Abstract

Objective: Metagenomics is a new science that revolutionized microbiology for its ability to study the microbiota
of a given environment without the need of culture. Human microbiota is the collection of microbes that inhabit
different sites of the human body and recently its alterations were related to different human diseases especially
cancers. Liver cancer incidence is continually increasing in Egypt with a high mortality rate. This study aimed to
identify the abundant microbial communities that inhabit the liver of the hepatocellular carcinoma patient and may be
associated with disease incidence or at least disease progression.
Methods: Fresh liver biopsy samples of two hepatocellular carcinoma Egyptian patients were obtained. DNA from
one sample and RNA from other sample were extracted followed by Illumina sequencing. Taxonomic and functional
analyses were performed using the MG-RAST server.
Results: Proteobacteria was the dominant phylum followed by Firmicutes and Actinobacteria in both DNA and
RNA samples. Some other phyla as Chlorobi, Bacteria and Cyanobacteria had the same abundance in the two
dataset. But it was noted that the bacterial diversity and presence of useful bacteria in sample 2 of grade 1 disease
(RNA sample) were more than it in sample 1 of grade 2 disease (DNA sample). Also, some other phyla are found in
the cDNA dataset annotations. On the other hand, infectious diseases pathways analysis showed the enrichment of
infectious diseases pathways of Staphylococcus aureus infection, Vibrio cholera infection, pathogenic Escherichia
coli infection, Hepatitis c, Tuberculosis, Epithelial cell signalling in Helicobacter pylori infection, Bacterial invasion of
epithelial cells, and salmonella infection.
Conclusions: There is a potential link between some definite microbial communities and liver cancer that need
some attention for improving early diagnosis and preventing disease progression. Further studies are required to
support this
