Project description:The Herbal Formula YYJD inhibit migration and invasion of lung adenocarcinoma cells, we aims to profile a comprehensive alternative polyadenylation (APA) dynamic pattern of Lung Adenocarcinoma Cells under YYJD treatment unsing 3T-seq method.
Project description:Transitional Chinese herbal medicine has a long history of applications for anti-aging and longevity purposes, and in our patent formula Gancao Nurish-Yin (GCNY) decoction, all of the ingredients show antioxidant properties. However, in real clinical practice, extractions of herbs are rarely applied alone but are prescribed as integrated formula. In order to investigate whether GCNY possess anti-oxidation potential, we applied GCNY as a formula to treat rats in order to acquire medicated serum, which was then added on H2O2 (200 μM)-modeled human microglial cell line HMC-3 in comparison with its controls.
Project description:The Chinese herbal granule Tangshen Formula (TSF) has been proven to decrease proteinuria and improve estimated glomerular filtration rate (eGFR) in diabetic kidney disease (DKD) patients with albuminuria. Nevertheless, little was known on the underlying mechanisms of TSF on treating DN. We used microarrays to detail to explore the target genes of TSF in the treatment of DN.
Project description:Some chemotherapy drugs influence the formation of stress granules (SGs), cytoplasmic RNA foci involved in stress response pathways. The exact role of SGs in promoting cell survival or apoptosis needs further clarification. The chemotherapy drug lomustine induces SG formation by activating the eIF2α kinase HRI (EIF2AK1). We performed a DNA microarray transcriptome analysis to identify genes affected by lomustine-induced stress and to explore the role of SGs. Our findings show that lomustine specifically regulates the expression of the pro-apoptotic EGR1 gene. The presence of EGR1 mRNA in SGs correlates with reduced translation of EGR1 mRNA. Lomustine likely sequesters EGR1 mRNA into SGs, preventing its ribosomal translation and thereby limiting apoptosis. This supports a model where SGs selectively sequester specific mRNAs in response to stress, modulate their translation, and thus determine the fate of stressed cells.
