FGD1 exhibits oncogenic properties in hepatocellular carcinoma through regulating cell morphology, autophagy and mitochondrial function.

Faciogenital Dysplasia 1 (FGD1) has been involved in a variety of biological processes, including cytoskeleton restructuring, cell morphology, cell cycle progression, and cell polarity. Abnormal expression of FGD1 was also identified in several types of cancers, indicating its critical role in the development of cancers. However, little is known about the role of FGD1 in hepatocellular carcinoma (HCC).

TRAIP promotes malignant behaviors and correlates with poor prognosis in liver cancer.

TRAF-interacting protein (TRAIP) is a RING-type E3 ubiquitin ligase which has been implicated in various cellular processes, including NF-κB activation, DNA damage response, mitosis, and tumorigenesis. It is considered as a tumor suppressor in basal cell carcinomas and breast cancer in previous studies. However, in our current study, we found that TRAIP exhibited oncogenic properties in liver cancer.

Background: Hepatocellular carcinoma (HCC) is a common malignant gastrointestinal tumor. There are currently few clinical diagnostic and prognostic markers for HCC. LncRNA cancer susceptibility candidate 9 (CASC9) is a long-chain non-coding RNA discovered in recent years, and previous studies have found that lncRNA CASC9 participates in the occurrence and development of HCC, but its clinical value remains unclear.

Enterovirus type 71-immunized chicken egg yolk immunoglobulin has cross antiviral activity against coxsackievirus A16 .

To exploit a cross passive immunotherapy for enterovirus-induced hand-foot-and-mouth disease (HFMD), the cross antiviral activity of a neutralizing antibody against enterovirus 71 (EV71) and coxsackievirus A16 (CVA16) was investigated . White Leghorn specific-pathogen-free chickens were immunized with EV71 antigens and a specific isolated immunoglobulin (IgY) was prepared from the chicken egg yolk.
