Abstract

Insights

Quercetin protects against doxorubicin-induced kidney injury in mice by reducing inflammation and improving renal function. This natural compound may offer a therapeutic strategy for nephrotoxicity.

Area of Science:

  • Pharmacology
  • Nephrology
  • Biochemistry

Background:

  • Doxorubicin (anticancer drug) causes kidney damage (nephrotoxicity), necessitating research into protective agents.
  • Mouse models of doxorubicin-induced nephropathy are crucial for preclinical studies.
  • Quercetin is investigated for its potential renoprotective effects.

Purpose of the Study:

  • To evaluate the protective effect of quercetin against doxorubicin-induced kidney injury in a mouse model.
  • To elucidate the underlying mechanisms of quercetin's action on renal function and cellular pathways.

Main Methods:

  • Doxorubicin-induced nephropathy model in C57BL/6 mice.
  • Assessment of kidney function markers (serum and urine).
  • Histopathology (H&E), electron microscopy, immunohistochemistry, RT-qPCR, ELISA, Western blot, and molecular docking.

Main Results:

  • Quercetin treatment improved kidney function and reduced tissue damage and fibrosis.
  • Mitochondrial structure and apoptotic protein levels (Bax, Bcl-2) were normalized by quercetin.
  • Quercetin downregulated Ang II, inflammatory factors, and modulated the AKT1/Raf/MEK/ERK pathway.

Conclusions:

  • Quercetin demonstrates significant renoprotective effects against doxorubicin-induced nephropathy.
  • The protective mechanism involves regulating inflammatory factors and the AKT1/Raf/MEK/ERK signaling pathway.
  • Quercetin shows promise as a therapeutic agent for mitigating doxorubicin-induced kidney injury.

mTOR Signaling and Cancer Progression

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.

MAPK Signaling Cascades01:07

MAPK Signaling Cascades

Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...

PI3K/mTOR/AKT Signaling Pathway

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...

Inhibition of Cdk Activity02:34

Inhibition of Cdk Activity

The orderly progression of the cell cycle depends on the activation of Cdk protein by binding to its cyclin partner. However, the cell cycle must be restricted when undergoing abnormal changes. Most cancers correlate to the deregulated cell cycle, and since Cdks are a central component of the cell cycle, Cdk inhibitors are extensively studied to develop anticancer agents. For instance, cyclin D associates with several Cdks, such as Cdk 4/6, to form an active complex. The cyclin D-Cdk4/6 complex...

Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
