Drosophila as a model for the Anopheles Malpighian tubule
The insect Malpighian tubule is involved in osmoregulation, detoxification and immune function, physiological processes which are essential for insect development and survival. As the Malpighian tubules contain many ion channels and transporters, they could be an effective tissue for targeting with …

A pharmacological study of signal transduction mechanisms controlling fluid reabsorption and Ion transport in the locust rectum
… is typical of many insects and consists of the Malpighian tubules and the hindgut. The Malpighian tubules secrete a primary isosmotic urine rich in KC1 and low in Na+ that contains most small hemolymph solutes, waste products and toxic plant chemicals. The hindgut (ileum and rectum) is …

Mechanisms Underlying Variation in Insect Chill Tolerance: The Role of Ion and Water Transport
… modifications by comparing the hindgut and Malpighian tubule transcriptomes of warm- and cold-acclimated individuals. Cold acclimation modified the expression of hindgut and Malpighian tubule ion transporters, and hindgut structural (cytoskeletal and cell junction) genes. Rectal …

An electrophysiological study of ion transport across the isolated perfused malpighian tubule of Onymacris plana
… of the ionic and electrical gradients across the Malpighian tubules of Onymacris plana is fundamental to the understanding of the transport mechanisms of fluid across the basolateral and apical membranes. Until now no one has investigated the isolated perfused Malpighian tubule of Onymacris plana …

The Effect of Heterochromat in on Genes Located Within Heterochromatic Areas of Standard Chromosomes of Drosophila Melanogaster
… exhibits a maternal effect, that is, larval Malpighian tubules (MPT) are colorless in light offspring if their mothers are lt/lt, but do exhibit some color if the mother is lt+/lt (Beadle 1937). The yellow pigment found in the MPT is primarily riboflavin (Nickla 1972a) which can be measured …

A P-glycoprotein-like mechanism in the nicotine-resistant insect, Manduca sexta.
… demonstrated positive immunolabelling of the Malpighian tubules of M. sexta and R. prolixus and at the blood-brain barrier of the central nervous systems of M. sexta and P. americana. To assess the extent of P-glycoprotein involvement at the blood-brain barrier of M. sexta, I took advantage of …

The effect of mTOR inhibitor rapamycin on a dietary Drosophila melanogaster model of calcium oxalate nephrolithiasis
… on the area of calcium oxalate concretion in the Malpighian tubules of a Drosophila melanogaster fed a lithogenic diet containing 0.1% sodium oxalate.

An investigation into the physiology of urate pellet excretion by Parcoblatta fulvescens (Saussure and Zehntner) (Dictyoptera: Blattellidae)
… in the middle and proximal regions of the Malpighian tubules of <i>P. fulvescens</i>, <i>Shawella couloniana</i> and <i>Symploce hospes</i>. These spherules are discharged into the hindgut in sufficient quantities to obscure the presence of food residues. The significance of formed urate …

Salinity Responsiveness of Aquaporins in Osmoregulatory Organs of Larval Mosquito Aedes Aegypti
… with the most AaAQPs expression found in the Malpighian tubules and anal papillae when compared to other osmoregulatory organs assessed in this study. Changes in transcript and protein abundance were observed in AaAQP1, AaAQP3, AaAQP4, AaAQP5, and AaAQP6 suggesting that the larvae modulate …

Manipulation of second messengers by ectopic expression of receptors in transgenic Drosophila
… AMP (cAMP) and calcium (Ca2+) in the renal (Malpighian) tubule of the genetic model organism, Drosophila melanogaster. The importance of the second messengers cGMP, cAMP and Ca2+ in control of fluid transport makes the Malpighian tubule an ideal testbed for such technology. The actions of …

The Internal Anatomy and Histology of Adult <em>Antricola mexicanus</em> Hoffman (Acari: Argasidae)
… function. No rickettsiae were visible in the malpighian tubules. The paired coxal organs consist of a tubular, alveolar structure, a sacculus, and a duct leading to the external opening between coxae I and II. No cuticular structure supports the lumen of the alveolar structure, and the …
