Kidney transplantation is the best treatment for end-stage renal failure. It prolongs the patient's life, improves quality of life and reduces costs associated with renal replacement therapy. Increasingly, newer immunosuppressive regimens allow for the proper functioning of the transplanted organ for many years. The progress in transplantation, qualification patients in older age for the procedure and longer survival of kidney graft lead to an increase in the number of patients receiving immunosuppressive drugs...

Melanoma is a most aggressive skin cancer with limited therapeutic options and its incidence is increasing rapidly in recent years. The discovery and application of new targeted therapy agents have shown significant benefits. However, adverse side-effects and resistance to chemotherapy remain formidable challenges in the clinical treatment of malignant melanoma. Nanotherapeutics offers an important prospect of overcoming these drawbacks. The anti-tumoral applications of nanomedicine are varied, including those in chemotherapy, RNA interference, photothermal therapy, and photodynamic therapy...

Rs1042522 (Arg72Pro) is a functional polymorphism of TP53. Pro72 has been associated with lower all-cause mortality and lower mortality after cancer. We hypothesized that TP53 Pro72 is associated with lower mortality after cancer, lower all-cause mortality, and with increased cancer incidence in the general population in a contemporary cohort. We genotyped 105,200 individuals aged 20-100 years from the Copenhagen General Population Study, recruited in 2003-2013, and followed them in Danish health registries...

Nivolumab, an anti-programmed death-1 antibody, is a breakthrough treatment for several malignancies. Its specific adverse effects caused by autoimmunity are termed immune-related adverse events, which involve several endocrine dysfunctions. Herein, we report two cases of isolated adrenocorticotropic hormone (ACTH) deficiency induced by nivolumab for the treatment of metastatic malignant melanoma. Case 1 was a 39-year-old man and Case 2 was a 50-year-old woman, both of whom presented with progressive melanoma...

Eryngium campestre and E. amethystinum are thorny herbs belonging to the Apiaceae family and spontaneously growing in stony pastures and dry meadows, preferentially on calcareous substrates. In the Mediterranean countries, these plants have been used as a food or traditional remedies to treat various ailments. In the present work, we have analysed the chemical composition of the essential oils distilled from the aerial parts by GC-FID and GC-MS, and evaluated their cytotoxic effects on a panel of human cancer cells, namely A375 (human malignant melanoma), MDA-MB 231 cells (human breast adenocarcinoma) and HCT116 cells (human colon carcinoma), by the MTT assay...

Laurence P Diggs, Eddy C Hsueh
We have seen a notable increase in the application of PD-1/PD-L1 inhibitors for the treatment of several solid and hematogenous malignancies including metastatic melanoma, non-small-cell lung cancer and lymphoma to name a few. The need for biomarkers for identification of a suitable patient population for this type of therapy is now pressing. While specific biomarker assays have been developed for these checkpoint inhibitors based on their respective epitopes, the available studies suggested the clinical utility of these biomarker assays is for response stratification and not patient selection...

Uveal melanoma (UM) is an intraocular malignant tumor with a high mortality rate. Recent studies have shown the functions of long non-coding RNAs (lncRNAs) in tumorigenesis; thus, targeting tumor-specific lncRNA abnormalities has become an attractive approach for developing therapeutics to treat uveal melanoma. In this study, we identified a novel nuclear CANT1 lncRNA (CASC15-New-Transcript 1) that acts as a necessary UM suppressor. CANT1 significantly reduced tumor metastatic capacity and tumor formation, either in cell culture or in animals harboring tumor xenograft...

BackgroundSkin cancer is the most common malignancy occurring after organ transplantation. Although previous research has reported an increased risk of skin cancer in solid organ transplant recipients (OTR), no study has estimated the post-transplant population-based incidence in the US. The objective of this study is to determine the incidence and evaluate the predictors of post-transplant skin cancer, including squamous cell carcinoma (SCC), melanoma (MM), and Merkel cell carcinoma (MCC) in a cohort of US OTR receiving a primary transplant in 2003 or 2008...

Cellular senescence is related to organismal aging and is observed after DNA damaging cancer therapies, that induce tumor-suppressive modifications, but it is characterized by a strong increase in secreted factors, termed the "senescence-associated secretory phenotype" (SASP). Particularly, SASP from stroma senescent fibroblasts creates a cancer-favoring microenvironment, providing targets for anti-cancer interventions. In the present article, chronic treatment (5 weeks) with 5 µM resveratrol has been used to modulate senescence-related protumoral features of MRC5 fibroblasts, reducing SASP-related interleukins IL1α, IL1β, IL6, and IL8; transforming-growth-factor-β (TGFβ); matrix metallo-proteinases MMP3 and MMP2; urokinase plasminogen activator (uPA); receptor proteins uPAR, IL6R, insulin growth factor receptor-1 (IGF-1R), TGFβ-R2, and CXCR4...

Deregulation of microRNAs (miRNAs) has been implicated in drug resistance in various types of cancers, including malignant melanoma (MM). MiR-488-3p has been reported as a tumor suppressor in several cancers. However, the exact expression patterns of miR-488-3p and the precise molecular mechanisms underlying its role in MM remain largely unknown and require further investigation. In this study, we demonstrated that miR-488-3p is significantly down regulated in MM clinical specimens and cell lines. Ectopic expression of miR-488-3p resulted in markedly increased drug sensitivity of MM cells in vitro and in vivo...
