  • Your Liver and Hepatitis B

    … amount of whole foods in your diet like fruits and vegetables while decreasing the amount of refined carbohydrates (pastas, white rice, white bread), processed sugar, and saturated fats which can create a healthy environment for your liver. Daily exercise: It is recommended for adults to exercise at least 60 minutes per day. Not only does this have many other health benefits, but it can reduce the fat surrounding your liver which can decrease your risk of liver cancer. Avoid the use of illicit drugs: Drugs like marijuana, cocaine, heroin, inhalants, or hallucinogens put stress on your liver and reduce its functioning capability. Wash produce and read labels on household chemicals: Pesticides and other chemicals can contain toxins which are harmful to your liver. Incorporating these healthy practices does not have to be difficult. Choose one of the five tips that is most convenient with your current lifestyle and use it as a starting point for a healthier routine. By gradually incorporating each healthy liver tip into your lifestyle, you can reduce your risk of a negative liver outcome creating a healthier you! Resources for Liver Cancer and Hepatitis B Please join Hepatitis B Foundation, Hep B United and Hep B United Philadelphia’s webinar on October 20th at 3PM ET to learn more about hepatitis B and liver cancer. Dr. Kenneth Rothestein, Director of Regional Outreach and Regional Hepatology from Penn Medicine will be highlighting the importance of liver cancer screening for prevention. Register here! To promote and ultimately prevent liver cancer this October we are pleased to share the Centers for Disease Control and Prevention’s Know Hepatitis B (KHB) Campaign Product of the Month – the Infographic: “Get Tested for Hepatitis B.” The CDC’s Know Hepatitis B Campaign’s infographic, “Get Tested for Hepatitis B” encourages Asian Americans and Pacific Islanders to get tested for hepatitis B.

    … here further elucidate the complex interactions of cell death effectors in the context of IAV infection. These findings may help in the development of novel IAV therapies as well as treatments for diseases with abnormally regulated cell death pathways. Meet our guest blogger, David Schad, B.Sc., Junior Research Fellow at the Baruch S. Blumberg Institute studying programmed cell death such as apoptosis and necroptosis in the context of hepatitis B infection under the direction of PI Dr. Roshan Thapa. David also mentors high school students from local area schools as part of an after-school program in the new teaching lab at the PA Biotech Center. His passion is learning, teaching and collaborating with others to conduct research to better understand nature.

    … virtual screen, ten compounds were further investigated, leading to the selection of one lead compound. This lead was further optimized for greater potency through chemical modifications resulting in the analogues CU-32 and CU-76. The IC50 of both compounds is below 1µM. To test these compounds' selectivity for cGAS, human monocyte cells THP-1 were either transfected with  interferon-stimulatory DNA (ISD) or infected with Sendai virus (SeV). ISD is a 45-basepair DNA known to activate cGAS, while SeV is a single-stranded RNA (ssRNA) virus known to activate the RIG-I-MAVS pathway; both stimuli are known to result in IRF3 activation and dimerization. Following treatment with both compounds, Western blot of the cells was conducted probing for the formation of IRF3 dimers. In ISD-treated cells, CU-32 and CU-76 inhibited the formation of IRF3 dimers in a dose responsive manner. Neither compound had any effect on IRF3 dimer formation in SeV-infected cells. This result indicates that these inhibitors are selective to cGAS. Using in silico molecular docking studies, the group speculates that these compounds disrupt the interface of the cGAS dimer, allosterically inhibiting dimerization. The discovery of novel cGAS inhibitors is exciting and important for multiple reasons. These compounds, if made commercially available will allow for improved experimentation investigating the cGAS/STING pathway. If these compounds or their derivatives are found to be safe and effective in humans, they may be promising candidates for the treatment of autoimmune disorders or cancer.   Meet our guest blogger, David Schad, B.Sc., Junior Research Fellow at the Baruch S.

    … of nucleic acids, but also as adjuvants that stimulate the STING pathway and activate tumor-infiltrating dendritic cells. This publication gives a glimpse into what future therapies for cancer may look like. The nanoparticle designed by this group is unique in that it has multiple functionalities: selectively targeting HCC cells, inhibiting PD-L1 expression, inducing IL-2 expression, and activating the STING pathway. Such a complex design is bound to require fine tuning before it can become a medicine. But a multi-target immunotherapeutic such as this may be exactly what is needed to help the body fight against aggressive, immunosupressive tumors. Lay Summary:  This month, the innate immune system was the focus of HBV research. Scientists hope to find how the innate immune system interacts with HBV during viral infection and proliferation. Doing so will shed light on host factors which lead to chronic infection and inform antiviral strategies. Notably, this month a human protein, MX2 was found to have potent anti-HBV activity by preventing cccDNA formation. Also, a microRNA encoded by HBV called HBV-miR-3 was found to activate the human innate immune system to limit HBV replication. This month, a paper studying woodchuck hepatitis virus (WHV) traked activation of the innate immune system as well as he adaptive immune system in an acute infection model. Also this month, concerning hepatocellular carcenoma (HCC), the alternative splicing of mRNA in tumors was found to vary in HCC patients based upon their risk factor (HBV, HCV, or alcohol). Finally, a review was published this month concerning STING, an innate immune protein which is not activated by HBV infection but which may prove a valuable tool for cancer treatment.   Meet our guest blogger, David Schad, B.Sc., Junior Research Fellow at the Baruch S.
