Bacterial Lipase Neutralized Toxicity of Lipopolysaccharide on Chicken Embryo Cardiac Tissue.
It has been shown that near all organs, especially the cardiovascular system, are affected by bacterial lipopolysaccharide via the activation of Toll-like receptor signaling pathways. Here, we tried to find the blunting effect of bacterial lipase on lipopolysaccharide (LPS)-induced cardiac tissue toxicity in chicken embryos. 7-day fertilized chicken eggs were divided randomly into different groups as follows; Control, Normal Saline, LPS (0.1, 0.5 and 1 mg/kbw), and LPS (0.1, 0.5 and 1 mg/kbw) plus 5 mg/ml Lipase. On day 17, the hearts were sampled. The expression of genes such as GATA4, NKX2.5, EGFR, TRIF, and NF-ƙB was monitored using real-time PCR analysis. Using western blotting, we measured NF-ƙB protein level. Total antioxidant capacity, glutathione peroxidase, and Catalase activity were also studied. Microvascular density and anterior wall thickness were monitored in histological samples using H&E staining. High dose of LPS (1 mg/kbw) increased the expression of TRIF but not NF-ƙB compared to the control group (p < 0.05). We found a statistically significant reduction in groups that received LPS + Lipase compared to the control and LPS groups (p < 0.05). Western blotting revealed that the injection of Lipase could reduce LPS-induced NF-ƙB compared to the control group (p < 0.05). The expression of GATA4, NKx2.5, and EGFR was not altered in the LPS group, while the simultaneous application of LPS and Lipase significantly reduced GATA4, NKx2.5, and EGFR levels below the control (p < 0.05). We found non-significant differences in glutathione peroxidase, and Catalase activity in all groups (p > 0.05), while total antioxidant capacity was increased in groups that received LPS + Lipase. Anterior wall thickness was diminished in LPS groups and the use of both lipase and LPS returned near-to-control values (p < 0.05). Despite a slight increase in microvascular density, we found statistically non-significant differences in all groups (p > 0.05). Bacterial lipase reduces detrimental effects of LPS on chicken embryo heart induced via Toll-like receptor signaling pathway.Afsaneh Bagherzadeh, Hamidreza Vaziri, Fatemeh Sokouti Nasimi, Shahin Ahmadian, Adel Feyzi, Mehrdad Farhadi, Fariba Yahyavi, Behnam Hashemi, Reza Rahbarghazi, Mahdi Mahdipour

Arecoline suppresses RANKL-induced osteoclast differentiation in vitro and attenuates LPS-induced bone loss in vivo.
Areca nut has anti-inflammatory, antiparasitic, antihypertensive, and antidepressant properties. The pathological hallmarks of inflammatory joint diseases are an increased number of osteoclasts and impaired differentiation of osteoblasts, which may disrupt the bone remodeling balance and eventually lead to bone loss.Fei-Lan Liu, Chun-Liang Chen, Chien-Chih Lai, Chia-Chung Lee, Deh-Ming Chang
