Summary
MicroRNAs regulate human genes and are implicated in kidney diseases. Targeting microRNAs offers potential therapies for renal pathologies, but safety concerns require further study.
Area of Science:
- Molecular Biology
- Genetics
- Nephrology
Background:
- MicroRNAs (miRNAs) are small, noncoding RNA molecules regulating gene expression post-transcriptionally.
- Deregulation of miRNAs is linked to various human kidney diseases.
- miRNAs play crucial roles in fundamental biological processes.
Purpose of the Study:
- To summarize the role of miRNAs in renal glomerular and tubular pathologies.
- To highlight miRNA involvement in diabetic nephropathy, acute kidney injury, and electrolyte/blood pressure regulation.
- To discuss the therapeutic potential and challenges of miRNA-based treatments for kidney diseases.
Main Methods:
- Literature review and synthesis of current knowledge on miRNA functions in kidney diseases.
- Focus on specific renal pathologies: diabetic nephropathy, acute kidney injury, Ca++ imbalance, and distal tubule function.
- Analysis of therapeutic strategies involving miRNA manipulation.
Main Results:
- miRNAs are implicated in mesangial cell and podocyte dysfunction in diabetic nephropathy.
- miRNAs influence proximal tubular cell survival in acute kidney injury.
- miRNAs are involved in ion transport and blood pressure regulation in renal tubules.
- Identification of miRNA targets offers potential therapeutic avenues.
Conclusions:
- miRNA deregulation is a significant factor in kidney disease pathogenesis.
- miRNA-based therapies show promise for treating renal diseases by regulating gene networks.
- Challenges remain regarding target specificity and safety for clinical application.

MicroRNA (miRNA) are short, regulatory RNA transcribed from introns—non-coding regions of a gene—or intergenic regions—stretches of DNA present between genes. Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After...

01:29Renal Regulation of Acid-Base Balance
1.7K
Metabolic reactions in the body produce nonvolatile acids, such as sulfuric acid, which generate an acid load of approximately 1 mEq of H+ per kilogram of body weight daily. Excreting H+ in the urine is essential to balance this acid load.
In the kidneys, cells within the proximal convoluted tubules (PCT) and the collecting ducts secrete hydrogen ions (H+) into the tubular fluid. Specifically, in the PCT, Na+/H+ antiporters secrete H+ while reabsorbing Na+.
However, the intercalated cells in...

36.1K
The renin-aldosterone system is an endocrine system which guides the renal absorption of water and electrolytes, thus managing blood pressure and osmoregulation. Activation of the system begins in the kidneys with a small cluster of cells adjacent to the afferent and efferent blood vessels of the renal corpuscle. As the nephrons are filtering blood, juxtaglomerular cells monitor blood pressure. If they detect a decrease in pressure, they release the hormone renin into the bloodstream.

02:24Regulation of Expression Occurs at Multiple Steps
26.4K
Gene expression can be regulated at almost every step from gene to protein. Transcription is the step that is most commonly regulated. This involves the binding of proteins to short regulatory sequences on the DNA. This association can either promote or inhibit the transcription of a gene associated with the respective sequence.
Transcription results in the generation of precursor (pre-mRNA) that consists of both exons and introns, which needs further processing before being translated to a...
