The Integrated Islet Distribution Program (IIDP), a major source for human islet distribution for over 15 years, conducted a study to evaluate the most advantageous times to ship islets postisolation to maximize islet recovery. For the evaluation, three experienced IIDP Islet Isolation Centers each provided samples from five human islet isolations, shipping 10,000 islet equivalents (IEQ) at four different time periods postislet isolation (no 37°C culture and shipped within 0 to 18 hours; or held in 37°C culture for 18 to 42, 48 to 96, or 144 to 192 hours). A central evaluation center compared samples for islet quantity, quality, and viability for each experimental condition preshipment and postshipment, as well as post 37°C culture 18 to 24 hours after shipment receipt. Additional evaluations included measures of functional potency by static glucose-stimulated insulin release (GSIR), represented as a stimulation index. Comparing the results of the four preshipment holding periods, the greatest IEQ loss postshipment occurred with the shortest preshipment times. Similar patterns emerged when comparing preshipment to postculture losses. In vitro islet function (GSIR) was not adversely impacted by increased tissue culture time. These data indicate that allowing time for islet recovery postisolation, prior to shipping, yields less islet loss during shipment without decreasing islet function.This study aimed to explore the characteristics of TGFBR1-epidermal growth factor receptor (EGFR)-CTNNB1-CDH1 axis in regulating the invasion and migration in lung cancer. Using the small interfering RNA technology, EGFR was silenced in H2170 and H1299 cells. Then, the colony formation, migration, and invasion abilities were detected using colony-forming assay and transwell assay. Moreover, the mRNA expression of smad2, smad3, CTNNB1, and CDH1, and the protein expression of TGFBR1, CDH1, and TCF were determined using the real-time polymerase chain reaction and western blotting. The results showed that silencing EGFR could significantly decrease the colony-forming ability in H2170 and H1299. Knocking down EGFR could significantly inhibit the invasion and migration ability of H2179 and H1299. Inhibiting the expression of EGFR could significantly decrease the expression of smad2, smad3, CDH1, and CTNNB1, with all P-values less then 0.05. In addition, silencing EGFR could markedly decrease the expression of TGFBR1 and CDH1 in H1299 and H2170, with all P-values less then 0.05. In conclusion, silencing EGFR could significantly regulate the progression of lung cancer via TGFBR1-EGFR-CTNNB1-CDH1 axis in Wnt signaling pathway.Cancer-associated fibroblasts (CAFs) are the major constituents of the tumor microenvironment and promote cancer development via tumor-stromal interactions. The alteration of microRNA (miRNA) expression in fibroblasts can induce the phenotype conversion between normal fibroblasts and CAFs in certain tumor types. However, the mechanisms underlying the phenotype conversion of fibroblasts in colorectal cancer (CRC) are largely unknown. Our study focuses on the role of miR-1246 in fibroblasts-CRC cells interaction. In this study, CCD-18Co colorectal fibroblasts were cultured in the conditioned medium (CM) derived from CRC cells to obtain the CAF phenotype. We found that the miR-1246 expression was upregulated in CAF-like fibroblasts compared with normal fibroblasts. miR-1246 secreted by cancer cells could be utilized by neighboring fibroblasts for CAF reprogramming. On the other hand, following secretion by CAF-like fibroblasts, miR-1246 was delivered into CRC cells and promoted cell migration via the activation of the Wnt/β-catenin signaling in CRC cells. Furthermore, high miR-1246 expression in CRC tissues was negatively associated with disease-free survival (DFS) for CRC patients. Taken together, our results reveal that miR-1246 can shuttle between CRC cells and fibroblasts. This study also indicates that targeting miR-1246 or blocking its transport from CAFs to CRC cells might represent a novel therapeutic approach in CRC treatment.Bone is a common site of metastasis for various types of cancer cells, including breast cancer, and the consequent skeleton-related events observed in patients are severe and often fatal. Currently, it is widely accepted that cancer-associated fibroblasts (CAFs) confer a metastasis-promoting property to breast cancer cells. Furthermore, clinical observations suggest that CAFs mediate the bone tropism of metastatic breast cancer cells. Therefore, a deeper understanding of the mechanism by which CAFs are involved in the bone-tropic metastasis of breast cancer can facilitate the study of the novel and effective therapeutic drugs for the corresponding targets. In this review, we focused on the coordinator role of CAFs in remolding breast cancer cells and remodeling the bone marrow during metastasis. We discussed the potential roles of the CXCL12/CXCR4 axis, the CAFs-CSCs reinforcing loop, and exosomes in this malignant process. In summary, in agreement with Paget's theory, CAFs play a pivotal role in bone colonization by breast cancer cells by providing a "fertile soil" for the "selected seeds" by influencing tumor-intrinsic characteristics and microenvironment (ME).
