Objective: Several factors contribute to the development of hypertension in patients with IgA nephropathy (IgAN). This study was conducted to find the relationships between baseline blood pressure (BP) and clinico-pathological findings in patients with IgAN and normal renal function. Design and Method: Clinico-pathological findings were analyzed in a total of 163 patients with IgAN and serum creatinine £ 1.1 mg/dL from The Kyung-Hee Cohort of Glomerulonephritis. The glomerular surface area (GSA) was determined using imaging analysis software. The serum and urine angiotensinogen (AGT) concentrations were measured using human ELISA kits.?Results: Mean serum creatinine concentration was 0.86 (0.5~1.1) mg/dL. Systolic BP was ≥ 130 mmHg in 72 patients (44%) and ≥ 140 mmHg in 42 (26%). Patients with systolic BP ≥ 130 mmHg as compared with those <130 mmHg had higher GSA and tubulointerstitial fibrosis and showed worse follow-up clinical findings: higher concentrations of serum creatinine, larger amount of proteinuria and lower levels of GFR. Systolic BP was positively correlated with age, baseline and follow-up proteinuria, serum uric acid concentrations and IgM deposit and negatively with follow-up GFR and the slope of change in 1/serum creatinine for 2 years, while it has no significant relationships with serum and urine AGT and 24 hour urinary sodium excretion. Conclusions: This study showed that systolic BP was associated with renal progression and pathological findings, glomerulomegaly and tubulointerstitial fibrosis, in patients with IgAN.

Proteins related to DNA replication have been proposed as cancer biomarkers and targets for anticancer agents. Among them, minichromosome maintenance (MCM) proteins, often overexpressed in various cancer cells, are recognized both as notable biomarkers for cancer diagnosis and as targets for cancer treatment. Here, we investigated the activity of cedrol, a single compound isolated from Juniperus chinensis, in reducing the expression of MCM proteins in human lung carcinoma A549 cells. Remarkably, cedrol also strongly inhibited the expression of all other MCM protein family members in A549 cells. Moreover, cedrol treatment reduced cell viability in A549 cells, accompanied by cell cycle arrest at the G1 phase, and enhanced apoptosis. Taken together, this study broadens our understanding of how cedrol executes its anticancer activity while demonstrating that cedrol has potential application in the treatment of human lung cancer as an inhibitor of MCM proteins.
