    Abstract Targeted therapeutic options and prognostic biomarkers for hormone receptor- or Her2 receptor-negative breast cancers are severely limited. The sigma-1 receptor, a stress-activated chaperone, is frequently dysregulated in disease. However, its significance in breast cancer (BCa) has not been adequately explored. Here, we report that the sigma-1 receptor gene (SIGMAR1) is elevated in BCa, particularly in the aggressive triple-negative (TNBC) subtype. By examining several patient datasets, we found that high expression at both the gene (SIGMAR1) and protein (Sig1R) levels associated with poor survival outcomes, specifically in ER-Her2- groups. Our data further show that high SIGMAR1 was predictive of shorter survival times in patients treated with adjuvant chemotherapy (ChT). Interestingly, in a separate cohort who received neoadjuvant taxane + anthracycline treatment, elevated SIGMAR1 associated with higher rates of pathologic complete response (pCR). Treatment with a Sig1R antagonist, 1-(4-iodophenyl)-3-(2-adamantyl)guanidine (IPAG), activated the unfolded protein response (UPR) in TNBC (high-Sig1R expressing) and ER + (low-Sig1R expressing) BCa cell lines. In tamoxifen-resistant LY2 cells, IPAG caused Sig1R to aggregate and co-localise with the stress marker BiP. These findings showcase the potential of Sig1R as a novel biomarker in TNBC as well as highlight its ligand-induced interference with the stress-coping mechanisms of BCa cells.

    Abstract Mycochemical properties and bioactivities of Ganoderma resinaceum and Serpula similis remain unexplored. The present study assessed antioxidant, cytotoxicity, and cell migration abilities of Ganoderma and Serpula extracts, followed by their phytochemical analyses. The MTT assay was conducted to determine the cytotoxicity along with the cell migration studies in human cancer cell lines. The antioxidant profiles were evaluated through DPPH and FRAP assays. Furthermore, LC-MS/MS analysis was performed to elucidate the phytochemicals responsible for anticancer and antioxidant activities. Significant concentration-dependent cytotoxicities of 12.7% and 13.7% were observed against HCT 116 cell lines at 1% and 5% concentrations of the G. resinaceum extract, respectively. Similarly, significant concentration-dependent cytotoxicities of 6.7% and 25.5% were observed at 1% and 5% concentrations of the S. similis extract, respectively. The extracts of G. resinaceum and S. similis both shows better anti-migration potential in lung cancer cells. Both extracts demonstrated good scavenging activity on DPPH and ferric ion free radicals. LC-MS analysis revealed 11 compounds from S. similis and 15 compounds from G. resinaceum fruiting bodies. Compounds such as terpenoids, alkaloids, cytotoxic peptides, and other metabolites were identified as major components in both extracts. These extracts exhibited cytotoxic activity against HCT 116 cancer cells, along with moderate antioxidant activity. This implies that the extracts might be used as bioactive natural sources in the pharmaceutical and food industries.

    Abstract Background: Communities living in developing countries as well as populations affected by natural or man-made disasters can be left at great risk from water related diseases, especially those spread through the faecal-oral route. Conventional water treatments such as boiling and chlorination can be effective but may prove costly for impoverished communities. Solar water disinfection (SODIS) has been shown to be a cheap and effective way for communities to treat their water. The exposure to sunlight is typically carried out in small volume plastic beverage bottles (up to 2 l). Given the water requirements of consumption and basic personal hygiene, this may not always meet the needs of communities. Recent work has shown 19-L plastic water dispenser containers to be effective SODIS reactors, comparable in efficacy to PET bottles. In this paper we outline the need for studying SODIS in large volumes and discuss 4 main associated challenges.
    Discussion: Apart from clean water needed for consumption, access to adequate water is essential for sanitation and hygiene. Contamination of treated water through unwashed hands or vessels contributes heavily to the spread of water borne pathogens in communities. Traditional water treatments such as boiling and chlorination can be effective but may prove financially burdensome for low income communities. SODIS in large vessels could be used as a simple method to meet water requirements in low income and disaster affected populations. However, there have been some concerns associated with the conventional SODIS method; we identify the main ones to be: (1) cold or cloudy weather; (2) the fear of leaching in plastic bottles; (3) water turbidity, and; (4) community acceptance. The application of SODIS in large bottles like WDCs has the potential to be an efficient and cost effective method of disinfecting water, either for consumption until more rigorous water treatments can be put in place, or for sanitation and hygiene to curb the spread of fecal contamination. Further research is needed that can address some of the limitations and challenges associated with the use of large bottles for SODIS.
