Conjugated lactam-steroid alkylators (LSA), have been shown to exhibit superior activity at controlling cancer models and overlap drug resistance to conventional chemotherapy. Hybrid LSAs combine two active compounds in a single molecule and incorporate modified steroids bearing lactam moiety in one or more steroid rings functioning as vectors for cytotoxic agents. We first describe a novel class of LSAs that generate excellent anticancer activity against UWB1.289 and UWB1.289+BRCA1 human ovarian cancer cell lines...

Diagnosis and treatment of breast cancer is a very emotionally aversive and stressful life event, which can lead to impaired cognitive functioning and mental health. Breast cancer survivors responding with repressive emotion regulation strategies often show less adaptive coping and adverse outcomes. We investigated cognitive functioning and neural correlates of emotion processing using ERPs. Self-report measures of depression, anxiety, and fatigue, as well as hair cortisol as an index of chronic stress, were assessed...

Cancer is a leading cause of mortality in the world, with osteosarcoma being one of the most common types among children between 1 and 14 years old. Current treatments including preoperative chemotherapy, surgery and postoperative chemotherapy produce several side effects with limited effectiveness. The use of lipid nanoparticles as biodegradable shells for controlled drug delivery shows promise as a more effective and targeted tumor treatment. However, in vitro validation of these vehicles is limited due to fluid stagnation in current techniques, in which nanoparticles sediment onto the bottom of the wells killing the cells by asphyxiation...

BACKGROUND: In colon cancer, T4 stage is still assumed to be a relative contraindication for laparoscopic surgery considering the oncological safety. The aim of this systematic review with meta-analysis was to evaluate short- and long-term oncological outcomes after laparoscopic surgery for T4 colon cancer, and to compare these with open surgery. METHODS: Using systematic review of literature, studies reporting on radicality of resection, disease-free survival (DFS), and/or overall survival (OS) after laparoscopic surgery for T4 colon cancer were identified, with or without a control group of open surgery...

Ihn Han, Eun Ha Choi
Non-thermal atmospheric pressure plasma is ionized matter, composed of highly reactive species that include positive ions, negative ions, free radicals, neutral atoms, and molecules. Recent reports have suggested that non-thermal biocompatible plasma (NBP) can selectively kill a variety of cancer cells, and promote stem cell differentiation. However as of yet, the regulation of proliferation and differentiation potential of NBP has been poorly understood.Here, we investigated the effects of NBP on the osteogenic differentiation of precursor cell lines of osteoblasts, MC3T3 E1 and SaOS-2...

IL-35 is an immunosuppressive cytokine and exerts regulatory effects on T cells, B cells, macrophages and dendritic cells. Neutrophils are important innate immune cells that play key roles in tumor development. The effect of IL-35 on neutrophils remains unknown. Here, we report that IL-35 can induce N2 neutrophil polarization (protumor phenotype) by increasing G-CSF and IL-6 production, and promote neutrophil infiltration into tumor microenvironment. The sustained expression of IL-35 could promote chronic inflammation to augment the proangiogenic and immunosuppressive function of neutrophils...

The question of whether elevated blood glucose is a risk factor for liver cancer has been intensively studied, yet with inconsistent results. To explore the relationship between blood glucose concentration and risk of liver cancer, we conduct a meta-analysis of prospective studies. Literature search was comprehensively performed using database of PubMed, EMBASE and the Cochrane Library through October 2016. Random-effect models were used to combine the effect estimations. Eight articles containing ten studies with a total of 1975 liver cancer cases were included...

Personalized medicine is an important treatment approach for diseases like cancer with high intrasubject variability. In this framework, printing is one of the most promising methods since it permits dose and geometry adjustment of the final product. With this study, a combination product consisting of anticancer (paclitaxel) and antiviral (cidofovir) drugs was manufactured by inkjet printing onto adhesive film for local treatment of cervical cancers as a result of HPV infection. Furthermore, solubility problem of paclitaxel was overcome by maintaining this poorly soluble drug in a cyclodextrin inclusion complex and release of cidofovir was controlled by encapsulation in polycaprolactone nanoparticles...

BACKGROUND: In addition to being useful for classification, sequence variations of human Papillomavirus (HPV) genotypes have been implicated in differential oncogenic potential and a differential association with the different histological forms of invasive cervical cancer. These associations have also been indicated for HPV genotype lineages and sub-lineages. In order to better understand the potential implications of lineage variation in the occurrence of cervical cancers in Ghana, we studied the lineages of the three most prevalent HPV genotypes among women with normal cytology as baseline to further studies...

The drug research and development nowadays is focusing on multi-target drugs. In the treatment of cancer, therapies using drugs inhibiting one numerous targets signify a novel viewpoint. In comparison with traditional therapy, multi-targeted drugs directly aim cell subpopulations which are involved in progression of tumor. The current study comprises the synthesis of 34 novel ligustrazine-containing α, β-unsaturated carbonyl-based compounds and oximes. The growth of 5 various cancer cell types was strongly inhibited by ligustrazine-containing oximes as revealed by biological evaluation...

The extracellular signal-regulated kinase (ERK) is one of the most important molecular targets for cancer that controls diverse cellular processes such as proliferation, survival, differentiation and motility. Similarly, the Rb (retinoblastoma protein) is a tumor suppressor protein and its function is to prevent excessive cell growth by inhibiting cell cycle progression. When the cell is ready to divide, pRb is phosphorylated, becomes inactive and allows cell cycle progression. Herein, we discovered a new series of tetrahydrocarbazoles as dual inhibitors of pERK and pRb phosphorylation...

More than 3 million population residing in the holy city Varanasi and sub-urban areas is exposed to very high level of fine particulate matter (PM2.5) from various sources. Continuous monitoring by Central Pollution Control Board started only in 2015; therefore what was the pollution level in the past and how it has changed over the years are not known. We use MODIS aerosol products to infer PM2.5 and examine 15-year climatology. Data shows a rapid (1.5-3% per year) increase in PM2.5 in the last 15 years and high (87% days in a year) persistence of PM2...

Metastatic colon cancer is a major cause of deaths among colorectal cancer (CRC) patients. Elevated expression of kallikrein 6 (KLK6), a member of a kallikrein subfamily of peptidase S1 family serine proteases, has been reported in CRC and is associated with low patient survival rates and poor disease prognosis. We knocked down KLK6 expression in HCT116 colon cancer cells to determine the significance of KLK6 expression for metastatic dissemination and to identify the KLK6-associated microRNAs (miRNAs) signaling networks in metastatic colon cancer...
