In summary, we have systematically characterized the interactome of the ALOX5 promoter, identifying several zinc finger proteins as novel potential ALOX5 gene regulators. Further, we have shown that the ALOX5 promoter can form DNA G-quadruplex structures, which may play a functional role in ALOX5 gene regulation. © 2020 The Authors.

In the current study, we prospectively evaluated dynamics of liver stiffness by transient elastography (TE) in patients with chronic HCV infection receiving DAA-based treatment. Patients (260) were enrolled in the German Hepatitis C-Registry (DHC-R), a national multicentre real-world cohort. Liver stiffness (LS) was assessed at baseline, end of treatment (EOT) and 24 weeks after EOT (FU24) by TE. Biochemical, virological and clinical data were obtained in parallel. In patients with SVR, there was a significant improvement of LS between baseline (median [range], 8.6 [1.7-73.5] kPa) and FU24 (7.9 [1.7-75 kPa]; P less then .0001) as well as between EOT (8.4 [1.7-73.5 kPa]) and FU24 [P less then .0001]. Stratified by fibrosis stage, patients classified into F4 had higher magnitude of LS reduction between BL (median [range], 25.1 [13.5-73.5] kPa) and FU24 (21.5 [3.1-75] kPa; P = .002) compared to those with F2-F3 (8.9 [7.1-12.4] kPa and 8.8 [4.2-29.1]; P = .060) or F0-F1 (5.3 [1.7-7] kPa and 5.2 [1.7-7.7]; P = .064). In cirrhotic patients, low platelets were significantly associated with lack of liver stiffness improvement, both at EOT (P = .018) and at FU24 (P = .012). LS significantly correlated wit
