Recruitment of mesenchymal stem cells (MSC) to tissue damages is a promising approach for in situ tissue regeneration. The physiological mechanisms and regulatory processes of MSC trafficking to injured tissue remain poorly understood. However, the pivotal role of chemokines in MSC recruitment has already been shown. The aim of this study was to determine the migratory potential and the gene expression profile of MSC stimulated with the CC chemokine CCL25 (TECK). Bone marrow derived human MSC were exposed to different doses of CCL25 in a standardized chemotaxis assay. Microarray gene expression profiling and pathway analysis were performed for CCL25 stimulated MSC. Maximum migration of MSC towards CCL25 was observed at 10(3) nM. Microarray analysis revealed an induction of molecules directly involved in chemotaxis and homing of bone marrow cells (CXCL1-3, CXCL8, PDE4B), cytoskeletal and membrane reorganisation (CXCL8, PLD1, IGFBP1), cellular polarity (PLD1), and cell movement (CXCL1-3, CXCL6, CXCL8, PTGS2, PDE4B, TGM2). Respective chemokine secretion was confirmed by protein membrane-array analysis. The activation of CXCR2 ligands (CXCL1-3, CXCL5-6, CXCL8) and a LIF-receptor/gp130 ligand (LIF) indicated an involvement of the respective signaling pathways during initiation of chemotaxis and migration. These results suggest CCL25 as a new potential candidate for further in situ regeneration approaches.

Cystic fibrosis (CF) is caused by mutations in the (). While gene therapy holds promise as a cure, the cell-type-specific heterogeneity of expression in the lung presents significant challenges. Current CF ferret models closely replicate the human disease phenotype but have limitations in studying functional complementation through cell-type-specific CFTR restoration.

Epidermal growth factor (EGF) binds with its surface receptor to stimulate gene expression and cancer cell proliferation. EGF stimulates cancer cell growth via phosphoinositide 3‑kinase (PI3K) and programmed cell death ligand 1 (PD‑L1) pathways. As an integrin αvβ3 antagonist, heteronemin exhibits potent cytotoxic effects against cancer cells.

Oral squamous cell carcinoma (OSCC) is a type of head and neck cancer (HNC) with a high recurrence rate, which has been reported to be associated with the presence of cancer stem cells (CSCs). Tribbles pseudokinase 3 (TRIB3) is involved in intracellular signaling and the aim of the present study was to investigate the role of TRIB3 in the maintenance of CSCs. Analysis of The Cancer Genome Atlas database samples demonstrated a positive correlation between TRIB3 expression levels and shorter overall survival rates in patients with HNC.

Pancreatic cancer is an aggressive tumor, which is often associated with a poor clinical prognosis and resistance to conventional chemotherapy. Therefore, there is a need to identify new therapeutic markers for pancreatic cancer. Although KIN17 is a highly expressed DNA‑ and RNA‑binding protein in a number of types of human cancer, its role in pancreatic cancer development, especially in relation to progression, is currently unknown.
