The papers covered a wide range of oncologic diseases: colon-rectal, gastric, breast cancer, ovarian, lung, all types of leukemia, prostate cancer, brain tumors etc; a wide range of cellular mechanisms: cell proliferation, cell migration, cell death, cell adhesion, cell counting, apoptose, phosphorylation, DNA damage, DNA ploidity, DNA sequencing, free circulating DNA etc. Samples used for the study were mainly plasma and tissue but saliva, feces, urine, exhaled breath concentrate etc were also reported for the study.
Regarding techniques, papers focused on: flow cytometry, tissue microarray, antibody microarray, reverse phase protein microarray, single nucleotide polymorphism; and also on mass spectrometry: MALDI-TOF-MS, SELDI-TOF-MS, liquid chromatography-tandem mass spectrometry (LC-MS/MS) etc.
The article emphasizes the need for standardization. With the emergence of omics fields, there are now no boundary between cellomics, genomics and proteomics. The genes codify processes and proteins as well as cells; as cells are under DNA control and are influenced through RNA protein synthesis, therefore the determination of proteins as the cells as well as the determination of DNA might be referred to as being genomic, proteomic or cellomic.
