Histological and functional renal alterations caused by Bothrops alternatus snake venom: expression and activity of Na+/K+-ATPase.

Background: Acute renal failure is a serious complication of human envenoming by Bothrops snakes. The ion pump Na+/K+-ATPase has an important role in renal tubule function, where it modulates sodium reabsorption and homeostasis of the extracellular compartment. Here, we investigated the morphological and functional renal alterations and changes in Na+/K+-ATPase expression and activity in rats injected with Bothrops alternatus snake venom.

A transcriptomic analysis of gene expression in the venom gland of the snake Bothrops alternatus (urutu).

Background: The genus Bothrops is widespread throughout Central and South America and is the principal cause of snakebite in these regions. Transcriptomic and proteomic studies have examined the venom composition of several species in this genus, but many others remain to be studied. In this work, we used a transcriptomic approach to examine the venom gland genes of Bothrops alternatus, a clinically important species found in southeastern and southern Brazil, Uruguay, northern Argentina and eastern Paraguay.

Transcriptome analysis of the oil-rich seed of the bioenergy crop Jatropha curcas L.

Background: To date, oil-rich plants are the main source of biodiesel products. Because concerns have been voiced about the impact of oil-crop cultivation on the price of food commodities, the interest in oil plants not used for food production and amenable to cultivation on non-agricultural land has soared. As a non-food, drought-resistant and oil-rich crop, Jatropha curcas L.
