Recently, an increasing number of reports have indicated that a few patients who were believed to have recovered from COVID-19 initially tested negative but later tested positive. Several hospitals in different countries have detected SARS-CoV-2 RNA in the semen and cerebrospinal fluid of patients with severe COVID-19. Given the fact that the testes and central nervous system are both immune privilege sites and the fact that Ebola virus and Zika virus can avoid immune clearance and continue proliferating and spreading by hiding in those sites, the question of whether SARS-CoV-2 is present in immune privilege sites, it attacks those sites, and it spreads again after proliferating in those sites needs to be investigated.

Since the approval in 2017 and the amazing achievement of Kymriah and Yescarta, the number of basic researchers and clinical trials investigating the safety and efficacy of chimeric antigen receptor-expressing T cells (CAR-T cells) has been relentlessly increasing. Up to now, more than 200 clinical trials are listed on clinical trial database of NIH and the basic research is countless. However, the production of allogeneic CAR-T cells products is still expensive and has toxicity. Thus, more effort is needed to develop reliable off-the-shelf cellular therapeutic methods with safety and efficiency for the treatment of patients with cancer. As a kind of innate effector lymphocyte with potent antitumor activity, natural killer cells (NK cells) have attracted much attention. Until now, basic and clinical research has shown that chimeric antigen receptor-expressing NK cell (CAR-NK) therapy may play a significant anti-tumor role and its safety is higher than CAR-T cell therapy. In this review, we discuss advantages and shortages of employing CAR-NK cells as a novel cellular therapy against cancer.

Over the past few years, genetically modified organisms (GMO) have gradually become more familiar after numerous reports of problems with GMO safety, such as genetically modified (GM) potatoes disrupting immunity, GM corn inducing tumors, and GM rice being fed to unwitting Chinese children. Every time, these reports cause panic among the population and lead to objections to GMO in various fora. After each incident, the scientific community has delivered its academic appraisal and refuted rumors through slow and cautious investigations and evaluations. Unfortunately, during each event media outlets quickly scare the public about food safety and ignore the ensuing comments from scientists. Although scientists have investigated each GMO crisis and reached scientific and rational conclusions, they have less ability to disseminate information than the media, so the public is not promptly informed of their rational and objective viewpoints as experts. Thus, scientists need greater ability to disseminate information from scientific investigations and evaluations in order to correct the intemperate reporting by attention-seeking media.

Resveratrol (3, 5, 4'-trihydroxystilbene) is a phytoalexin contained in a variety of plants, such as grapes, berries and especially in the dried roots of Polygonum cuspidatum Sieb. et Zucc. It has been shown to exhibit anti-oxidative and anti-inflammation activity, and to reverse the effects of aging. Its ability to suppress cell proliferation, induce apoptosis and suppress the metastasis and invasion in a number of cell lines has prompted a large interest from people for its use as an anti-tumor component. In this review, evidence of resveratrol's anti-tumor effects and molecular mechanisms are recapitulated. First, we present the anti-apoptosis, anti-invasion/metastasis and anti-inflammation effect of resveratrol; second, the main signaling pathways involved in these activities are described and summarized with the studies of different tumors involved. Resveratrol not only induces apoptosis of tumor cells through intrinsic/extrinsic pathways and cell cycle arrest, but also inhibits the invasion and metastasis abilities of tumors via modulating collagen degradation-related molecular targets. Altogether, the present findings suggest the anti-tumor potential of resveratrol against various types of cancers.

ABSTRACT: Numerous studies have documented that in cancer therapy flavonoids extracted from traditional Chinese medicine have anti-tumor activity or can enhance efficiency of chemotherapy in combination with chemotherapeutics. Thus, an awareness of flavonoids is needed by physicians and medical researchers. This review provides evidence about anti-hepatocellular carcinoma activity of flavonoids. First, as a common employed in vitro model, profile of HepG2 is shown. Second, the intracellular signaling pathways induced by flavonoids which inhibit the HepG2 cell line are summarized. Third, study situation of anti-HBV/HCV activity of flavonoids is shown. Our review is aimed at providing an understanding of anti-HBV/HCV activity and anti-HCC mechanisms of flavonoids, and an outlook on flavonoids application on cancer therapy.
