The present invention relates to prognostic methods which are useful in medicine, particularly cancer chemotherapy. The object of the invention to provide a method for assessing TS and/or ERCC1 expression levels in fixed or fixed and paraffin embedded tissues and prognosticate the probable resistance of a patient's tumor to treatment with 5-FU and oxaliplatin-based therapies by examination of the amount of TS and/or ERCC1 mRNA in a patient's tumor cells and comparing it to a predetermined threshold expression level for those genes. More specifically, the invention provides to oligonucleotide primer pairs ERCC1 and TS and methods comprising their use for detecting levels of ERCC1 and TS mRNA, respectively.

Method of determining a chemotherapeutic regimen based on ERCC1 and TS expression

There is disclosed an improved high-throughput and quantitative process for determining methylation patterns in genomic DNA samples based on amplifying modified nucleic acid, and detecting methylated nucleic acid based on amplification-dependent displacement of specifically annealed hybridization probes. Specifically, the inventive process provides for treating genomic DNA samples with sodium bisulfite to create methylation-dependent sequence differences, followed by detection with fluorescence-based quantitative PCR techniques. The process is particularly well suited for the rapid analysis of a large number of nucleic acid samples, such as those from collections of tumor tissues.

Process for high-throughput DNA methylation analysis

The invention relates to a method for determining a chemotherapeutic regimen for an individual, comprising obtaining a mRNA sample from a primary tumor specimen; determining a gene expression level for a tumor gene determinant in the specimen; comparing the gene expression level for the tumor gene determinant with a predetermined threshold value for that gene; and providing a chemotherapeutic regimen comprising a chemotherapeutic agent appropriate for the tumor gene determinant to treat the tumor metastases.

Method of determining a chemotherapeutic regimen by assaying gene expression in primary tumors

Methods are disclosed for rapid, reliable and simple isolation of RNA, DNA and proteins from formalin-fixed paraffin-embedded tissue samples. RNA purified in this manner can be used to monitor gene expression levels. The tissue sample can be a tumor or other pathological tissue.

Quantitative measurement of gene expression from fixed paraffin embedded tissue

Methods are disclosed for rapid, reliable and simple isolation of RNA from formalin-fixed paraffin-embedded tissue samples. RNA purified in this manner can be used for quantitative measurement gene expression levels. The tissue sample can be a tumor or other pathological tissue.

Process for high throughput DNA methylation analysis

The present invention relates to prognostic methods which are useful in medicine, particularly cancer chemotherapy. The object of the invention to provide a method for assessing GST-pi expression levels in fixed or fixed and paraffin embedded tissues and prognosticate the probable resistance or sensitivity of a patient's tumor to treatment with platinum-based therapies by examination of the amount of GST-pi mRNA in a patient's tumor cells and comparing it to a predetermined threshold expression level. More specifically, the invention provides to oligonucleotide primer pair GST-piand methods comprising their use for detecting levels of GST-pi mRNA.

The present invention relates to prognostic methods which are useful in medicine, particularly cancer chemotherapy. The object of the invention to provide a method for assessing ERCC1 expression levels in fixed or fixed and paraffin embedded tissues and determine a platinum-based chemotherapy by examination of the amount of ERCC1 mRNA in a patient's tumor cells and comparing it to a predetermined threshold expression level. More specifically, the invention provides to oligonucleotide primer pair ERCC1 and methods comprising their use for detecting levels of ERCC1 mRNA.

Method of determining a chemotherapeutic regimen based on ERCC1 expression

The present invention relates to prognostic methods which are useful in medicine, particularly cancer chemotherapy. The object of the invention to provide a method for assessing Dihydropyrimidine dehydrogenase (DPD) expression levels in tissues and prognosticate the probable resistance of a patient's tumor to treatment with 5-FU based therapies by examination of the amount of DPD mRNA in a patient's tumor cells and comparing it to a predetermined threshold expression level. More specifically, the invention provides to oligonucleotide primer pairs DPD3A and DPD3B and methods comprising their use for detecting levels of Dihydropyrimidine dehydrogenase (DPD) mRNA.
