Liver cirrhosis is a scene profitable to the advance of hepatocellular carcinoma (HCC). The current work was engrossed to weigh the potential role of Cichorium intybus linn against thioacetamide (TAA)‐induced liver cirrhosis and their probable underlying biochemical and molecular mechanisms. farnesoid‐X‐receptor (FXR) expression, proliferating cell nuclear antigen (PCNA) immunoreactivity, and activated AMP protein kinase (pAMPK), sirtuin‐1 (SIRT1), and interleukin‐6 (IL6) levels were estimated in hepatic tissue by real‐time PCR, immunohistochemistry, and immunoassay, respectively. C. intybus linn supplementation caused a significant improvement in serum liver enzymes, albumin, bilirubin levels, tissues redox status and hepatic histological features in addition to decreased IL6 level, hydroxylproline content, and PCNA immunoreactivity. On contrary, increased pAMPK/SIRT1 levels and upregulated FXR gene expression were observed. C. intybus linn could feasibly protect against TAA‐induced hepatic damage, fibrosis, and cirrhosis by relieving oxidative stress and by interruption of the inflammatory pathway via AMPK/SIRT1/FXR signaling. Practical applications No specific therapies are available until now to target the underlying mechanisms for protection against liver diseases. Herbal protection is widely available and cheap with no side effect. Cichorium intybus linn, a natural supplement, is proved in this current work to have the potential of being hepatoprotectant, antioxidant, and anti‐inflammatory agents, thus reducing the risk of hepatic cirrhosis.

Lung diseases such as asthma, chronic obstructive pulmonary diseases, and pneumonia are causing many global health problems. The COVID-19 pandemic has directed the scientific community’s attention toward performing more research to explore novel therapeutic drugs for pulmonary diseases. Herein, gas chromatography coupled with mass spectrometry tentatively identified 44 compounds in frankincense ethanol extract (FEE). We investigated the antibacterial and antibiofilm effects of FEE against Pseudomonas aeruginosa bacteria, isolated from patients with respiratory infections. In addition, its in vitro immunomodulatory activity was explored by the detection of the gene expression of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), nitric oxide synthase (iNOS), cycloxygenase-2 (COX-2), and nuclear factor kappa-B (NF-κB) in lipopolysaccharide (LPS)-induced peripheral blood mononuclear cells (PBMC). In addition, its anticancer activity against the A549 lung cancer cell line and human skin fibroblast (HSF) normal cell line was studied. Moreover, the in vivo lung protective potential of FEE was explored histologically and immunohistochemically in mice using a benzo(a)pyrene induced lung damage model. FEE exhibited antibacterial and antibiofilm activities besides the significant inhibition of gene expression of TNFα, IL-6, and NF-κB. FEE also exerted a cytotoxic effect against A549 cell line. Histological and immunohistochemical investigations with morphometric analysis of the mean area percentage and color intensity of positive TNF-α, COX-2, and NF-κB and Bcl-2 reactions revealed the lung protective activity of FEE. This study outlined the promising therapeutic activity of oleoresin obtained from B. dalzielii in the treatment of different pulmonary diseases.

Doxorubicin (DOX) is an anticancer antibiotic which has various effects in human cancers. It is one of the commonly known causes of drug-induced nephrotoxicity, which results in acute renal injury. Adrenomedullin (ADM), a vasodilator peptide, is widely distributed in many tissues and has potent protective effects. Therefore, the current study aimed to examine the protective potential mechanisms of ADM against DOX-induced nephrotoxicity. A total of 28 male Wistar rats were randomized into four groups: control group, doxorubicin group (15 mg/kg single intraperitoneal injection of DOX), adrenomedullin + doxorubicin group (12 μg/kg/day intraperitoneal injection of ADM) 3 days prior to DOX injection and continuing for 14 days after the model was established, and adrenomedullin group. Kidney function biomarkers, oxidative stress markers, and inflammatory mediators (TNF-α, NLRP3, IL-1β, and IL-18) were assessed. The expressions of gasdermin D and ASC were assessed by real-time PCR. Furthermore, the abundances of caspase-1 (p20), Bcl-2, and Bax immunoreactivity were evaluated. ADM administration improved the biochemical parameters of DOX-induced nephrotoxicity, significantly reduced oxidative damage markers and inflammatory mediators, and suppressed both apoptosis and pyroptosis. These results were confirmed by the histopathological findings and revealed that ADM’s antioxidant, anti-inflammatory, anti-apoptotic, and anti-pyroptotic properties may have prospective applications in the amelioration of DOX-induced nephrotoxicity.
