Case report: Strategies for improving outcomes in patients with primary ovarian small-cell neuroendocrine carcinoma.

Small-cell neuroendocrine carcinoma (SCNEC) of the ovary is a gynecological malignancy characterized by rapid progression and poor prognosis. SCNEC is divided into primary and metastatic tumor. Primary ovarian neuroendocrine cancer is extremely rare and has a low 5-year survival rate. This paper reports the clinical manifestations of a 58-year-old patient with primary ovarian Small-cell neuroendocrine carcinoma and the prognosis after surgical adjuvant chemotherapy. The prevailing literature on this carcinoma is also reviewed and summarized. Our analysis reveals that histopathological examination is the standard diagnostic tool for ovarian SCNEC. We also highlight the importance of comprehensive imaging evaluation, early pathological diagnosis and comprehensive aggressive treatment to the prognosis of patients.

Focal adhesion kinase inhibitors, a heavy punch to cancer.

Kinases are the ideal druggable targets for diseases and especially were highlighted on cancer therapy. Focal adhesion kinase (FAK) is a non-receptor tyrosine kinase and its aberrant signaling extensively implicates in the progression of most cancer types, involving in cancer cell growth, adhesion, migration, and tumor microenvironment (TME) remodeling. FAK is commonly overexpressed and activated in a variety of cancers and plays as a targetable kinase in cancer therapy. FAK inhibitors already exhibited promising performance in preclinical and early-stage clinical trials. Moreover, substantial evidence has implied that targeting FAK is more effective in combination strategy, thereby reversing the failure of chemotherapies or targeted therapies in solid tumors. In the current review, we summarized the drug development progress, chemotherapy strategy, and perspective view for FAK inhibitors.

RNA virome screening in diverse but ecologically related citrus pests reveals potential virus-host interactions.

As an evergreen ecosystem, citrus orchards have specialized pest species and stable ecological homeostasis; thus, they provide an ideal model for investigating RNA viromes in diverse but ecologically related species. For this purpose, we collected specialized citrus pests from three classes of invertebrates, Insecta, Arachnida, and Gastropoda and we constructed two kinds of libraries (RNA and small RNA) for the pests by deep sequencing. In total, six virus-derived sequences were identified, including four Picornavirales, one Jingchuvirales and one Nidovirales. The picornavirus-derived small RNAs showed significant small RNA peaks and symmetric distribution patterns along the genome, which suggests these viruses infected the hosts and triggered host antiviral immunity RNA interference. Screening of virus-derived sequences in multiple species of citrus pests (n = 10 per species) showed that Eotetranychus kankitus picorna-like virus and Tetranychus urticae mivirus may be present in multiple pests. Our investigation in citrus pests confirmed that RNA viruses revealed by metagenomics could impact host immunity (e.g. RNAi). An approach with parallel deep sequencing of RNAs and small RNAs is useful not only for viral discoveries but also for understanding virus-host interactions of ecologically related but divergent pest species.
