Objectives: Nowadays cancer treatment is an important challenge in the medical world that needs better therapies. Many active secretions produced by insects such as honey bees used to discover new anticancer drugs. Bee venom (BV) has a potent anti inflammatory, anti cancer and tumor effects. The aim of present study is evaluation of anticancer effects induced by venom (AmV) on cell Lines.
Methods: AmV was selected for study on cancer cell lines. Total protein, molecular weight and LD of crude venom were determined. Then, cells were grown in Dulbecco's Modified Eagle medium supplemented with 10% fetal bovine serum and 1% antibiotics. The A, HeLa and MDA-MB-231 cell Lines were exposed by different concentration of AmV. The morphology of cells was determined and cell viability was studed by MTT assay. Evaluation of cell death was determined by and DNA fragmentation.
Results: The results from MTT assay showed that 3.125 µg/mL of A, 12.5 for HeLa and 6.25 µg/mL of MDA-MB-231 killed 50% of cells (p < 0.05). Morphological analysis and the results from hoescht staining and DNA fragmentation indicated that cell death induced by AmV was significantly apoptosis.
Conclusion: The data showed that using lower dosage of AmV during treatment period cause inhibition of proliferation in time and dose dependant manner. Findings indicated that some ingredients of AmV have anticancer effects and with further investigation it can be used in production of anticancer drugs.

With the advancements of next-generation sequencing, publicly available pharmacogenomic datasets from cancer cell lines provide a handle for developing predictive models of drug responses and identifying associated biomarkers. However, many currently available predictive models are often just used as black boxes, lacking meaningful biological interpretations. In this study, we made use of open-source drug response data from cancer cell lines, in conjunction with KEGG pathway information, to develop sparse neural networks, K-net, enabling the prediction of drug response in EGFR signaling pathways and the identification of key biomarkers.

Human intestinal permeability is a key determinant of the oral fraction absorbed () of active pharmaceutical ingredients (APIs). This study evaluated the ability of an in-house canine Mdr1 (cMdr1) knockout (KO) Madin-Darby Canine Kidney (MDCK) cell line to correlate apparent permeability () with human small intestinal permeability (). values of 16 reference compounds with high, medium, or low permeabilities were measured in the in-house cMdr1 KO MDCK protocol under pH gradient (6.

The coordination of floral developmental stages with the environment is important for reproductive success and the optimization of crop yields. The timing of different developmental stages contributes to final yield potential with optimal adaptation enabling development to proceed without being impacted by seasonal weather events, including frosts or end of season drought. Here we characterise the role of FLOWERING LOCUS T 3 (FT3) in hexaploid bread wheat (Triticum aestivum) during the early stages of floral development.

It has become evident from decades of clinical trials that multimodal therapeutic approaches with focus on cell intrinsic and microenvironmental cues are needed to improve understanding and treat the rare, inoperable, and ultimately fatal diffuse intrinsic pontine glioma (DIPG), now categorized as a diffuse midline glioma. In this study we report the development and characterization of an in vitro system utilizing 3D Tumor Tissue Analogs (TTA), designed to replicate the intricate DIPG microenvironment. The innate ability of fluorescently labeled human brain endothelial cells, microglia, and patient-derived DIPG cell lines to self-assemble has been exploited to generate multicellular 3D TTAs that mimic tissue-like microstructures, enabling an in- depth exploration of the spatio-temporal dynamics between neoplastic and stromal cells.

There are no proven therapies for metastatic or unresectable Chromophobe Renal Cell Carcinoma (ChRCC). ChRCC is characterized by high glutathione levels and hypersensitivity to ferroptosis, an iron-dependent form of cell death characterized by peroxidation of polyunsaturated fatty acids. The underlying mechanisms leading to ferroptosis hypersensitivity are unknown.
