[Q]: The epithelial-mesenchymal transition (EMT) is the process where cells lose their epithelial features and acquire properties of typical mesenchymal cells. The dissociation of tumor cells due to changes in cell-cell adhesion is one of the key principles of tumor invasion and EMT. Thus, the knowledge of the molecular features of EMT in keratocyst odontogenic tumor (KOT) can provide useful markers to aid in the diagnosis and prognosis and perhaps contribute to an alternative therapeutic approach as it shows an aggressive clinical behavior and high recurrence rates. This study aimed to evaluate the EMT in KOT by the immunoexpression of E-cadherin, N-cadherin, Snail, and Slug and comparing to radicular cysts and dental follicles.', 'Thirty-two KOTs, 15 radicular cysts, and 08 dental follicles were used for immunohistochemistry, evaluating the extent, intensity, labeling pattern, cellular compartment in the epithelium and stroma, and the presence of inflammation.', 'E-cadherin was preserved in most cases of keratocystic odontogenic tumor. N-cadherin was increased in the tumor epithelium, a result that was positively correlated with the heterogeneous and nuclear immunoexpression of Slug in the epithelium; Slug also correlated with high Snail immunoexpression. N-cadherin was positively correlated with Slug in the stroma of keratocystic odontogenic tumors.

[Q]: In non-alcoholic fatty liver disease (NALFD), it has often been assumed that an elevation in serum ferritin is likely related to inflammation rather than iron overload.', 'Patients referred with NAFLD were entered into a clinical study of phlebotomy therapy. A liver biopsy with liver iron concentration was done at entry and 6 months after phlebotomy (n = 56) until the patient had a low serum ferritin or developed anemia. Serum ferritin was compared to liver iron concentration, ESR, CRP, BMI and grade of inflammation on liver biopsy.', 'Iron removed by phlebotomy in NAFLD correlated with the decrease in serum ferritin (r = 0.57, p = 0.0014) and liver iron concentration (r = 0.57, p = 0.0013). There was no significant correlations between serum ferritin and ESR, CRP or grade of liver inflammation.

[Q]: Patients with alcoholic liver disease (ALD) display inflammation of the subcutaneous adipose tissue (SAT) which correlates with liver lesions. We examined macrophage markers and polarization in the SAT of alcoholic patients and adipokine expression according to liver inflammation; we studied the consequences of alcohol withdrawal.', 'Forty-seven patients with ALD were prospectively included. SAT and blood samples were collected at inclusion and after 1week of alcohol withdrawal. Pro-inflammatory cytokines/chemokines, inflammasome components and products, adipokine expression levels, macrophage markers and polarization in liver and SAT samples were assessed by RT-PCR arrays.', 'mRNA expression level of chemokines (IL8, semaphorin 7A) correlated with hepatic steatosis in both liver and SAT. Liver expression of inflammasome components (IL1, IL18, caspase-1) and SAT IL6 and CCL2 correlated with liver damage. In patients with mild ALD, 1week of alcohol withdrawal was sufficient to decrease expression level of total macrophage markers in the adipose tissue, to orient adipose tissue macrophages (ATM) towards an anti-inflammatory M2 phenotype and to decrease the mRNA expression of cytokines/chemokines (IL18, CCL2, osteopontin, semaphorin 7A). In patients with severe ALD, 1week of abstinence was also associated with an increase in CCL18 expression.
