Side population (SP) cells may play an important role in tumorigenesis and cancer therapy. We isolate and identify the cancer stem-like cells in human esophageal carcinoma (EC) cell lines, EC9706 and EC109 cells labeled with Hoechst 33342. Both the cell lines contained SP cells, and the cells that had the strongest dye efflux activity ("Tip"-SP cell) in(More)
Lung cancer (LC) with its different subtypes is generally known as a therapy resistant cancer with the highest morbidity rate worldwide. Therapy resistance of a tumor is thought to be related to cancer stem cells (CSCs) within the tumors. There have been indications that the lung cancer is propagated and maintained by a small population of CSCs. To study(More)
This paper focuses on an important research problem of Big Data classification in intrusion detection system. Deep Belief Networks is introduced to the field of intrusion detection, and an intrusion detection model based on Deep Belief Networks is proposed to apply in intrusion recognition domain. The deep hierarchical model is a deep neural network(More)
Recent reports have shown that cancer stem cells exist in many malignancies. Side population (SP) cells are used to enrich cancer stem-like cells in many cell lines and fresh tumor specimens. In this study, we cultured primary esophageal squamous cell carcinoma (ESCC) cells from ESCC tissue specimens. SP cells from primary ESCC cells were more resistant to(More)
Metastatic renal cell carcinoma (MRCC) is one of the malignancies that are sensitive to immunotherapy. However, the underlying immune inhibitory factors such as myeloid-derived suppressor cells (MDSCs) might restrain the efficacy of immunotherapy. The present study investigates the clinical efficacy of cytokine-induced killer (CIK) cell therapy in patients(More)
Side population (SP) cells may enrich stem-like cells in many normal and malignant tissues. However, SP method application has drawn special attention to the field of stem cell research, and the existence of SP cells in cell culture is being debated, most probably because different cell lines require different technical modifications, especially when cell(More)
BACKGROUND The aim of this study was to investigate the clinical efficacy of RetroNectin-activated cytokine-induced killer cell (R-CIK) therapy following conventional therapies in patients with metastatic brain tumors. METHODS This study included 20 patients with metastatic brain tumors. Patients received R-CIK therapy following conventional therapies(More)
Adoptive immunotherapy using cytokine-induced killer (CIK) cells is a promising cancer treatment, but its efficacy is restricted by various factors, including the accumulation of myeloid-derived suppressor cells (MDSCs). In this study, we determine whether chemotherapeutic drugs that reduce MDSC levels enhance the efficacy of CIK cell therapy in the(More)
BACKGROUND Advanced pancreatic cancer (PC) has very poor prognosis with present treatments, thus necessitating continued efforts to find improved therapeutic approaches. Both preclinical and preliminary clinical data indicate that cytokine-induced killer (CIK) cells are an effective tool against various types of solid tumors. Here, we conducted a study to(More)
T-cell exhaustion represents a progressive loss of T-cell function. The inhibitory receptor PD-1 is known to negatively regulate CD8+ T cell responses directed against tumor antigen, but the blockades of PD-1 pathway didn't show the objective responses in patients with colorectal cancer (CRC). Thus, further exploring the molecular mechanism responsible for(More)
