Safflower seed extract synergizes the therapeutic effect of cisplatin and reduces cisplatin-induced nephrotoxicity in human colorectal carcinoma RKO cells and RKO-transplanted mice.

Safflower seed extract synergizes the therapeutic effect of cisplatin and reduces cisplatin-induced nephrotoxicity in human colorectal carcinoma RKO cells and RKO-transplanted mice. Drug Discov Ther. 2019;13(6):328-334 Authors: Park CH, Kim MJ, Yang CY, Yokozawa T, Shin YS Abstract Safflower seed is effective against oxidative stress, mediating the activation of the apoptotic signaling pathway in the renal tissues of cisplatin-treated mice. The anticancer activity of safflower in various cancer cell lines has also been reported. The present study was conducted to evaluate the potential synergistic anticancer effects of the co-treatment of safflower seed extracts and cisplatin in RKO cells and in BALB/c mice bearing RKO cell-derived human colorectal tumors. In the cellular system, RKO cells were treated with safflower seed extract in the presence or absence of cisplatin for 48 h and the cytotoxicity was evaluated by using microscopy. In the in vivo system, mice were injected with RKO cells and subsequently orally administered 100 or 200 mg/kg body weight safflower seed extract plus cisplatin-treated or untreated mice for 3 days to examine the inhibitory effect on the tumor. Treatment with safflower seed extract or cisplain to RKO cells resulted in a greater cell death than in with untreated cells. In the RKO cells co-treated with both safflower seed extract and cisplatin, greater cell damage was observed. In addition, mice co-administered safflower seed ex...

In conclusion, the patients with PTM had comparable outcomes with regard to mortality and cancer-specific mortality compared with those without PTM. This study showed that the patients with PTM can obtain an acceptable outcome after LDLT when carefully selected. PMID: 32023575 [PubMed - as supplied by publisher]

i H Abstract Cancer immunotherapy with immune checkpoint inhibitors (ICIs) such as programmed death ligand-1 (PD-L1) blockers offers pronounced clinical benefit with durable responses and a manageable safety profile. Patients with a high risk of immune-related adverse events are generally excluded from clinical trials testing ICI therapy. Thus, only a little information on the safety and clinical outcome of patients treated with an ICI after allogeneic haematopoietic cell transplantation (HCT) is currently available. Here, we report the characteristics and outcomes of six patients with, respectively, clear cell re...

In this study, we found that miR-452 was highly expressed in both tumor tissue and gastric cancer cells, and could directly target the cancer suppressor gene EPB41L3 3′-UTR. miR-452 significantly promoted the proliferation, migration and the S-phase arrest of gastric cancer cells, but EPB41L3 as a downstream target gene of miR-452 reversed such promoting effect. While down-regulation of miR-452 expression significantly inhibited the malignant biological behavior of gastric cancer cells, but this inhibitory effect was reversed by EPB41L3 siRNA. In addition, miR-452 in the gastric cancer xenograft model in nude mice co...

Discussion MDSCs violently emerge in pathological conditions in an attempt to limit potentially harmful immune and inflammatory responses. Mechanisms supporting their expansion and survival are deeply investigated in cancer, in the perspective to reactivate specific antitumor responses and prevent their contribution to disease evolution. These findings will likely contribute to improve the targeting of MDSCs in anticancer immunotherapies, either alone or in combination with immune checkpoint inhibitors. New evidence indicates that the expansion of myeloid cell differentiation in pathology is subject to fine-tuning, as its...

Conclusions Several model systems are now available to characterize the MSC-tumour interplay in the TME. These offer early promise in establishing robust preclinical platforms for the identification of crucial molecular pathways and for the assessment of clinical efficacy of novel drugs to inhibit cancer development and progression. However, selection of the right model for a given study should be shaped on the purpose, and should also consider fixed biological, biochemical, and biophysical parameters according to the specific tumour type. Finally, in order to get reliable and useful results to be translated to the clinic...

Conclusions and Perspectives It is interesting that watershed events, such as the loss of Neu5Gc from the glycocalyx of human cells have occurred numerous times in many mammalian and other vertebrate species. These cases of convergent evolution represent precious opportunities for increased understanding of evolutionary processes. In some respects, Neu5Gc is an ideal self-molecule as it is “private” to vertebrates and, based on current data, has yet to be successfully mimicked by microbes. Against the background of this benefit, the loss of Neu5Gc appears paradoxical and may implicate strong selective regimes,...

Conclusion and Perspectives The IL-6/JAK/STAT signaling cascade plays a dominant role in skeletal muscle pathophysiology. IL-6 autocrine, paracrine, and endocrine functions assign to its downstream effectors pivotal importance in skeletal muscle-wasting-associated diseases and other multiple system diseases where muscle acts in communication with other organs. Targeting the components of the JAK/STAT pathway recently emerged as a strategic approach for the treatment of inflammatory diseases and human cancer. This review highlights the opposite outcomes on muscle biology caused by the amount of local and systemic release ...
