Hematogenous metastasis is the main approach for colorectal cancer liver metastasis (CRCLM). However, as the gatekeepers in the tumor vessels, the role of TPCs in hematogenous metastasis remains largely unknown, which may be attributed to the lack of specific biomarkers for TPC isolation. Here, microdissection combined with a pericyte medium-based approach is developed to obtain TPCs from CRC patients. Proteomic analysis reveals that TRP channel-associated factor 2 (TCAF2), a partner protein of ...[more]

Comparative microarray analysis of NaV1.8-expressing DRG neurons and cold-sensitive non-NaV1.8-expressing DRG neurons

Project description:The vast majority of cold sensitive DRG neurons from mice do not express the voltage-gated sodium channel NaV1.8. Therefore, we aimed to compare the molecular profiles of NaV1.8 and non-NaV1.8-expressing neurons using microarray analysis. Fluorescent activated cell sorting was performed at 4 degrees centigrade on acutely dissociated DRG neurons from mice expressing NaV1.8-Cre, Pirt-GCaMP3 and a Cre-dependent global reporter (td tomato). NaV1.8-expressing neurons were sorted based on their reporter fluorescence (td tomato; red) and putative cold sensing neurons were sorted based on their GCaMP3 fluorescence at 4 degrees centigrade and absence of Cre-dependent reporter fluorescence. A total of three mice were used (samples one, two and three) with GCaMP3 only and NaV1.8-expressing neurons forming two relative populations within each sample (eg. GC3 one is the experimental counterpart of Tom one).

TGF-beta-mediated microRNA expression in breast cancer cells

Project description:We utilized 3D-organotypic cultures whose physical properties were altered by inclusiong of type I collagen to create biomechanically rigid microenvironments that approximated those typically observed in primary mammary tumors. Compliant 3D-organotypic cultures were also generated to recapitulate the biomechanical properties of pulmonary microenvironments typically encountered by disseminated breast carcioma cells. The murine 4T1 progression series represents an established model of triple negative breast cancer development and metastasis and consists of isogenically-derived nonmetastatic 67NR, systemically invasive 4TO7, and highly metastatic 4T1 cells that were propagated for 6 days in the absense or presense of TGF-beta in either rigid or compliant 3D-cultures. Afterward, total RNA was extracted and subjected to miRNA profiling. two replicates of each growth and treatment condition for each cell line.

Phosphoproteomics Data of pancreatic cancers cells treated with anlotinib

Project description:Aberrant regulation of angiogenesis involves in the growth and metastasis of tumors, but angiogenesis inhibitors fail to improve overall survival of pancreatic cancer patients in previous phase III clinical trials. A comprehensive knowledge of the mechanism of angiogenesis inhibitors against pancreatic cancer is helpful for clinical purpose and for the selection of patients who might benefit from the inhibitors. In this work, multi-omics analyses (transcriptomics, proteomics and phosphoproteomics profiling) were carried to delineate the mechanism of anlotinib, a novel angiogenesis inhibitor, against pancreatic cancer cells.

Transcription factors MYOCD, SRF, Mesp1 and SMARCD3 significantly enhance the cardio-inducing effect of GATA4, TBX5, and MEF2C during direct cellular reprogramming

Project description:Transient over-expression of defined combinations of master regulator genes can effectively induce cellular reprogramming: the acquisition of an alternative predicted phenotype from a differentiated cell lineage. This can be of particular importance in cardiac regenerative medicine wherein the heart lacks the capacity to heal itself, but simultaneously contains a large pool of fibroblasts. In this study we determined the cardio-inducing capacity of ten transcription factors to actuate cellular reprogramming of mouse embryonic fibroblasts into cardiomyocyte-like cells. Over-expression of transcription factors MYOCD and SRF alone or in conjunction with Mesp1 and SMARCD3 significantly enhanced the basal but necessary cardio-inducing effect of the previously reported GATA4, TBX5, and MEF2C. In particular, combinations of five or seven transcription factors significantly enhanced the activation of cardiac reporter vectors, and induced an upregulation of cardiac-specific genes. Global gene expression analysis also demonstrated a significantly greater cardio-inducing effect when the transcription factors MYOCD and SRF were used. Detection of cross-striated cells was highly dependent on the cell culture conditions and was enhanced by the addition of valproic acid and JAK inhibitor. Although we detected Ca2+ transient oscillations in the reprogrammed cells, we did not detect significant changes in resting membrane potential or spontaneously contracting cells. This study further elucidates the cardio-inducing effect of the transcriptional networks involved in cardiac cellular reprogramming, contributing to the ongoing rational design of a robust protocol required for cardiac regenerative therapies. Mouse embryonic fibroblasts were transduced lentiviruses allowing the inducible overexpression of three unique sets of transcription factors and negative control. A total of four experimental groups which included three biological replicates in each.

Matrix Metalloproteinase-7 in Urinary Extracellular Vesicles Identifies Rapid Disease Progression in Autosomal Dominant Polycystic Kidney Disease

Project description:Background: In autosomal dominant polycystic kidney disease (ADPKD) there is an unmet need for early markers of rapid disease progression to facilitate counseling and selection for kidney-protective therapy. Our aim was to identify markers for rapid disease progression in urinary extracellular vesicles (uEVs). Methods: uEVs were isolated at baseline in two independent cohorts including patients with rapid disease progression and stable disease; patients were matched by age, sex, total kidney volume and mutation. uEV biomarker candidates were identified by mass spectrometry and further analyzed in a third and fourth cohort using immunoblotting and an enzyme-linked immunosorbent assay (ELISA). Single-nucleotide RNA sequencing of healthy and ADPKD tissue was used to confirm findings and identify the cellular origin of the uEV biomarker. Results: In the first two cohorts matrix metalloproteinase-7 (MMP-7) was significantly higher in uEVs of patients with rapid disease progression compared to stable disease. In the third cohort, immunoblotting confirmed a >2-fold increase in uEV-MMP-7 in patients with rapid disease progression compared to stable disease. In the fourth cohort, whole urine rather than uEVs were analyzed with MMP-7 ELISA demonstrating a significant but weak correlation with kidney function decline. Single-nucleotide RNA sequencing showed higher MMP-7 expression in ADPKD kidney tissue than in healthy kidney tissue and localized MMP-7 to the proximal tubule and thick ascending limb. Conclusion: uEV-associated MMP-7 is elevated in ADPKD patients with rapid disease progression and should be further investigated as predictive biomarker. Our findings also suggests that MMP-7 performs better when analyzed in uEVs than in whole urine.
