CD Genomics Perspective: NGS-Based Gene Panels for Cancer Research
IntroductionTumorigenesis involves in many somatic mutations, most of which are random. Generally, hundreds of genes are thought to be associated with oncogenesis progression and have high mutation rates. Digging deeper into the cancer genome can help to understand the molecular mechanisms of tumorigenesis and provide guidance for the prevention, treatment and prognosis strategies. The main ...

Evaluation of aberrant methylation gene tumour-risk forecasting value using attribute theory
We try to evaluate and forecast tumour risk using aberrant methylation genes as an index. We used the attribute theory to build up a database with the index of 50 aberrant methylation genes that relate to tumours, constructed a program to operate on the computer and obtained the result of tumour risk evaluation and forecasting. The programme can adjust the weight according to the qualitative ...

The histone demethylase kdm5b/jarid1b plays a role in cell fate decisions by blocking terminal differentiation
The histone demethylase lysine demethylase 5b (KDM5b) specifically demethylates lysine 4 of histone H3 (meH3K4), thereby repressing gene transcription. KDM5b regulates cell cycle control genes in cancer and is expressed in the early epiblast. This suggests that KDM5b plays a developmental role by maintaining uncommitted progenitors. Here we show that transient overexpression of KDM5b in embryonic ...

MRE11 and H2AX biomarkers in the response to low-dose exposure: balance between individual susceptibility to radiosensitivity and to genomic instability
Unrepaired and misrepaired DNA Double-Strand Breaks (DSBs) were shown to be the key events of radiation-induced toxicity (radiosensitivity) and genomic instability (cancer proneness), respectively. We have previously shown that immunofluorescence with ?-H2AX and MRE11 biomarkers may account for unrepaired and misrepaired DSBs for doses higher than 1 Gy. Three radiosensitivity groups had been ...

The development of complete personalized treatment plans for colon cancer patients utilizing three gene prediction models.
Background Combination chemotherapy using fluorouracil, leucovorin with or without oxaliplatin (5-FU and FOLFOX) are standard treatment for locally advanced colon cancer. However, about half of the patients developed recurrence. The objective of this study was to use gene profiling to predict treatment efficacy for colon cancer patients (stages 1-3). We developed three prediction models: the ...

Poly(propyleneimine) dendrimers as potential siRNA delivery nanocarrier: from structure to function
The goal of the present investigation is to reveal the role of the Poly(propyleneimine) (PPI) dendrimer structure on the siRNA nanoparticles formation, facilitation of cell internalisation, and sequence specific knockdown of targeted genes. It was found that the higher generations of PPI dendrimers (G4 and G5) most effectively initiated the complexation of siRNA into discrete nanoparticles when ...

Detection of biomarker p53 mutated gene by a silicon nanowire nanosensor
Among biosensors of various types, the silicon nanowire field–effect transistor (SiNW–FET) is believed to be the most sensitive and powerful device for bio–applications. In fact, these devices have demonstrated the ability to detect a variety of analyses such as particular DNA sequences, cancer biomarkers and larger entities such as viruses. The principle of sensing is based on the variation of ...

Carbon nanotube-based electrochemical signal amplification for breast cancer gene detection
Carbon-nanotubes (CNT) represent an important group of nanomaterials with useful properties that enable their use for many important applications and made them extremely attractive for the task of electrochemical detection. Here, the author uses CNT to enhance the sensitivity of a multi-enzyme-based electrochemical bioassay for breast cancer gene (BRCA1) detection. Giant enzyme-based ...

Methylation Markers of Pancreatic Cancer categorization and prognosis evaluation
Background Pancreatic cancer is one of the highest mortality rate cancers worldwide with 5-year relative survival of 10.8%. Lack of screening methods for early-stage detection as well as proper patient sub-characterization, make it a fatal cancer due to poor diagnoses and insufficient treatment. Methylation flags are kept on tumorigenesis, akin to the tissue-specific traces that are acquired and ...

CD Genomics Perspective: The Application of RNA-Seq and DNA-Seq in Cancer Research
Clinicians can make better diagnostic and treatment decisions using the data obtained by next-generation sequencing (NGS) technologies. Breast cancers, for example, have typically been diagnosed using mammography, physical exam, and histology. Genetics became more significant after the discoveries of oncogenes and other biomarkers. Today, commercially available microarray-based tests enable more ...

Applications of nanotechnology in drug delivery systems for the treatment of cancer and diabetes
This paper discusses potential applications of nanotechnology in drug delivery systems and pharmacotherapeutics. There are a few limitations in the use of conventionally available drug delivery systems as pharmacological agents in disease treatment. Lack of target specificity, altered effects and diminished potency due to drug metabolism in the body, cytotoxicity of certain anti-carcinogenic ...

Epigenomics: Opening the Black Box of Cancer
The epigenome is composed of chemical markers and proteins that can attach to DNA and direct the function of gene regulatory elements, controlling the production of proteins in specific cells, among other roles. Common epigenomic modifications include methylation of the nucleotide cytosine and histones or acetylation and phosphorylation of histones. All of these modifications do not change the ...

Comparison of genomic signatures of non-small cell lung cancer recurrence between two microarray platforms
Abstract Background Cancer genomic signatures may vary using different platforms. We compared the differential gene expression in non-small cell lung cancer (NSCLC) between two platforms in order to find the most relevant genomic signatures of tumor recurrence. Materials and Methods We analyzed gene expression in frozen lung cancer tissue from 59 selected patients who had undergone surgical ...

Regulation of cancer by therapeutic vaccination and dietary bio-modulation involving organ-specific mitochondria
Cancer therapy should aim to prevent recurrent disease. Surgery and toxic treatments remove only symptoms associated with cancer without trying to intervene in the aetiology, therefore the disease may recur. The autologous cancer vaccine supplemented with bio-modulation might fulfil requirements for effective tumour therapy. The autologous tumour vaccine is formed in the same way as our bodily ...
