ENaC also mediates aldosterone-dependent sodium reabsorption in the distal nephron of the kidney, thus regulating blood pressure. (thermofisher.com)
The majority of the filtered load is reabsorbed by the proximal tubule, but significant amounts are also absorbed in the loop of Henle and the early distal nephron. (medscape.com)
Light chains saturate the reabsorptive capacity of the proximal tubule, reach the distal nephron, and combine with filtered proteins and Tamm-Horsfall mucoprotein (secreted by cells of the thick ascending limb of Henle) to form obstructive casts. (msdmanuals.com)

Some diseases of the nephron predominantly affect either the glomeruli or the tubules. (wikipedia.org)
This is because capillaries, those tiniest and most numerous of all the blood vessels, get leaky in the absence of ample vitamin C. Easily-bleeding gums are a visible example of this, but easily-leaking glomeruli (part of the nephron ) are a greater, hidden, but similar problem. (doctoryourself.com)

It comprises low molecular proteins such as beta-2 microglobulin, which in normal conditions are completely reabsorbed by proximal tubules. (medscape.com)
Overflow proteinuria is most commonly associated with increased production of abnormal low molecular weight proteins (eg, light chains in multiple myeloma, myoglobin in rhabdomyolysis) that exceeds the reabsorption capacity of the tubules, leading to spilling of the protein into the urine.

These low molecular proteins can be toxic to the tubules and can cause acute kidney injury. (medscape.com)

Nephrons have two lengths with different urine-concentrating capacities: long juxtamedullary nephrons and short cortical nephrons. (wikipedia.org)
Up to 90% of the filtered load is reabsorbed by the nephron, 60% in the proximal tubule, and the remainder in the thick ascending limb of the loop of Henle, the connecting tubule, and the cortical collecting duct. (medscape.com)

Long-term activation of protein kinase c causes chronic Na/H antiporter stimulation in cultured proximal tubule cells. (jci.org)
To examine the role of protein kinase C as a chronic regulator of proximal tubule Na/H antiporter activity, the effect of phorbol 12-myristate 13-acetate (PMA) on the Na/H antiporter was studied in cultured proximal tubule cells. (jci.org)
Short-term activation of protein kinase C by 5 min exposure to PMA caused an acute increase in Na/H antiporter activity that was not prevented by cycloheximide or actinomycin D and did not persist 24 h later. (jci.org)
Long-term activation of protein kinase C by 2 h exposure to PMA caused a dose-dependent increase in Na/H antiporter activity 24 h later. (jci.org)
This latter effect was due to protein kinase C activation in that it was inhibited by sphingosine and was not seen with 4 alpha-PMA, an inactive analogue. (jci.org)
In conclusion, short-term activation of protein kinase C leads to a transient increase in Na/H antiporter activity that is independent of transcription and translation, whereas long-term activation of protein kinase C causes a persistent increase in antiporter activity that is dependent on transcription and translation and is associated with increased mRNANa/H abundance.
