Breast cancer is one of the most commonly diagnosed cancers in woman which accounts for more than 1 in 10 new cancers in the entire world. The recently found four new potential hub genes that show a strong expression in breast cancer are CCNA2, CCNB1, MAD2L1, and RAD51. Nowadays, food habits and lifestyle of an individual are one of the factors for causing cancers. Consumption of seeds on a regular basis is the key factor for leading a good health. Sesame seeds and Sunflower seeds are few examples of cancer fighting seeds. Sesame (Sesamum indicum) is one of the earliest oil seed plant with various phytocompounds present which include lignans, tocopherols, phenolics, polyunsaturated fatty acids, and phytosterols. Sunflower (Helianthus annuus L.) is primarily harvested as an oil seed plant with various phytocompounds present which include flavonoids, phenolic acids, tocopherols, and vitamin B3. These are the few seeds that help women to prevent and also to fight against Breast cancer with its potential anti-cancer activity. The main objective of the current study is to identify the potential phytocompounds present in the cancer fighting seeds using molecular docking and dynamic simulation approach which can further help pharmaceuticals industries in producing targeted drugs against breast cancer hub genes as well as food industries in producing products combining the potential phytocompounds present in the seeds.Metal-organic frameworks (MOFs) can be used as the immobilization carriers to protect the physicochemical properties of enzymes and improve their catalytic performance. Herein, we report an in situ co-precipitation method to immobilize lipase from Candida sp. 99-125 in Cu-BTC MOF (BTC = 1, 3, 5-benzene tricarboxylic acid, H3BTC). Characterizations of the immobilized lipase (lipase@Cu-BTC) have confirmed the entrapment of lipase molecules in Cu-BTC MOF. The immobilized lipase has been successfully applied for resolving N-hydroxymethyl vince lactam (N-HMVL) and its catalytic activity is five times that of native enzyme. More importantly, we found that Cu-BTC MOF can afford powerful protection for enzyme in nearly dry organic solvent and endow the immobilized lipase with excellent reusability and storage stability. Our present study may widen the application of immobilized enzyme with MOF as the immobilized carrier.In this study, a newly isolated strain Filobasidium magnum JD1025 was investigated for its production of sclareolide, which was verified to be a valuable raw material in various industrial fields. Together with a comprehensive analysis of the genome sequence, effective fermentation method to convert sclareol to sclareolide via the isolated strain was explored and optimized by taking the selected co-solvent and nitrogen source into account. The results showed that the final conversion rate could be achieved at 88.79 ± 1.06% with the initial sclareol concentration of 30 g·L-1 after 72 h in baffled flask. The corresponding yield concentration of sclareolide was 21.62 ± 0.26 g·L-1 and the conversion rate per unit thallus attained to 6.11 ± 0.06 % g-1·L-1. Overall, the current study suggested a valid method for the application of Filobasidium magnum JD1025 as bio-transformer to produce sclareolide from sclareol.Leonotis nepetifolia (L.) R.Br. is a medicinally important herb belonging to the family Lamiaceae. The plant is typically found in tropical regions, and its leaf and root extracts are renowned for their ethno-botanical and therapeutic applications. This study was designed to determine the presence of various bioactive components, and to evaluate antibacterial, antifungal, antioxidant, and anti-proliferative activities. The preliminary phytochemical screening and gas chromatography-mass spectrometry (GC-MS) analysis of different solvent extracts revealed the presence of various bioactive compounds, of which methanol extract showed 24 compounds, petroleum ether extract revealed 26 compounds, and 24 compounds in hexane extracts. The major bioactive components including λ-sitosterol (16.20 %) in methanol extract, 1-nonadecanol (15.48 %) in petroleum extract, and eicosane (13.22 %) in hexane extract have been reported with various bio-therapeutic applications. In addition, the flower bud methanolic extract of L. CC-99677 molecular weight nepetifolia exhibited inhibitory potential against all tested bacterial and fungal pathogens. The DPPH radical scavenging assay revealed that methanolic extract possessed the highest antioxidant activity. The scavenging activity increased in a concentration-dependent manner, as indicated by a 74 % inhibition rate at 1000 µg/ml. Furthermore, the in vitro cytotoxic effects of the methanolic extract on the HepG2 cell line were evaluated. The IC50 value of methanolic extract against HepG2 cells was determined to be 83.28 µg/ml. The findings reveal that different solvent extracts of L. nepetifolia flower buds contain a significant amount of various bioactive phytochemicals with antioxidant and anticancer activities; and thus, the plant could serve as a potential source of pharmacological applications.The World Health Organization (WHO) reports that the emergence of multidrug-resistant and the slow advent of novel and more potent antitumor and antimicrobial chemotherapeutics continue to be of the highest concern for human health. Additionally, the stability, low solubility, and negative effects of existing drugs make them ineffective. Studies into alternative tactics to tackle such tenacious diseases was sparked by anticancer and antibacterial. Silver (Ag) and gold (Au) nanoparticles (NPs) were created from Trichoderma saturnisporum, the much more productive fungal strain. Functional fungal extracellular enzymes and proteins carried out the activities of synthesis and capping of the generated nano-metals. Characterization was done on the obtained Ag-NPs and Au-NPs through UV-vis, FTIR, XRD, TEM, and SEM. Additionally, versus methicillin-sensitive Staphylococcus aureus (MSSA) and methicillin-resistant Staphylococcus aureus (MRSA), Pseudomonas aeruginosa, and Klebsiella pneumoniae, the antibacterial activities of Ag-NPs and Au-NPs were assessed. In particular, the Ag-NPs were more effective against pathogenic bacteria than Au-NPs. Furthermore, antibiofilm study that shown Au-NPs had activity more than Ag-NPs. Interestingly, applying the DPPH procedure, these noble metallic NPs had antioxidant activity, in which the IC50 for Ag-NPs and Au-NPs was 73.5 μg/mL and 190.0 μg/mL, respectively. According to the cytotoxicity evaluation results, the alteration in the cells was shown as loss of their typical shape, partial or complete loss of monolayer, granulation, shrinking, or cell rounding with IC50 for normal Vero cell were 693.68 μg/mL and 661.24 μg/mL, for Ag-NPs and Au-NPs, respectively. While IC50 for cancer cell (Mcf7) was 370.56 μg/mL and 394.79 μg/mL for Ag-NPs and Au-NPs, respectively. Ag-NPs and Au-NPs produced via green synthesis have the potential to be employed in the medical industry as beneficial nanocompounds.This study investigates the effect and mechanism of proprotein convertase subtilisin/Kexin type 9 (PCSK9) on myocardial ischemia-reperfusion injury (MIRI) and provides a reference for clinical prevention and treatment of acute myocardial infarction (AMI). We established a rat model of myocardial ischemia/reperfusion (I/R) and AC16 hypoxia/reoxygenation (H/R) model. A total of 48 adult 7-week-old male Sprague-Dawley rats were randomly assigned to three groups (n = 16) control, I/R, and I/R + SiRNA. In I/R and I/R + siRNA groups, myocardial ischemia was induced via occlusion of the left anterior descending branch (LAD) of the coronary artery in rats in I/R group for 30 min and reperfused for 3 days. To assess the myocardial injury, the rats were subjected to an electrocardiogram (ECG), cardiac function tests, cardiac enzymes analysis, and 2,3,5-triphenyl tetrazolium chloride (TTC)/Evan Blue (EB) staining. Meanwhile, differences in the expression of autophagy-level proteins and Bcl-2/adenovirus E1B 19-kDa interacting protein (Bnip3) signaling-related proteins were determined by protein blotting. In vitro and in vivo experimental studies revealed that siRNA knockdown of PCSK9 reduced the expression of autophagic protein Beclin-1, light chain 3 (LC3) compared to normal control-treated cells and control-operated groups. Simultaneously, the expression of Bnip3 pathway protein was downregulated. Furthermore, the PCSK9-mediated small interfering RNA (siRNA) group injected into the left ventricular wall significantly improved cardiac function and myocardial infarct size. In ischemic/hypoxic circumstances, PCSK9 expression was dramatically increased. PCSK9 knockdown alleviated MIRI via Bnip3-mediated autophagic pathway, inhibited inflammatory response, reduced myocardial infarct size, and protected cardiac function.

DESTINY-Breast01 (NCT03248492) is a phase II single-arm trial evaluating trastuzumab deruxtecan (T-DXd) in adults with human epidermal growth factor receptor 2-positive (HER2+) unresectable or metastatic breast cancer (u/mBC) who have received two or more prior anti-HER2 therapies.

Objectives were to explore approaches for estimating long-term overall survival (OS) with T-DXd from immature data (June 2020 data-cut; median follow-up 20.5months), and compare predicted long-term outcomes with UK-recommended non-targeted therapies eribulin, capecitabine, and vinorelbine.

Two methods were used to model T-DXd long-term OS (1) applying a hazard ratio (HR) to the OS curve for another HER2 targeted therapy (third-line trastuzumab emtansine [T-DM1]) with longer trial follow-up; and (2) extrapolating T-DXd OS data directly. Comparator OS was based on direct extrapolation of published data (comparison with vinorelbine OS was not possible). Quality-adjusted life years (QALYs) were calculated using a previously publiapproach in which an HR was applied to the T-DM1 OS curve informed a submission to the National Institute for Health and Care Excellence.The browning of white adipose tissue (WAT) has attracted considerable attention in the scientific community as a popular strategy for enhancing energy expenditure to combat obesity. As a part of this strategy, β3-adrenergic receptor (β3-AR) is the most widely studied receptor that mediates thermogenesis. Parenthetically, further studies in search for additional receptors expressed in adipocytes that can mediate thermogenesis has been appearing, and this paper reports that dopaminergic receptor 1 (DRD1) and β3-AR synergistically stimulate browning in 3T3-L1 white adipocytes. qRT-PCR and immunoblot analysis methods were applied to evaluate the effects of DRD1 on the target proteins downstream of β3-AR and other markers involved in lipid metabolism, mitochondrial biogenesis, and browning events. These results show that DRD1 is expressed in epididymal WAT (eWAT), brown adipose tissue (BAT), and inguinal WAT (iWAT) of normal and high-fat-fed mice, and a deficiency of DRD1 downregulates the expression of brown adipocyte-specific proteins. Silencing of DRD1 affected lipid metabolic activity in 3T3-L1 adipocytes by reducing mitochondrial biogenesis as well as levels of lipolytic and fat oxidative marker proteins in a similar pattern to β3-AR. Moreover, mechanistic studies showed that the depletion of DRD1 downregulates β3-AR and its downstream molecules, suggesting both receptors might synergistically stimulate browning. Parallel to the UCP1-dependent thermogenesis, the depletion of DRD1 also downregulates the expression of core proteins responsible for UCP1-independent thermogenesis. Overall, DRD1 mediates β3-AR-dependent 3T3-L1 browning and UCP1-independent thermogenesis.
