Special Issue Information

Dear Colleagues,

Colorectal cancer is one of the most widespread cancers in the world. Despite the many studies conducted in the field to date, a high rate of mortality and the development of anticancer treatments represent challenging battles.To date, a lot of information has been collected about the molecular mechanisms at the basis of the onset and progression of colorectal cancer, and many genes/proteins as well as regulating molecules have been linked to this tumor. Above all, in recent years NGS technologies have represented a key way by which immeasurable data have become obtainable, helping to better understand the cancer from a transcriptomic, genomic, metabolomic as well as metagenomic point of view, through a multi-omics approach.These data permit researchers to shed light and develop new diagnostic tools as well as therapeutical strategies against colorectal cancer.

This Special Issue aims to collect all the latest research and discoveries in this field in order to elucidate the molecular mechanisms underlying the development of colorectal cancer, exploring pharmaceutical and therapeutical applications to counteract it.  The original research or review papers are all welcome.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The progression of colorectal cancer is strongly influenced by environmental and genetic conditions. One of the key factors is tumor heterogeneity which is extensively studied by cfDNA and bulk sequencing methods; however, we lack knowledge regarding its effects at the single-cell level. Motivated by this, we aimed to employ an end-to-end single-cell sequencing workflow from tissue-derived sample isolation to exome sequencing. Our main goal was to investigate the heterogeneity patterns by laser microdissecting samples from different locations of a tissue slide. Moreover, by studying healthy colon control, tumor-associated normal, and colorectal cancer tissues, we explored tissue-specific heterogeneity motifs. For completeness, we also compared the performance of the whole-exome bulk, cfDNA, and single-cell sequencing methods based on variation at the level of a single nucleotide. Full article
