Gut microbiota plays a significant role in gout.

With the development of social economy, the incidence of gout is increasing, which is closely related to people's increasingly rich diet. Eating a diet high in purine, fat, sugar and low-fibre for a long time further aggravates gout by affecting uric acid metabolism. The renal metabolism mechanism of uric acid has been thoroughly studied.

Perspective view of allogeneic IgG tumor immunotherapy.

Allogeneic tumors are eradicated by host immunity; however, it is unknown how it is initiated until the report in Nature by Yaron Carmi et al. in 2015. Currently, we know that allogeneic tumors are eradicated by allogeneic IgG via dendritic cells.

Oncolytic virotherapy evolved into the fourth generation as tumor immunotherapy.

Background: Oncolytic virotherapy (OVT) is a promising anti-tumor modality that utilizes oncolytic viruses (OVs) to preferentially attack cancers rather than normal tissues. With the understanding particularly in the characteristics of viruses and tumor cells, numerous innovative OVs have been engineered to conquer cancers, such as Talimogene Laherparepvec (T-VEC) and tasadenoturev (DNX-2401). However, the therapeutic safety and efficacy must be further optimized and balanced to ensure the superior safe and efficient OVT in clinics, and reasonable combination therapy strategies are also important challenges worthy to be explored.

Nanoparticles advanced from preclinical studies to clinical trials for lung cancer therapy.

Lung cancer is the leading cause of cancer mortality. As a heterogeneous disease, it has different subtypes and various treatment modalities. In addition to conventional surgery, radiotherapy and chemotherapy, targeted therapy and immunotherapy have also been applied in the clinics.

Bispecific T cell engagers and their synergistic tumor immunotherapy with oncolytic viruses.

Tumor immunotherapy, especially T cell based therapy, is becoming the main force in clinical tumor therapies. Bispecific T cell engager (BiTE) uses the single chain variable fragments (scFv) of two antibodies to redirect T cells to kill target cells. BiTEs for hematologic tumors has been approved for clinical use, and BiTEs for solid tumors showed therapeutic effects in clinical trials.

Gut microbiota homeostasis restoration may become a novel therapy for breast cancer.

Breast cancer is the most diagnosed cancer in women. It significantly impairs a patient's physical and mental health. Gut microbiota comprise the bacteria residing in a host's gastrointestinal tract.

Oncolytic herpes simplex virus tumor targeting and neutralization escape by engineering viral envelope glycoproteins.

Oncolytic herpes simplex viruses (oHSVs) have been approved for clinical usage and become more and more popular for tumor virotherapy. However, there are still many issues for the oHSVs used in clinics and clinical trials. The main issues are the limited anti-tumor effects, intratumor injection, and some side effects.

Identification of Putative UL54 (ICP27) Transcription Regulatory Sequences Binding to Oct-1, v-Myb, Pax-6 and Hairy in Herpes Simplex Viruses.

An oncolytic herpes simplex virus (oHSV) has proven amenable in oncolytic virotherapy and was approved to treat melanoma. The immediate-early (IE) protein ICP27 encoded by gene UL54 is essential for HSV infection. Post-transcriptional modification of UL54 would increase tumor targeting of oHSVs.

Anticancer bioactive peptide (ACBP) inhibits gastric cancer cells by upregulating growth arrest and DNA damage-inducible gene 45A (GADD45A).

Recently, we reported that anticancer bioactive peptide (ACBP), purified from goat spleens immunized with human gastric cancer extracts, significantly inhibited gastric cancer cells in vitro and gastric tumors in vivo via repressing cell growth and promoting apoptosis, making it a promising potential biological anticancer drug. However, it is not known what genes are functionally required for the ACBP effects. Here, we first found that two tumor suppressor genes, cyclin-dependent kinase inhibitor 2B (CDKN2B) and growth arrest and DNA damage-inducible alpha (GADD45A), were upregulated significantly in the cells with ACBP treatment by microarray screening and the findings were validated by real-time RT-PCR.

Identification and characterization of a duck enteritis virus US3-like gene.

Duck enteritis virus (DEV) causes substantial losses on duck farms; however, its molecular biology is poorly understood. Here, an open reading frame of a US3-like gene of DEV was identified from a DEV genomic library. Its existence was confirmed by cloning from DEV-infected duck embryo fibroblasts (DEFs) and DNA sequencing.

Identification and characterization of the duck enteritis virus UL51 gene.

Compared to the UL51 gene of other alphaherpesviruses, the duck enteritis virus (DEV) UL51 gene contains ten conserved motifs and has a close evolutionary relationship with members of the genus Mardivirus. The DEV UL51 gene product was identified using a rabbit polyclonal antiserum raised against a 6-His-UL51 fusion protein expressed in Escherichia coli as a 34-kDa protein. Western blotting and RT-(real time) PCR analysis of DEV-infected cells showed that the protein was produced at the late stage of infection and that its production was highly dependent on viral DNA synthesis, suggesting that the gene should be classified as gamma2 class.
