Commensal bacteria are crucial to maintain immune homeostasis in mucosal tissues and disturbances in their ecology can affect disease susceptibility. Here, we report evidence that commensal bacteria shape the efficiency of immune surveillance in mucosal tissues. Antibiotic-treated (Abt) mice were more susceptible to development of engrafted B16/F10 melanoma(More)

Decidual lymphocytes may mediate fetal trophoblast recognition and regulate maternal immune reaction and play an essential role in the maintenance of normal pregnancy. The aim of this study was to compare the percentage of T cells, natural killer (NK) cells and natural killer T (NKT) cells within decidual parietalis of normal pregnant controls (NP) and(More)
Granulysin is a cytolytic, proinflammatory protein produced by human cytolytic T-lymphocytes and natural killer cells. Granulysin has two stable isoforms with molecular weight of 9 and 15 kDa; the 9-kDa form is a result of proteolytic maturation of the 15-kDa precursor. Recombinant 9-kDa granulysin exhibits cytolytic activity against a variety of microbes,(More)
BACKGROUND chA21 is a novel tumor-inhibitory antibody which recognized subdomain I of HER2 extracellular domain with an epitope distinct from other HER2 antibodies. Previously, we demonstrated that chA21 inhibits human ovarian carcinoma cell line SKOV-3 growth in vitro and in vivo study. In this study, we further investigated the anti-angiogenic efficacy(More)
Human epidermal growth factor receptor 2 (HER2) is one of the most studied tumor-associated antigens for cancer immunotherapy. An engineered anti-HER-2 chimeric A21 antibody (chA21) is a chimeric antibody targeted to subdomain I of the HER2 extracellular domain. Here, we report the anti-tumor activity of the novel engineered monoclonal antibody humanized(More)
OBJECTIVES The epithelial cell adhesion molecule (EpCAM) is one of the most commonly used markers of cancer stem cells (CSCs), but the clinical and prognostic significance of EpCAM in gastric cancer (GC) remains disputable. Motivated by heterogeneous and inconclusive results, we conducted a systematic review and meta-analysis to systematically summarize and(More)
A novel and efficient one-pot cascade synthesis of 2H-1,4-benzoxazin-3-(4H)-ones has been developed through copper-catalyzed coupling of o-halophenols and 2-halo-amides. Various 2H-1,4-benzoxazin-3-(4H)-ones with diversity at three substituents on their scaffold have been synthesized conveniently in good to excellent yields.
Pr ecis: These findings demonstrate the importance of commensal bacteria in supporting the host immune response against cancer in mucosal tissues and also suggest deleterious effects of antibiotic treatment on cancer susceptibility and progression. Pr ecis: This study offers a preclinical rationale for coadministering immune checkpoint therapies with cancer(More)
BACKGROUND MicroRNAs (miRNAs) was reported to be involved in cancer radio-resistance, which remains a major obstacle for effective cancer therapy. METHODS The differently expressed miRNAs were detected by RNA-seq experiment in nasopharyngeal cancer (NPC) cells. MiR-20a-5p was selected as our target, which was subject to finding its target gene Rab27B via(More)
