plants activate molecular mechanisms for better acquisition and utilization of this nutrient. In maize, changes in the expression pattern of several Pi starvation-induced genes, including the A1 coding for dihydroflavonol 4-reductase (DFR) involved in ... more
Anopheles (Nyssorhynchus) darlingi is the primary vector of human malaria in South America. Immune responses in mosquito vectors of malaria are mainly regulated by genes of the Toll and IMD pathways through the transcription factors NF-kappa-β, Rel1 and Rel2, which are controlled by the negative regulatory genes ... more
Cotton has high adaptability to adverse conditions; however, one of the main factors causing production loss is water deficits. To adapt to these conditions, plants go through a series of changes, many of them driven by genes that are expressed to increase drought tolerance. We examined the expression profile of the MYB60 and GUSP1 genes, which ... more
Psidium guajava (guava) is a fruit tree of the Myrtaceae family of nutritional and economic importance and wide edaphoclimatic adaptation. For commercial orchard purposes, guava trees are derived from clonal propagation and the production cycle begins with drastic pruning. During its development the guava tree displays varied characteristics that may ... more
Alcohol dependence is a multifactorial inherited psychiatric disease that is difficult to diagnose and treat. Recent years have seen an increase in knowledge about molecular pathways and effect of proinflammatory cytokines on alcohol dependence. Understanding this pathology as an inflammatory condition opens the possibility of using new therapeutic agents to treat ... more
