Background: Since centuries plant-based compounds are known for the treatment of cancer in both traditional and contemporary medicine. The problems like target non-specificity and toxicity are well-known regarding anticancer drugs. Therefore, target specific search of novel entities is constant. Read More

Although emerging cell- or animal-based evidence supports the relationship between SND1 and cancers, no pan-cancer analysis is available. We thus first explored the potential oncogenic roles of SND1 across thirty-three tumors based on the datasets of TCGA (The cancer genome atlas) and GEO (Gene expression omnibus). SND1 is highly expressed in most cancers, and distinct associations exist between SND1 expression and prognosis of tumor patients. Read More

Metastases to the colon are rare and may mimic other diseases such as inflammatory bowel disease. This differential diagnosis is often overlooked by endoscopists which leads to unnecessary diagnostic delay or inappropriate treatment.

Recent studies have reported an increasing incidence of early onset colorectal cancer (CRC). Few studies compared the changing incidence of CRC by the major histological type, adenocarcinoma and neuroendocrine tumors (NETs). Using data from the Surveillance, Epidemiology, and End Results Program (SEER), we identified CRC from 1992 to 2015 with site and histological codes. Read More

Background: The main challenge in cancer research is the identification of different omic variables that present a prognostic value and personalised diagnosis for each tumour. The fact that the diagnosis is personalised opens the doors to the design and discovery of new specific treatments for each patient. In this context, this work offers new ways to reuse existing databases and work to create added value in research. Read More

Background: Complete mesocolic excision (CME) was first described in May 2009 by Werner Hohenberger and his colleagues (1). It arose from the concept of Total Mesorectal Excision illustrated by Heald (2), and consists of sharp dissection of the visceral fascial layer from the parietal one, complete mobilization of the mesocolon with an intact fascia and true central vascular ligation of the supplying arteries and draining veins at their origin. Current evidence suggests this technique is associated with better specimen quality, lower recurrence rates, higher disease-free survival, but also higher incidence of intraoperative injuries and surgical morbidity.

Recent retrospective studies of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) disease (COVID-19) revealed that the patients with common comorbidities of cancers and chronic diseases face significantly poorer clinical outcomes than those without. Since the expression profile of ACE2, a crucial cell entry receptor for SARS-CoV-2, could indicate the susceptibility to SARS-CoV-2 infection, here we systematically dissected ACE2 expression using large-scale multi-omics data from 30 organs/tissues, 33 cancer types and some common chronic diseases involving >28 000 samples. It was found that sex and age could be correlated with the susceptibility of SARS-CoV-2 infection for certain tissues. Read More

Utility of adjuvant chemotherapy for stage II cancer is still a matter of debate. Clinical guidelines suggest adjuvant chemotherapy for stage II tumors with high-risk features, in particular T4 tumors. However, limited consensus exists regarding the importance of other high risk features (lymphovascular or perineural invasion, microsatellite instability). Read More

Genome-wide association studies (GWAS) have led to the identification of hundreds of susceptibility loci across cancers, but the impact of further studies remains uncertain. Here we analyse summary-level data from GWAS of European ancestry across fourteen cancer sites to estimate the number of common susceptibility variants (polygenicity) and underlying effect-size distribution. All cancers show a high degree of polygenicity, involving at a minimum of thousands of loci. Read More

In advanced cancer, the RHOA GTPase is often active together with reduced expression of genes encoding Rho-specific GTPase-accelerating proteins (Rho-GAP), which negatively regulate RHOA and related GTPases. Here we used the TCGA dataset to examine 12 tumor types (including colon, breast, prostate, pancreas, lung adenocarcinoma and squamous cell carcinoma) for the frequency of codon mutations of 10 Rho-GAP and experimentally tested biochemical and biological consequences for cancer-associated mutants that arose in the DLC1 tumor suppressor gene. DLC1 was the Rho-GAP gene mutated most frequently, with 5-8% of tumors in five of the tumor types evaluated having DLC1 missense mutations. Read More

We present a technique to construct a simplification of a feature network which can be used for interactive data exploration, biological hypothesis generation, and the detection of communities or modules of cofunctional features. These are modules of features that are not necessarily correlated, but nevertheless exhibit common function in their network context as measured by similarity of relationships with neighboring features. In the case of genetic networks, traditional pathway analyses tend to assume that, ideally, all genes in a module exhibit very similar function, independent of relationships with other genes.

Background: Immune checkpoint inhibitors, the most widespread class of immunotherapies, have demonstrated unique response patterns that are not always adequately captured by traditional response criteria such as the Response Evaluation Criteria in Solid Tumors or even immune-specific response criteria. These response metrics rely on monitoring tumor growth, but an increase in tumor size and/or appearance after starting immunotherapy does not always represent tumor progression, but also can be a result of T cell infiltration and thus positive treatment response. Therefore, non-invasive and longitudinal monitoring of T cell infiltration are needed to assess the effects of immunotherapies such as checkpoint inhibitors. Read More

The data presented in this article is related with the research paper entitled "Evaluation of MGP gene expression in colorectal cancer", available on Gene journal [1]. From all the transcription factors known to regulate , FGF2 is the most described in colon adenocarcinoma and colon tumor cell lines, where it was shown to: i) contribute for the invasiveness potential; and ii) promote proliferation and survival of colorectal cancer cells. These studies pose the hypothesis that FGF2 associated signaling pathways could be promoting the regulation of others genes, such as that may lead to tumor progression which ultimately could result in poor prognosis in colon adenocarcinoma.
