The importance of the P450 enzyme CYP1B1 in both cancer therapy and prevention are reviewed and evidence is discussed, which provides strong biological plausibility for the therapeutic merits of this approach. The significant resistance to chemotherapy among common cancers, and the realization that in many cases chemotherapy leaves behind drug-resistant cancer cells that eventually cause recurrence and metastatic disease, has recently prompted the search for natural compounds that would circumvent this problem...

BACKGROUND: Central nervous system (CNS) progression is common in patients with anaplastic lymphoma kinase-positive (ALK+) non-small-cell lung cancer (NSCLC) receiving crizotinib. Next-generation ALK inhibitors have shown activity against CNS metastases, but accurate assessment of response and progression is vital. Data from two phase II studies in crizotinib-refractory ALK+ NSCLC were pooled to examine the CNS efficacy of alectinib, a CNS-active ALK inhibitor, using Response Evaluation Criteria in Solid Tumours (RECIST version 1...

Zinc oxide nanostructure (ZnONS) was chemically synthesized and functionalized (FZnONSBLA) with a small protein bovine α-lactalbumin (BLA) by chemical cross-linking methods. Both nano-structures were characterized using various techniques such as electron microscopy, dynamic light scattering (DLS), UV-Vis spectroscopy, FT-IR, photo-luminescence and X-ray diffraction. Electron microscopy and DLS analysis revealed their (ZnONS and FZnONSBLA) average size of 200nm and 450nm, respectively. When cytotoxicity of both the nanostructures were assessed in breast cancer cells MCF-7 and MDAMB231 by MTT assay and PI/Annexin V staining (FACS), FZnONSBLA demonstrated higher cell death than ZnONS primarily due to generation of intracellular reactive oxygen species (ROS)...

It has been shown that Granulocyte colony-stimulating factor (G-CSF) has a higher expression in malignant tumors, and anti-G-CSF therapy considerably decreases tumor growth, tumor vascularization and metastasis. Thus, blocking the signaling pathway of G-CSF could be beneficial in cancer therapy. This study is aimed at designing and producing a monoclonal nanobody that could act as an antagonist of G-CSF receptor. Nanobodies are the antigen binding fragments of camelid single-chain antibodies, also known as VHH...

Polycystic ovary syndrome (PCOS) is the most prevalent endocrinopathy among women during reproductive age. PCOS is characterised by hyperandrogenaemia, hyperinsulinaemia, and deranged adipokines secretion from the adipose tissue. In addition to the reduced insulin sensitivity, PCOS women exhibit β-cell dysfunction as well. Low birth weight and foetal exposure to androgens may contribute to the development of the PCOS phenotype during life. Further metabolic complications lead to dyslipidaemia, worsening obesity and glucose tolerance, high prevalence of metabolic syndrome, and greater susceptibility to diabetes...

A series of "half-sandwich" Schiff-base Ir(III) complexes were synthesized and investigated for their in vitro activities against the leukemia K562 cell line. These compounds demonstrated antiproliferative activities against K562 cells with IC50 values of 0.26-4.77 μM. In particular, compound 10c showed cytotoxicity against five cancer cell lines/sublines and stronger activities than cisplatin in K562, K562/A02, MCF-7, MCF-7/ADM, and A549 cells. Mechanism studies illustrated that compound 10c increased the level of reactive oxygen species and induced apoptosis of K562 cells...

Cytology-based cervical cancer screening has led to substantial reductions in cancer incidence and mortality. Today, most cervical cancers arise in low-resource countries without screening. Since implementation of cytology is not feasible in most developing countries, visual screening and HPV testing are evaluated as alternative strategies. This article is protected by copyright.

Epithelial Mesenchymal Transition (EMT) plays key roles during lung development and many lung diseases such as Chronic Obstructive Pulmonary Disease (COPD), lung cancer and pulmonary fibrosis. Here, integrating morphological observations with underlying molecular mechanisms, we highlight the functional role of EMT in lung development and injury repair, and discuss how it can contribute to pathogenesis of chronic lung disease. We discuss the evidence of manifestation of EMT and its potential driving role in COPD, idiopathic pulmonary fibrosis (IPF), bronchiolitis obliterans syndrome (BOS), and lung cancer, while noting that all cells need not display a full EMT in any of these contexts, i...
