Loss of SAV1 in Kidney Proximal Tubule Induces Maladaptive Repair after Ischemia and Reperfusion Injury.

Kidney ischemia and reperfusion injury (IRI) is a significant contributor to acute kidney injury (AKI), characterized by tubular injury and kidney dysfunction. Salvador family WW domain containing protein 1 (SAV1) is a key component of the Hippo pathway and plays a crucial role in the regulation of organ size and tissue regeneration. However, whether SAV1 plays a role in kidney IRI is not investigated.

2-Mercaptoethanol protects against DNA double-strand breaks after kidney ischemia and reperfusion injury through GPX4 upregulation.

Background: Kidney ischemia reperfusion injury (IRI) is characterized by tubular cell death. DNA double-strand breaks is one of the major sources of tubular cell death induced by IRI. 2-Mercaptoethanol (2-ME) is protective against DNA double-strand breaks derived from calf thymus and bovine embryo.

SNU-333 Cells as an Appropriate Cell Line for the Orthotopic Renal Cell Carcinoma Model.

: To investigate a feasible candidate for an appropriate cell line for the orthotopic renal cell carcinoma (RCC) model. Normal human proximal tubule cells (HK-2) and RCC cells were used for MTT assay, Western blotting, sphere-forming assay, and orthotopic injection of BALB/c-nude mice. Immunohistochemistry was adopted in tissue arrays and orthotopic tumors.

Anti-cancer effects of the aqueous extract of Orostachys japonica A. Berger on 5-fluorouracil-resistant colorectal cancer via MAPK signalling pathways in vitro and in vivo.

Ethnopharmacological Relevance: Orostachys japonica A. Berger, also known as Wa-song in Korea, has traditionally been used as a folk medicine, but the potential anti-cancer effects of aqueous extract of Orostachys japonica (OJe) have not yet been thoroughly investigated.

Aim Of The Study: To evaluate the anti-cancer effects of OJe, its possible mechanisms of action were investigated in 5-fluorouracil (5-FU) resistant SNU-C5/5-FUR colorectal cancer cells.

Cisplatin nephrotoxicity is induced via poly(ADP-ribose) polymerase activation in adult zebrafish and mice.

Cisplatin is a well-known chemotherapy medication used to treat numerous cancers. However, treatment with cisplatin in cancer therapy has major side effects, such as nephrotoxic acute kidney injury. Adult vertebrate kidneys are commonly used as models of cisplatin-induced nephrotoxic acute kidney injury.

Yeast Extract Induces Apoptosis and Cell Cycle Arrest via Activating p38 Signal Pathway in Colorectal Cancer Cells.

The microbiome has recently become a key interest for cancer research. Anti-tumor effects of reinforced clostridium media (RCM) were investigated for all ingredients of RCM, which showed that yeast extract could be a candidate for this phenomenon. MTT assay, cell counting, cell death analysis, cell cycle analysis, and Western blotting were done on colorectal cancer cells with or without 5-fluorouracil resistance (SNU-C5 and SNU-C5/5-FUR).

Cyclosporin A aggravates hydrogen peroxide-induced cell death in kidney proximal tubule epithelial cells.

Cyclosporin A (CsA) does not only exert a toxic effect on kidney parenchymal cells, but also protects them against necrotic cell death by inhibiting opening of mitochondrial permeability transition pore. However, whether CsA plays a role in hydrogen peroxide-induced kidney proximal tubular cell death is currently unclear. In the present study, treatment with CsA further increased apoptosis and necrosis in HK-2 human kidney proximal tubule epithelial cells during exposure to hydrogen peroxide.

Yeast extract inhibits the proliferation of renal cell carcinoma cells via regulation of iron metabolism.

The microbiome has recently attracted research interest in a variety of subjects, including cancer. In the present study, it was determined that reinforced clostridium media (RCM) for microbiome culture, exerts antitumor effects on renal cell carcinoma cells when compared to the microbiome 'X'. The antitumor effects of RCM were investigated for all ingredients of RCM, and the results revealed that yeast extract could be a candidate for the ingredient driving this phenomenon.
