Finally, significant increases in the self-renewal ability, intracellular radical oxygen species levels and mitochondrial mass were detected in the CD133+ /CD44+ subpopulations isolated from CRC cells regardless of their LRH-1 expression levels. Together, our results suggest a novel metabolic symbiosis between different colorectal cancer stem cell subpopulations critical for maintaining their mutual stemness. © 2020 The Authors.

This body color asymmetry develops by restricted differentiation of melanophores and xanthophores on the ocular-side during metamorphosis, accompanied by migration of one eye to the future ocular-side. In this study, we elucidated the developmental regulatory system of this lateralized pigmentation. We found that in flounder, Sox10-positive chromatophore progenitors appear bilaterally both in the ocular- and blind-side skin of metamorphosing larvae, and that those arriving at the ocular-side skin differentiate into gch2-positive chromatoblasts and then chromatophores. Transient exposure of metamorphosing larvae to retinoic acid (RA)-induced progenitors on the blind-side to differentiate into gch2-positive chromatoblasts. On the contrary, exposure to an RA receptor antagonist, BMS493, suppressed the differentiation of gch2-positive chromatoblasts on the ocular-side. Thus, we demonstrated that RA is essential for flounder chromatophore progenitors to differentiate into chromatoblasts. At the time of chromatoblast differentiation on the ocular-side, cyp26b1, which inactivates RA, was upregulated on the blind-side skin compared with the ocular-side. Therefore, we surmise that ocular-side-specific pigmentation is regulated by the inhibition of RA-signaling by cyp26b1 on the blind-side. © 2020 Wiley-Liss, Inc., A Wiley Company.BACKGROUND Early intervention for psychosis is recommended because the first 5 years beyond the first episode is considered the critical period within which individuals have the most potential to maximize their response to treatment and recovery. Mindfulness-based interventions (MBIs) have been studied extensively in diverse disease groups, but research in people with recent-onset psychosis is still immature. AIM This review aims to explore the feasibility, acceptability and summarize any effectiveness data on of the MBIs for people with recent-onset psychosis reported by the study authors. METHODS A systematic search of original intervention research studies relevant to the topic published between January 2000 and August 2019 was conducted with 10 databases. Articles published in English with accessible full text were included. RESULTS A total of eight studies were included, which reported recruitment rates of between 62.5% and 100%, withdrawal rates between 0% and 37.5% and attendance rates of between 56% and 100%. Participants' qualitative feedback indicated high levels of satisfaction with the MBIs. The intervention approaches adopted in the reviewed studies include mindfulness-based interventions, acceptance and commitment therapy and compassion-based interventions. MBIs have produced promising positive effects on participants' psychiatric and psychosocial outcomes. CONCLUSION This review confirms that MBIs are generally feasible and acceptable for people with recent-onset psychosis. The preliminary results suggested the potential effects of MBIs in this area. Fully powered randomized controlled trials are suggested to confirm the effectiveness and exploratory studies to gain greater insight into the active components and mechanism of actions of MBIs for recent-onset psychosis. © 2020 John Wiley & Sons Australia, Ltd.Platinum-based compounds remain a well-established chemotherapy for cancer treatment despite their adverse effects which substantially restrict the therapeutic windows of the drugs. Both the cell type-specific toxicity and the clinical responsiveness of tumors have been associated with mechanisms that alter drug entry and export. We sought to identify pharmacological agents that promote cisplatin (CP) efficacy by augmenting the levels of drug-induced DNA lesions in malignant cells and simultaneously protecting normal tissues from accumulating such damage and from functional loss. Formation and persistence of platination products in the DNA of individual nuclei were measured in drug-exposed cell lines, in primary human tumor cells and in tissue sections using an immunocytochemical method. Using a mouse model of CP-induced toxicity, the antihistaminic drug diphenhydramine (DIPH) and two methylated derivatives decreased DNA platination in normal tissues and also ameliorated nephrotoxicity, ototoxicity, and neurotoxicity. TAPI-1 solubility dmso In addition, DIPH sensitized multiple cancer cell types, particularly ovarian cancer cells, to CP by increasing intracellular uptake, DNA platination, and/or apoptosis in cell lines and in patient-derived primary tumor cells. Mechanistically, DIPH diminished transport capacity of CP efflux pumps MRP2, MRP3, and MRP5 particularly in its C2+C6 bimethylated form. Overall, we demonstrate that DIPH reduces side effects of platinum-based chemotherapy and simultaneously inhibits key mechanisms of platinum resistance. We propose that measuring DNA platination after ex vivo exposure may predict the responsiveness of individual tumors to DIPH-like modulators. © 2020 The Authors.

Dynamic reciprocity between the cell and its associated matrix is essential to the maintenance of tissue homeostasis and dysregulation of both ECM mechanical signaling, via pathological ECM turnover, and internal mechanotransduction pathways contribute to disease progression. This review covers the current understandings of the key modes of signaling used by both the cell and ECM to coregulate one another. By taking an outside-in approach, the inherent complexities and regulatory processes at each level of signaling (ECM, plasma membrane, focal adhesion, and cytoplasm) are captured to give a comprehensive picture of the internal and external mechanoregulatory environment. Specific emphasis is placed on the focal adhesion complex which acts as a central hub of mechanical signaling, regulating cell spreading, migration, proliferation, and differentiation.
