Gene expression analysis of tumour xenografts after injection of breast cancer cells treated with axolotl oocyte extracts

Project description:Analysis of genes that were differentially expressed in axolotl extract reprogrammed tumour xenografts compared to untreated controls. The study provided insight into the biological processes, signalling pathways and gene networks affected by the oocyte extract treatment which resulted in halted tumour growth in mice.

The axolotl kidney: a novel model to study kidney regeneration

Project description:To investigate whether axolotl could serve as a novel model organism for the study of kidney regeneration after severe renal injury. We established tubular injury model by intraperitoneal injection of gentamicin. We then performed gene expression profiling analysis using data obtained from RNA-seq of 5 different samples from Control or gentamicin-induced injury groups.

Understanding the Mechanistic Contribution of Herbal Extracts in Compound Kushen Injection with Transcriptome Analysis

Project description:Herbal compatibility is the knowledge of which herbs to combine in traditional Chinese medicine (TCM) formulations. The lack of understanding of herbal compatibility is one of the key problems for the application and popularization of TCM in western society. Because of the chemical complexity of herbal medicines, it is simpler to begin to conduct compatibility research based on herbs rather than component plant secondary metabolites. We have used transcriptome analysis to explore the effects and interactions of two plant extracts (Kushen and Baituling) combined in Compound Kushen Injection (CKI). Based on shared chemical compounds and in vitro cytotoxicity comparisons, we found that both the major compounds in CKI, and the cytotoxicity effects of CKI were mainly derived from the extract of Kushen (Sophorae flavescentis). We generated and analyzed transcriptome data from MDA-MB-231 cells treated with single-herb extracts or CKI and results showed that Kushen contributed to the perturbation of the majority of cytotoxicity/cancer related pathways in CKI such as cell cycle and DNA replication. We also found that Baituling (Heterosmilax yunnanensis Gagnep) could not only enhance the cytotoxic effects of Kushen in CKI, but also activate immune-related pathways. Our analyses predicted that IL-1[beta] gene expression was upregulated by Baituling in CKI and we confirmed that IL-1[beta] protein expression was increased using an ELISA assay. Altogether, these findings help to explain the rationale for combining Kushen and Baituling in CKI, and show that transcriptome analysis using single herb extracts is an effective method for understanding herbal compatibility in TCM.

Single-nucleus multiome (RNA+ATAC) sequencing of the axolotl pallium

Project description:In order to understand the genomic and transcriptomic variability of the axolotl pallium, as well as reconstruct their intrinsic gene regulatory networks, we performed single-nucleus multiome sequencing (RNA and open chromatin) of whole axolotl pallium.

Multi-species atlas resolves an axolotl limb development and regeneration paradox

Project description:Humans and other tetrapods are considered to require apical-ectodermal-ridge, AER, cells for limb development, and AER-like cells are suggested to be re-formed to initiate limb regeneration. Paradoxically, the presence of AER in the axolotl, the primary regeneration model organism, remains controversial. Here, by leveraging a single-cell transcriptomics-based multi-species atlas, composed of axolotl, human, mouse, chicken, and frog cells, we first established that axolotls contain cells with AER characteristics. Surprisingly, further analyses and spatial transcriptomics revealed that axolotl limbs do not fully re-form AER cells during regeneration. Moreover, the axolotl mesoderm displays part of the AER machinery, revealing a novel program for limb (re)growth. These results clarify the debate about the axolotl AER and the extent to which the limb developmental program is recapitulated during regeneration.

Construction of the axolotl cell landscape using combinatorial hybridization sequencing at single cell resolution [bulk RNA-seq]

Project description:We adopted a combinatorial hybridization based single-cell RNA-seq method to generate tissue based transcriptome atlas of adult axolotl and whole organism transcriptome atlas of larva axolotl. Gene expression profiling of over 1million single cells across 19 organs constructed the first adult axolotl cell atlas. Comparison between neoteny and metamorphosis organs revealed transcriptome heterogeneity of structural cells in different tissues and a sophisticated regulatory network. Furthermore, we described dynamic gene expression pattern during neotenic larva axolotl limb development. These data serve as a rich resource to explore molecular identity of axolotl as well as its metamorphosis.
