Induction of Apoptosis and Chemosensitization by the Histone Deacetylase Inhibitor Trichostatin in Hepatocellular Carcinoma Cells: Molecular Analysis…

2011

The mRNA and protein levels of RKIP are reduced and those of YY1 increased in clinical HCC. Loss, mutation, or promoter hypermethylation of the RKIP gene may not account for the downregulation of RKIP in HCC. Histone deacetylation can silence gene expression and play a significant role in hepatocarcinogenesis. The histone deacetylase inhibitor (HDACI) trichostatin induced cell growth inhibition and proapoptotic effects in HA22T/VGH and HepG2 HCC cells; it also exhibited synergy with doxorubicin. Treatment with trichostatin caused histone hyperacetylation and down- or upregulated expression of different genes (such as β-catenin, cyclin D1, hTERT, XIAP, and IL-6). These changes might, at leas…

Subcutaneous C1 inhibitor for prevention of attacks of hereditary angioedema: additional outcomes and subgroup analysis of a placebo-controlled rando…

2019

Abstract Background Hereditary angioedema (HAE) is a debilitating disorder resulting from C1-esterase inhibitor (C1-INH) deficiency. In the COMPACT phase 3 study the prophylactic use of a subcutaneous C1 inhibitor (C1-INH [SC], HAEGARDA®, CSL Behring) twice weekly significantly reduced the frequency of acute edema attacks. Analysis of treatment effects by subgroups, onset of effect, and other exploratory analysis have not been reported. Methods This is a post hoc exploratory analysis on data from the randomized, placebo-controlled COMPACT study. 90 patients with C1-INH-HAE were randomized to 1 of 4 treatment sequences: C1-INH (SC) 40 or 60 IU/kg of body weight twice weekly for 16 weeks, pre…

The Interaction Mechanism of Intrinsically Disordered PP2A Inhibitor Proteins ARPP-16 and ARPP-19 With PP2A

2021

Protein phosphatase 2A (PP2A) activity is critical for maintaining normal physiological cellular functions. PP2A is inhibited by endogenous inhibitor proteins in several pathological conditions including cancer. A PP2A inhibitor protein, ARPP-19, has recently been connected to several human cancer types. Accordingly, the knowledge about ARPP-19—PP2A inhibition mechanism is crucial for the understanding the disease development and the therapeutic targeting of ARPP-19—PP2A. Here, we show the first structural characterization of ARPP-19, and its splice variant ARPP-16 using NMR spectroscopy, and SAXS. The results reveal that both ARPP proteins are intrinsically disordered but contain transient…

Human pasteurized C1-inhibitor concentrate for the treatment of hereditary angioedema due to C1-inhibitor deficiency.

2011

Hereditary angioedema is a relatively rare genetic disorder affecting between one in 10,000 and one in 50,000 individuals worldwide. The most common clinical symptoms observed are relapsing swelling of the skin and abdominal pain attacks. However, more serious and potentially fatal laryngeal attacks can also occur. Hereditary angioedema is most frequently caused by a deficiency of C1-inhibitor. Replacement therapy with Berinert, an intravenous pasteurized C1-inhibitor concentrate derived from human plasma, is a recommended treatment for rapid resolution of acute attacks of hereditary angioedema due to C1-inhibitor deficiency. Prophylactic therapy with C1-inhibitor is also available. Future …

Hereditary Angioedema: Increased Number of Attacks after Frequent Treatments with C1 Inhibitor Concentrate

2009

OBJECTIVE: C1 inhibitor concentrate is regarded as effective and safe in treating acute attacks of hereditary angioedema caused by C1 inhibitor deficiency. This study investigated the course of disease in 3 women treated frequently with C1 inhibitor concentrate. METHODS: Three women are described who received C1 inhibitor concentrate for the treatment of acute attacks of hereditary angioedema and experienced an increase in the frequency of attacks during that treatment period. In a control group of 24 patients aged more than 60 years with hereditary angioedema, the natural course of disease was determined. RESULTS: The 3 women (ages 50, 69, and 72 years) had received C1 inhibitor concentrat…

Hereditary angioedema: an update on causes, manifestations and treatment.

2019

Hereditary angioedema is a rare genetic disorder caused by deficiency of C1 esterase inhibitor (C1-INH) and characterized by recurrent episodes of severe swelling that affect the limbs, face, intestinal tract and airway. Since laryngeal oedema can be life-threatening as a result of asphyxiation, correct diagnosis and management of hereditary angioedema is vital. Hereditary angioedema attacks are mediated by bradykinin, the production of which is regulated by C1-INH. Hereditary angioedema therapy relies on treatment of acute attacks, and short- and long-term prophylaxis. Acute treatment options include C1-INH concentrate, icatibant and ecallantide. Self-administration of treatment is recomm…

Current status of implementation of self-administration training in various regions of Europe, Canada and the USA in the management of hereditary ang…

2013

Results from a 16-question survey about self-administration of hereditary angioedema (HAE) therapy, administered in Europe, Canada and the USA, were used to guide discussion at an international HAE expert meeting. The aim was to capture information about current practice in self-administered HAE therapy in these countries, including self-administration training, the key benefits of switching to self-administration, the barriers to self-administration and trends in self-administration. Overall, switching to self-administration therapy is looked upon favourably from both patient and clinician perspectives by virtue of the potential improvement in quality of life arising from optimisation of t…
