Bloom syndrome (BS) is an autosomal recessive inherited disorder characterized by chromosomal instability leading to a high risk of cancer at an early age. The diagnosis should be considered in patients with short stature, photosensitivity, variable degrees of immunodeficiency, and hypogonadism. We report a 19-year-old woman, with history of dysmorphic features and recurrent infections. The diagnosis of bloom syndrome was made and confirmed cytogenetically at the age of 14 years. She developed a colon cancer revealed by venous thrombosis and anemia. She died after 15 days of the cancer diagnosis. This is the first registrated case of confirmed Bloom syndrome in Tunisian population.

Experiments of nature have revealed the peculiar importance of the G-protein-coupled receptor, C-C chemokine receptor type 5 (CCR5), in human disease since ancient times. The resurgence of interest in heterotypic signals in the onset and progression of tumorigenesis has led to the current focus on CCR5 as an exciting new therapeutic target for metastatic cancer with clinical trials now targeting breast and colon cancer. The eutopic expression of CCR5 activates calcium signaling and thereby augments regulatory T cell (Treg) differentiation and migration to sites of inflammation. The misexpression of CCR5 in epithelial cells, induced upon oncogenic transformation, hijacks this migratory phenotype. CCR5 reexpression augments resistance to DNA-damaging agents and is sufficient to induce cancer metastasis and "stemness". Recent studies suggest important cross-talk between CCR5 signaling and immune checkpoint function. Because CCR5 on Tregs serves as the coreceptor for human immunodeficiency virus (HIV) entry, CCR5-targeted therapeutics used in HIV, [small molecules (maraviroc and vicriviroc) and a humanized mAb (leronlimab)], are now being repositioned in clinical trials as cancer therapeutics. As CCR5 is expressed on a broad array of tumors, the opportunity for therapeutic repositioning and the rationale for combination therapy approaches are reviewed herein.

Colorectal cancer (CRC) liver metastasis (CLM) is the leading death cause of CRC patients, but there is no satisfied approach to treat CLM. Gut microbiota plays a pivotal role in CRC initiation and development. Targeting dysbiosis of the gut microbiota might open up new opportunities for CLM treatment. Here, we investigated the efficacy of sodium butyrate (NaB), a major product of gut microbial fermentation, in modulating gut microbiota in CLM mice. NaB supplement decreased mouse colon cancer CT26 cell liver metastasis in intrasplenic tumor injection model of BALB/c mice. Using 16S rRNA gene sequencing, we found altered microbiota composition in CLM mice, characterized by increases of Firmicutes and Proteobacteria. NaB beneficially changed dysbiosis in CLM mice. Functional analysis of the KEGG pathways showed that NaB changed pathways related to immune system diseases and primary immunodeficiency in CLM mice. In addition, NaB decreased T regulatory cells and increased natural killer T cells and T helper 17 cells, accordingly decreased IL-10 and increased IL-17 secretion in CLM mice liver. In conclusion, NaB beneficially modulated gut microbiota and improved host immune response in CLM mice. These findings demonstrate the therapeutic potential of NaB in CLM treatment.

As a Traditional Chinese Medicine, Artemisia annua L. (A. annua) has been used for the treatment of various diseases since ancient times, including intermittent fevers due to malaria, bone steaming and heat/fever arising from exhaustion, tuberculosis, lice, wounds, scabies, dysentery et al. With the discovery of artemisinin and its excellent anti-malarial activity, A. annua has received great attention. Recently, A. annua has been revealed to show inhibitory effects against parasites (e.g. Plasmodium, Toxoplasma gondii, Leishmania, Acanthamoeba, Schistosoma), viruses (e.g. hepatitis A virus, herpes simplex viruses 1 and 2, human immunodeficiency virus), fungi (Candida, Malassezia, Saccharomyces spp.) and bacteria (Enterococcus, Streptococcus, Staphylococcus, Bacillus, Listeria, Haemophilus, Escherichia, Pseudomonas, Klebsiella, Acinetobacter, Salmonella, Yersinia spp.). A. annua has also been reported to possess anti-inflammatory and anti-cancer actions and been employed for the treatment of osteoarthritis, leukemia, colon cancer, renal cell carcinoma, breast cancer, non-small cell lung cancer, prostate cancre and hepatoma. Besides, the immunoregulation, anti-adipogenic, anti-ulcerogenic, anti-asthmatic, anti-nociceptive and anti-osteoporotic activities of A. annua were also evaluated. Along these lines, this review summarizes the traditional application and modern pharmacological research of A. annua, providing novel insights of A. annua in the treatment of various diseases.
