Project description:In this study, proteomic analysis on ZIKV-infected primary human fetal neural progenitor cells (NPCs) revealed that virus infection altered levels of cellular proteins involved in NPC proliferation, differentiation and migration.
Project description:To find the influence of mitochondrial hTERT on glucose metabolism and chemoresistance and to further investigate the underlying mechanism.
Project description:The 293T cells overexpressing human telomerase reverse transcriptase (hTERT) were lysed and co-immunoprecipitation was performed using hTERT antibody. Then protein mass spectrum was conducted in order to identify the hTERT-interacting proteins.
Project description:the proteome of skin lesions from HHD patients was assembled and used for iTRAQ to analyze changes in skin lesions compared with unaffected individuals.
Project description:Subversion of the host cytoskeleton is a critical virulence mechanism used by a variety of intracellular bacterial pathogens during their infectious life cycles. Growing evidence suggests that the tactics employed by pathogens are surprisingly diverse. Using proteomic and biochemical methods, we demonstrate that the S. Tm type III effector protein SopB potently interacts specifically with host cell IFs vimentin. After host cell entry, Salmonella replicates in Salmonella containing vacuoles (SCVs), which accumulate a dense meshwork of vimentin through the Salmonella SPI-1 type III secretion effector SopB. We also demonstrate an important role for SopB-vimentin interaction, in the cellular responses including pro-inflammatory cytokine production induced by Salmonella. Vimentin interacts with the N-terminus of the S. Tm T3SS effector protein SopB. Vimentin and its interaction with SopB are dispensable for S. Tm invasion, but are required for stable formation of SCVs which are essential for bacteria replication. Moreover, SopB lacking of N-terminus cdc42-binding domain loses the interaction with vimentin, suggesting that the small GTPase is critical in SopB triggered vimentin recruitment to form integrative SCVs. These findings establish that SCVs integrity of the bacterium specifically requires intermediate filaments vimentin, which is a prerequisite for highly efficient S. Tm replication.
Project description:The regulatory effects of uneven phosphorus supplies on phosphorus transport in soybean roots is still unclear. To further analyze the regulatory effects of low-phosphorus stress on phosphorus transport in soybean roots and the effects of uneven phosphorus application on the physiological mechanism of phosphorus transport in soybean roots, dual-root soybean plants were prepared via grafting, and a sand culture experiment was performed.
Project description:All T. mercedesae samples were collected from capped brood cells using a soft paintbrush and soft tweezers. Reproductive mites (Rep) were collected from brood cells containing white-eyed pupae. Protonymphs (Pro) and one deutonymphs (Deu) were sampled from brood cells containing purple-eyed pupae. Adult T. mercedesae (Adu) were collected from cells close to emerge (about one day before adult bees emerge). For each group (protonymphs, deutonymphs, adults, and reproductive mites), collected mites from all 12 colonies were randomly allocated to one of three replicates (50 mg for each replicate). All samples were rinsed with PBS and air-dried to remove many contaminates that may have been attached to the cuticle, flash-frozen using liquid nitrogen, and stored at -80°C for further processing.
Project description:E.coli ATCC 25922 was overnight grown in 10 ml LB and passaged for 3 h with 1:50 dilution in fresh LB. Treated with tavaborole alone (80 μg/ml, labeled ‘A’) or tavaborole plus amikacin (80 μg/ml +40 μg/ml, labeled ‘AK’) for 6 h, cells were washed in PBS and harvested by centrifugation at 4,000 g, 8 min. After liquid nitrogen flash freezing, cells were stored at -80 °C and transported to company for following experiments
