Summary
The mammalian target of rapamycin (mTOR) pathway regulates kidney cell growth and survival. Dysregulation of mTOR signaling contributes to kidney diseases, but targeting it may offer therapeutic benefits.
Area of Science:
- Nephrology
- Molecular Biology
- Biochemistry
Background:
- Mammalian target of rapamycin (mTOR) is a key kinase regulating cellular processes.
- mTOR signaling is vital for maintaining kidney homeostasis under normal conditions.
- Aberrant mTOR activation is implicated in various kidney pathologies.
Purpose of the Study:
- To review the role of mTOR signaling in kidney physiology and injury.
- To explore the therapeutic potential of targeting mTOR in kidney diseases.
Main Methods:
- Literature review of recent studies on mTOR signaling in renal contexts.
- Analysis of mTOR's involvement in cellular homeostasis, regeneration, and disease progression.
Main Results:
- Physiologic mTOR activation supports podocyte and tubular cell health.
- Activated mTOR in AKI promotes renal repair.
- Constitutive mTOR activation drives kidney diseases like glomerular hypertrophy, fibrosis, and cancer.
Conclusions:
- mTOR signaling plays a dual role in kidney health and disease.
- Targeting mTOR presents a promising therapeutic strategy for kidney diseases.

3.9K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

4.1K
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a...

Acute kidney injury (AKI) causes are categorized into three primary categories based on the location of the injury: prerenal, intrarenal (or intrinsic), and postrenal causes. This classification guides clinical management and illustrates how different pathways can impair kidney function.Etiology and Pathophysiology of Acute Kidney Injury1. Prerenal causesEtiology: Prerenal Acute Kidney Injury, the most common type, occurs when reduced blood flow to the kidneys decreases filtration capacity...

Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

3.6K
The kidneys are intricate organs with millions of working units known as nephrons. Each nephron features two major structures: the renal corpuscle, which facilitates blood plasma filtration, and the renal tubule, which handles the glomerular filtrate. Blood supply is directly linked to the nephrons. The renal corpuscle consists of the glomerulus, a capillary network, and the Bowman's capsule, a double-walled epithelial structure that encases the glomerulus. The filtering of blood plasma...

The glomerulus and Bowman's capsule are two essential components of the nephron, which is the functional unit of the kidney. These microscopic structures play a critical role in the process of blood filtration to produce urine.
Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous...
