Tumor heterogeneity is a major challenge when it comes to treating cancer and also complicates research aimed at determining genetic sources for tumorigenesis. Leveraging high-throughput sequencing technology has been an effective approach for advancing our understanding of genetic diseases, and this type of data can also be used to better understand and make inferences about tumor heterogeneity. Here we describe the basics of genomics data analysis, as well as analysis pipelines for investigating tumor heterogeneity with next-generation sequencing data...

PURPOSE: Preexisting diabetes is associated with increased morbidity and mortality in cancer. We examined the impact of incident cancer on the long-term outcomes of diabetes. METHODS: Using the United Kingdom Clinical Practice Research Datalink, we identified three cohorts of diabetes patients subsequently diagnosed with breast, colorectal, or prostate cancer, each matched to diabetic noncancer controls. Patients were required to have survived at least 1 year after cancer diagnosis (cases) or a matched index date (controls), and were followed up to 10 years for incident microvascular and macrovascular complications and mortality...

Cancer is a multi-stage process resulting from aberrant signaling pathways driving uncontrolled proliferation of transformed cells. The development and progression of cancer from a premalignant lesion towards a metastatic tumor requires accumulation of mutations in many regulatory genes of the cell. Different chemopreventative approaches have been sought to interfere with initiation and control malignant progression. Here we present research on dietary compounds with evidence of cancer prevention activity that highlights the potential beneficial effect of a diet rich in cruciferous vegetables...

In this research poly(l-lysine)-b-poly(l-leucine) (PLys-b-PLeu) polymersomes were developed. It was shown that the size of nanoparticles depended on pH of self-assembly process and varied from 180 to 650nm. The biodegradation of PLys-b-PLeu nanoparticles was evaluated using in vitro polypeptide hydrolysis in two model enzymatic systems, as well as in human blood plasma. The experiments of the visualization of cellular uptake of rhodamine 6g-loaded and fluorescein-labeled nanoparticles were carried out, which approved the possibility of their penetration into the cells...

From the first identification of aberrant DNA methylation in primary human tumors more than three decades ago, exponential progress in cancer epigenetics research has been made. For many years, cancer epigenetics studies relied on identification of DNA methylation and histone modifications at specific genes. These studies laid the foundation for the field and revealed the epigenetic alterations as hallmark of cancer, as well as the crucial role of epigenetic mechanisms in tumorigenesis. The introduction of next-generation sequencing and array-based technologies for analyzing epigenetic states has accelerated our understanding about cancer and nowadays have become potent tools in our fight against the disease...

RNA sequencing (RNA-Seq) and microarray are two of the most commonly used high-throughput technologies for transcriptome profiling; however, they both have their own inherent strengths and limitations. This research aims to analyze the correlation between microarrays and RNA-Seq detection of transcripts in the same tissue sample to explore the reproducibility between the techniques. Using data of RNA-Seq v2 and three different microarrays provided by The Cancer Genome Atlas, 11,120 genes of 111 lung squamous cell carcinoma samples were simultaneously detected by the four methods...

Dynamic properties of cancer cells, most notably their ability to migrate, have been correlated successfully with their invasive nature in vivo. To establish a stronger experimental basis for such a correlation we subjected five different cancer cell lines of well-defined metastatic potential to a sequence of three independent assays reporting on three different aspects of cell dynamics, namely (1) the kinetics of cell spreading, (2) cell shape fluctuations, and (3) cell migration. The sequentially applied assays correspond to different measuring modes of the well-established ECIS technique that is based on non-invasive and label-free impedance readings of planar gold-film electrodes that serve as the growth substrate for the cells under study...

INTRODUCTION: Primary small cell neuroendocrine carcinoma of the breast (SCNCB) is a very uncommon type of breast cancer. Histology and morphology are virtually indistinguishable from small cell neuroendocrine carcinomas of the lung (SCNCL), mandating a search for a primary site elsewhere in the body. There is no standard approach to treatment as there are only a limited number of cases reported in the literature. This report summarizes a case of primary SCNCB and presents a review of the literature...

MiR-21, the only miRNA found to be overexpressed in any type of solid tumor, its guide stand, miR-21-5p, has been studied a lot in colorectal cancer (CRC), however, few researchers focused on its passenger strand, miR-21-3p. In this study, based on The Cancer Genome Atlas (TCGA) data, we found that there were more variety and quantity of miR-21-3p isoforms in microsatellite instability (MSI)-type CRC. We further examined the role of miR-21-3p by in vitro and in vivo studies. MiR-21-3p may be an oncogene in CRC by promoting cellular mobility through epithelial-mesenchymal transition (EMT)...

The potential use of organometallic ruthenium complexes as anticancer drugs is well known. Here we show a family of activatable tethered ruthenium(II) arene complexes of general formula [Ru(η⁶:κ¹-C₆H₅(C₆H₄)NH₂)(XY)]n+ (closed tether-ring) bearing different chelating XY ligands (XY = aliphatic diamine, phenylenediamine, oxalato, bis(phosphino)ethane). The activation of these complexes (closed-to-open tether conversion) occurs in methanol and dimethylsulfoxide at different rates, and to different reaction extents at equilibrium...

Oxygen and Indocyanine Green (ICG) loaded microparticles (OI-MPs) were fabricated by a gas-driven coaxial flow focusing (CFF) process for dual-mode imaging and sonodynamic therapy (SDT). The produced OI-MPs agent showed stable optical properties, superior imaging depth in near infrared (NIR) fluorescence imaging, and enhanced acoustic contrast after ultrasound mediation. We hypothesized that encapsulating ICG and oxygen in microparticles would enhance reactive oxygen species (ROS) production in SDT. This hypothesis was validated in a cell-free environment...

Silibinin (silybin), a non-toxic natural polyphenolic flavonoid, is the principal and the most biologically active component of silymarin. It is efficient in the treatment of acute and chronic liver disorders caused by toxins, drug, alcohol, hepatitis, and gall bladder disorders. Further, in our previous studies, we explored the anti-cancer efficacy in common cancers, such as lung, prostatic, colon, breast, bladder, as well as, hepatocellular carcinoma. Interestingly, silibinin is still not solely limited to the treatment of these diseases...

Chengcheng Zhang, Zhongqi Wang, Qing Ji, Qi Li
Histone methylation is one of the major epigenetic modifications, and various histone methylases and demethylases participate in the epigenetic regulating. JMJD2C has been recently identified as one of the histone lysine demethylases. As one member of the Jumonji-C histone demethylase family, JMJD2C has the ability to demethylate tri- or di-methylated histone 3 and 2 in either K9 (lysine residue 9) or K36 (lysine residue 36) sites by an oxidative reaction, thereby affecting heterochromatin formation, genomic imprinting, X-chromosome inactivation, and transcriptional regulation of genes...

BACKGROUND: Premenopausal women undergoing chemotherapy are at high risk for premature ovarian failure and its long-term consequences. Data on potential markers to evaluate ovarian reserve pre- and posttreatment are limited. Anti-Müllerian hormone (AMH) known for ovarian reserve in reproductive medicine could be a surrogate marker and was assessed in premenopausal breast cancer patients of the SUCCESS A study (EUDRA-CT no. 2005-000490-21). METHODS: We identified 170 premenopausal patients, age ≤ 40 years at trial entry, who received FEC-Doc as taxane-anthracylince based chemotherapy...

Genomics data from The Cancer Genome Atlas (TCGA) project has led to the comprehensive molecular characterization of multiple cancer types. The large sample numbers in TCGA offer an excellent opportunity to address questions associated with tumo heterogeneity. Exploration of the data by cancer researchers and clinicians is imperative to unearth novel therapeutic/diagnostic biomarkers. Various computational tools have been developed to aid researchers in carrying out specific TCGA data analyses; however there is need for resources to facilitate the study of gene expression variations and survival associations across tumors...
