Sample Submission Guidelines

You are encouraged to set up a meeting to consult for experimental design with the core director, Dr. Xiwei Wu, to determine the optimal platform, library preparation protocol, and sample size. Please fill out the service request form at the time of sample submission. Typical turnaround time for microarray service is one - two weeks, and three - four weeks for sequencing, one - four weeks for data analysis. Please note that actual turnaround time might vary depending on the work load and complexity of the project.
 
Sample Requirement for Microarray preparation
Quality check is required for all samples by the core using Agilent Bioanalyzer 2100, NanaDrop1000 or Qubit 2.0. Samples that fail the quality analysis will be returned to researcher and ask for replacement.
 
RNA Submissions
 
All RNA must be clean and free from protein and DNA contamination and meet the following minimum requirements:
 
260/280 ratios must be between 1.9 and 2.1
 
260/230 ratios must be above 1.8 (if < 1.8, samples has organic contaminants)
We recommend using the QIAGEN RNeasy columns for total RNA purification. When working with Qiagen RNeasy columns for use with the Affymetrix system, please do not use β-mercaptoethanol; it is unnecessary and can cause high background in your GeneChips.
 
For small RNA: Perform total RNA purification that retains the small RNA such as Qiagen miRNeasy Kit. Total RNA must be submitted, and please do not do the enrichment step. miRNA samples will require two quality control (QC) steps: one for total RNA and one for small RNA.
 
Usually, 500 ng -1 µg RNA is good enough for QC and sample preparation. But it is varied depending on the technologies of your choice. Please check with our core staff for specific requirement.
 
DNA Submissions

260/280 ratios must be between 1.8 and 2.0
 
260/230 ratios must be above 2.0 (if < 2, samples has organic contaminants)
Genomic DNA can be extracted using any method that generated high quality DNA.
Amplified DNA must be purified, and we recommend using the Qiagen QiaQuick PCR purification protocol with samples eluted in nuclease-free water or the elution buffer provided by in the kit.
 
1-2 µg DNA is required for success analysis. But it is varied depending on the technologies of your choice. Please check with our lab staff for specific requirement.

Abstract for Grant

The integrative genomics core (IGC) is a shared resource facility within the Beckman Research Institute (BRI) at City of Hope. Partially supported by NCI comprehensive cancer center grant, the goal of the IGC is to provide comprehensive genomic services from pre-experimental consultation, sample processing, data analysis and interpretation to manuscript and grant preparation.
 
The IGC is committed to providing these services in a cost-effective and timely manner to support basic science, translational, and clinical researchers at City of Hope.
 
The IGC is equipped with all major state-of-the-art microarray and sequencing platforms for genomic studies, including Illumina’s Hiseq 2500 and Life Technology’s Ion Proton sequencers, Illumina’s Hiscan Beadchip system, Affymetrix’s GeneChip system, and Agilent’s microarray system. 
 
The core also has a state-of-the-art Hitachi AB model 3730 48-capillary DNA Analyzer with the capacity to analyze 4,000 to 8,000 samples per week. These instruments enable a wide range of genetic, epigenetic and gene expression analysis capabilities, and complement each other for different applications, including transcriptomic and miRNA profiling, protein and DNA/RNA interaction, histone modifications, DNA methylation, SNP/indel, copy number variations and other structural variations, genome-wide and customer genotyping. The core also has an ABI Taqman Real-time PCR system, ViiA 7, an excellent technology for expression validation, as well as Nanodrop, Qubit 2.0 and Agilent Bioanalyzer for sample QC.
 
With a highly experienced team of bioinformaticians integrated within the core, efficient genomic data analysis services will be provided to convert high throughput data into biologically interpretable results. The team has established analysis pipelines for all major sequencing applications, e.g. RNA-seq, miRNA-seq, ChIP-seq, exome-seq, amplicon-seq, etc., and has extensive expertise in utilizing both commercial and open-source software tools for sequencing data analysis. These include but are not limited to R/Bioconductor, IGV, Bowtie, TopHat, Cufflinks, Novoalign, MACS, MEME, Transfac, BWA, GATK, Samtools, Gene Set Enrichment Analysis (GSEA), Ingenuity Pathway Analysis and DAVID.
 
The core processes over 1500 samples with microarray and sequencing instruments each year and supports bioinformatics analysis on all the data generated. The bioinformatics team is also experienced in mining public domain data, such as GEO, TCGA, and 1000 genome databases. The core also supports depositing the genomic data into NCBI’s GEO and SRA database for data sharing.

NEWS & UPDATES
  • Skin cancer is the most common type of cancer in the United States today, and its incidence is on the rise. Forty to 50 percent of light-skinned Americans who live to age 65 will have skin cancer at least once in their lives. Most of these skin cancers – about 3.5 million cases – are the […]
  • The connection between lifestyle and cancer is real. Knowing that, what can individuals do to lower their risk? City of Hope physicians recently came together to answer that precise question, explaining the links between cancer and the choices we make that affect our health. Moderator Vijay Trisal M.D., medical...
  • White button mushrooms seem fairly innocuous as fungi go. Unlike portabellas, they don’t center stage at the dinner table, and unlike truffles, they’re not the subject of gourmand fervor. But appearances can be deceiving when it comes to these mild-mannered Clark Kents of the food world. In a study ...
  • Doctors often recommend preventive screenings for several cancers, based on hereditary or genetic factors, but brain tumors aren’t one of them. Primary brain tumors, which originate in the brain rather than spreading from another location, seem to develop at random, and doctors have little insight into wh...
  • Stopping cancer starts with research. To that end, STOP CANCER has awarded $525,000 in grants to City of Hope for 2015, supporting innovative research projects and recognizing the institution’s leadership in advancing cancer treatment and prevention. Founded in 1988, STOP CANCER underwrites the work of le...
  • Cancer may not be the disease many people think it is. Normally, cancer is considered to be a disease in which cells multiply at an extremely high, and unusual, rate – increasing the likelihood of genetic mutations. But increasingly, leading researchers at City of Hope and elsewhere are contending that cancer i...
  • “Of all forms of inequality, injustice in the health care system is the most shocking and inhumane.” By the time the Rev. Martin Luther King Jr. spoke those words in Chicago in 1966, the Civil Rights Act had been passed, the Voting Rights Act was the law of the land and the March on Washington was […]
  • Eight years ago, Matthew Loscalzo surprised himself by accepting the offer to become City of Hope’s administrative director of the Sheri & Les Biller Patient and Family Resource Center and executive director of the Department of Supportive Care Medicine. At the time, he was administrative director of the Sc...
  • The mental fog that patients can experience after undergoing chemotherapy treatment for cancer has a name: “chemo brain.” “Many patients report hearing or reading about chemotherapy-related cognitive deficits, but few are actually prepared to deal with these changes,” said Celina Lemon, M.A., an occupational th...
  • Cancer treatments have improved over the years, but one potential source of treatments and cures remains largely untapped: nature. Blueberries, cinnamon, xinfeng, grape seed (and skin) extract, mushrooms, barberry and pomegranates all contain compounds with the potential to treat or prevent cancer. Scientists a...
  • In the U.S., there are more new cases of skin cancer than the combined incidence of cancers of the breast, prostate and lung, according to the American Cancer Society. Each year, 5 million people are treated for skin cancer. Here, Hans Schoellhammer, M.D., assistant clinical professor at City of Hope | Ant...
  • As public health experts know, health improvement starts in the community. Now, City of Hope  has been recognized for its efforts to improve the lives of residents of its own community. The institution will receive funding from the Institute for Healthcare Improvement  to support promising community-based work ...
  • For almost four decades, blood cancer survivors who received bone marrow, or stem cell, transplants have returned to City of Hope to celebrate life, second chances and science. The first reunion, in 1976, was a small affair: spaghetti for a single patient, his brother who served as his donor and those who took ...
  • Chemotherapy is an often-essential component of cancer treatment, attacking cells that divide quickly and helping stop cancer’s advance. But the very characteristics that make chemotherapy effective against cancer also can make it toxic to healthy cells, leading to side effects such as hair loss, nausea, ...
  • When you want to understand how to enhance the patient experience, go straight to the source: The patients. Patients and their families offer unique perspectives on care and services and can provide valuable insights about what is working well and what is not. That’s why City of Hope turns to them for advice. S...
