Liver cancer is the most lethal form of cancer and carries a high risk of death around the world. Goniothalamin (GTN) is a styryl-lactone that possesses antiproliferative and apoptotic activity. The molecular action of GTN is not yet fully evaluated. Thus, our research has been intended to assess the chemopreventive and apoptotic activities of diethylnitrosamine (DEN)-induced hepatocellular carcinoma (HCC) in rats. Rats were separated into 4 groups: control, DEN only, DEN + GTN (30 mg/kg bw), and GTN (30 mg/kg bw) alone. We evaluated body weight, liver weight, tumor incidence, hepatic toxic markers, antioxidants, inflammatory cytokines, histopathology, immunohistochemistry, and Western blot studies. DEN lessened body weight, antioxidants, and apoptosis, whereas it elevated tumor incidence, toxic markers, cytokines, and Bcl-2 expression. GTN treatment maintains body weight, liver weight, and antioxidant levels, and it also prevents tumor incidence, oxidative stress, toxic markers, pro-inflammatory cytokines, and histological changes. It triggers apoptosis by constraining Bcl-2 and elevating caspase-3 levels. GTN also attenuated the P13K/ AKT signaling which enhanced apoptosis. These findings revealed that GTN subdues the P13K/AKT pathway and has auspicious chemopreventive and apoptotic actions in DEN-induced HCC. Therefore, GTN would be suggested as a new medicine in natural remedies for liver cancer.

Multiple myeloma (MM) is a malignant tumor of the blood system that is more common in the elderly with abnormal proliferation of bone marrow plasma cells. The current diagnostic methods mainly rely on the detection of M protein and invasive bone marrow aspiration biopsy. The sensitivity and specificity of conventional imaging tests are low. Molecular imaging technology provides new options and methods for the noninvasive diagnosis of MM. Whole-body MRI (WB-MRI) has good soft tissue contrast and spatial resolution, which can show bone marrow infiltration and vascular conditions. Metabolic imaging such as 18F-FDG, acetate, choline, and methionine are highly sensitive. ImmunoPET imaging screens specific targets for targeted therapy or immunotherapy and evaluates the efficacy. This article reviews the progress of molecular imaging in MM, especially immunoPET imaging.

Objective:To investigate the molecular pathogenesis of two coagulation factor Ⅺ (FⅪ) deficiency patients.Methods:Coagulant assays: activated partial thromboplastin time(APTT), normal pooled-plasma corrected APTT test, PT, PT-INR and one-stage assay of coagulation factors activities were validated to diagnose coagulation factor Ⅺ deficiency. The patients’ DNA samples were extracted and all exons and flanking sequences of F11 gene were amplified using PCR. After purified, the products of PCR were sequenced directly, the mutations were detected by comparing with wild sequences and analyzed using some bio-informatics softwares. Results:The two patients were diagnosed with coagulation factor Ⅺ deficiency due to prolonged APTT, corrected APTT and low activities of coagulation factor FⅪ. The results of APTT, FⅪ∶C were 88.1s, 1.1% and 107.1s, 3.8% , and the prolonged APTT could be corrected to normal range 32.9s and 31.5s, respectively. Through genetic analysis, we discovered compound heterozygous mutations g. 1305-1G>A and g. 1325delT in patient 1 and the sequencing results of TA plasmid clones showed that the two mutations were located on different strands of chromosomes. Compound heterozygous mutations g. 1124A>G and g. 1550C>G were detected in patient 2 resulting in Lys357Arg and Cys482Trp. Software analysis indicated the mutations probably brought amino acid sequence changed, protein features affected and splice site changed.Conclusion:Compound heterozygous mutations g. 1305-1G>A, g. 1325delT and g. 1124A>G, g. 1550C>G had been identified in two coagulation factor Ⅺ deficiency patients which might be responsible for their prolonged APTT and low FⅪ∶C. To the best of our knowledge, g. 1325delT and g. 1550C>G have been reported, while g. 1124A>G and g. 1305-1G>A are reported for the first time in the literature.
