The protein lysates were separated using SDS-PAGE and transferred to PVDF membranes and blocked with 5% skim milk or 3% bovine serum albumin (BSA). A recent study showed that GOLPH3 is upregulated in neuroblastoma N2A cells upon oxygen-glucose deprivation and reoxygenation to promote stress-related autophagy, ROS production, and apoptotic cell death [30]. This study investigated whether GOLPH3 is associated with endotoxemia-induced hepatic and renal injury. Taken together, GOLPH3 plays a crucial role in the development and progression of acute liver and kidney injury by promoting Golgi stress and increasing inflammatory response and apoptosis, suggesting GOLPH3 as a potential therapeutic target for endotoxemia-induced tissue injury. 2016;274:33053. The authors declare no competing interests. Finally, the sections were mounted and examined using a CKX41 light microscope (Olympus). Using in vitro LPS-treated hepatocytes and renal tubular cells, we consistently found that GOLPH3 is markedly increased, accompanied with the induction of Golgi stress and pro-inflammatory mediators (Tnf, IL-6, and IL-1). Too much iron can damage the liver, sometimes causing cirrhosis. What Is the Function of the Liver? | Healthy Living Nat Rev Gastroenterol Hepatol. The majority of the substances that are ingested, and subsequently digested, are absorbed from the lumen of the small intestines and passed to the liver by way of the hepatic portal vein. Cite this article. The multiple cellular functions of the oncoprotein Golgi phosphoprotein 3. As previously reported, GOLPH3 expression is upregulated in oxidative injury and various pathologies [18, 29, 30]. This condition causes an excess of iron to build up in the body. However, the pathogenic mechanisms of GOLPH3 and Golgi stress are still controversial. The 10% formalin-fixed liver and kidney tissues were embedded in paraffin and sectioned at 5m of thickness. GOLPH3 directly interacts with phosphatidylinositol 4-phosphate (PtdIns4P), and tightly binds to unconventional myosin 18A (MYO18A) to create a tensile force required for vesicle budding and anterograde trafficking and maintenance of the Golgi morphology [25, 26]. What is cirrhosis of the liver? Immunol Rev. Conversely, the downregulation of GOLPH3 significantly suppressed LPS-induced Golgi stress and inflammatory mediators (Tnf, IL-6, Mcp1, and Nos2), and reversing apoptotic cell death. Functions of the liver The liver regulates most chemical levels in the blood and excretes a product called bile. In fact, some dietary supplements can actually cause harm to the liver by leading to drug-induced injury and should thus be . 8 Healthy Foods for Your Liver - Cleveland Clinic Liu SF, Malik AB. Liver | Functions, Diseases & Treatments | Britannica Over time, liver disease can cause cirrhosis (scarring). Shaped like a cone, the liver is a dark reddish-brown organ that weighs about 3 pounds. Healthline Media does not provide medical advice, diagnosis, or treatment. This meets the cystic duct and then becomes the common bile duct. The extent of liver or kidney damage was evaluated and graded as described in the method section, while GOLPH3-positive cells/high power field (HPF) were assessed and counted (n=35). It contains several parts, including the liver hilum, that allows it to function and interact with other parts of the body. Downregulation of GOLPH3 ameliorates the Golgi stress response through inhibition of AKT/NF-B signaling and suppresses inflammatory response and apoptotic cell death. Multiple organ dysfunction is a common feature found in the pathogenesis of PAMP- or DAMP-induced hyper-inflammatory processes in sepsis [7, 8]. Compared to the rest of the body, the liver has a significant amount of blood flowing through it an estimated 13 percent of the bodys blood is in the liver at any given time. 2020;12:2802.

Its most commonly spread by contact with blood containing the hepatitis C virus in it, which includes sharing contaminated needles to inject drugs or apply tattoos. Increasing evidence suggests that the Golgi apparatus is a sensor and common downstream effector of stress signals in cell death pathways [18, 19]. The results demonstrated that LPS treatment induced the phosphorylation of AKT, IB, and NF-B p65, while GOLPH3 knockdown significantly reduced the phosphorylation (Fig. The liver is a unique organ due to its dual blood supply from the portal vein (approximately 75% . The liver starts growing back by having the existing cells enlarge. LPS-treated cells increased pro-inflammatory cytokines (Tnf, IL-1, and IL-6), which may be associated with GOLPH3 induction (Fig. 2021;165:24353. Your liver is your bodys largest solid organ. The protein and mRNA levels of GOLPH3 were significantly increased in FL83B and HK-2 cells in a time-dependent manner after LPS treatment (Fig. 8. Nat Rev Nephrol. The liver has been known to regenerate completely after as many as 12 partial liver removal surgeries. NAD(H)-loaded nanoparticles for efficient sepsis therapy via modulating immune and vascular homeostasis. Albumin Test: Albumin is a protein produced by the liver. The treatment involves surgical removal, Your outlook and treatment options for liver cancer depend on a variety of factors, including how far it has spread. The data are expressed as the meanSEM. The Golgi structure, ribbon-like stack formation are coordinated by resident Golgi matrix proteins such as Golgi reassembly-stacking protein 1 and 2 (GRASP65 and GRASP55, respectively), and Golgins (GM130 and Golgin-45) [39, 40]. The sections were blocked using 10% normal horse serum and incubated with a primary antibody against GOLPH3 (Proteintech Group, Chicago, IL, USA) at 4C overnight. Nat Cell Biol. Golgi phosphoprotein 3 (GOLPH3) promotes hepatocellular carcinoma progression by activating mTOR signaling pathway. Liver Function Tests: Purpose and Procedure - Healthline Wild-type male C57BL/6 mice (810 weeks) were purchased from KOATECH Co. (Pyeongtaek, South Korea) and maintained in the animal facility at Gyeongsang National University. These findings indicate that GOLPH3 directly mediates hepatic induction of pro-inflammatory cytokines and apoptosis through AKT/NF-kB signaling pathway. Cirrhosis is a late-stage liver disease in which healthy liver tissue is replaced with scar tissue and the liver is permanently damaged. A, B After transfection of GOLPH3 siRNA for 24h, the HK-2 cells were treated with LPS for 8h, and examined relative mRNA levels of Golph3 and pro-inflammatory mediators (Tnf, IL-6, Mcp1, and Nos2) using real-time PCR analysis. Google Scholar. Lancet 2020;395:20011. Recently, a trimodal distribution is prominent with reduced magnitude in the two early peaks and a third uprising peak 23 months after sepsis [5]. The liver performs many functions like removing toxic (harmful) wastes from the blood, removing old red blood cells, helping in digestion by breaking down fats, helping in controlling and storing blood sugar, it produces proteins needed for the body and helping in blood clotting. The liver turns the toxic ammonia into a substance called urea. 7F). (n.d.). Li Y, Zhang H, Long W, Gao M, Guo W, Yu L.

The livers major functions are in the metabolic processes of the body. GOLPH3 exhibits diverse cellular functions such as maintenance of Golgi structure, secretory and trafficking pathways, regulation of organelle crosstalk, and related signaling pathways [18, 24]. However, the molecular basis for Golgi stress and its role in the disease progression remain largely unknown. If left untreated, the condition can cause liver scarring and affect liver tissue. Hydrogen sulfide treatment reduces Golgi stress-induced apoptotic cell death and oxidative stress and ameliorates skeletal muscle atrophy in mice [47]. Results Probl Cell Differ. Extra bile is stored in the gallbladder. The PI3K/AKT has been identified as an upstream kinase for NF-B activation, and acts indirectly by phosphorylating IB, which in turn dissociates IB from the NF-B complex, leading to the transcriptional activation of inflammatory mediators [50, 51]. 2021;53:40721. The liver is the largest and perhaps the most complex organ in the body. These findings indicate that LPS-induced endotoxemia promotes Golgi stress and inflammatory response, which exacerbates liver and kidney injury.
