Some effects of insect hormones on Na(^+), K(^+)-ATPase and fluid secretion by the malpighian tubules of locusta migratoria L [PDF]
A study has been made on the effects of insect hormones on fluid secretion by the Malpighian tubules of Locusta, and on the Na(^+), K(^+)- ATPase activity in microsomal preparations of the tubules.

Organoids in pediatric cancer research
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Biochemical, cytochemical localization and physiological studies on Malpighian tubules of Locusta Migratoria L. [PDF]
Specific inhibitors of protein kinase A (PKA), Rp-cAMP, protein kinase C (PKC), chelerythrine and staurosporine, and protein phosphatase 1 and 2A okadaic acid, inhibited fluid secretion whilst corpora cardiaca (CC) extract and cAMP were found to ...

Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

Proximal convoluted tubules of the rats kidney--a stereological analysis [PDF]
Background and Purpose: The aim of this work was to order quantitative parameters of the proximal convoluted tubules (PCT) in the normal rat kidney cortex. Volume density (VV), both surface and specific surface density toward interstitium (SVi and SVi/VV)

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Fibroblast growth factor 23 (FGF23) plays critical roles in phosphate handling and vitamin D metabolism in the kidney. However, the effector cells of FGF23 in the kidney remain unclear.

Studies on ion movement in malpighian tubules of locusta migratoria l. with particular reference to electrical events [PDF]
Intracellular microelectrodes have been used in conjunction with ion substitution, and agonists and inhibitors of known transport processes to investigate the mechanisms whereby ions cross the basal and apical cell membranes of the Malpighian tubules of ...

A technique to reduce fixation artifacts to kidney proximal tubules [PDF]
The preservation of proximal tubules in a state most closely resembling their in vivo morphology requires careful attention to fixation procedures. Conventional excision-immersion fixation is known to result in swelling of the cells lining proximal ...

The pre‐regenerative vascular niche (PVN) is essential for nerve repair, yet its endothelial blueprint remains unclear. We identified angiogenic ECs (AECs) as the dominant pre‐regenerative subset and found that antler blood–derived exosomes (AB‐EXO) promote repair via IMP3.
