Objective: To explore that the arsenic trioxide injection (ATI) has the effect in antagonizing adhesion and invasion of human hepatocarcinoma cells (HCC), and its relevant mechanism.
Methods: Human hepatocellular carcinoma cell line SMMC-7721 and the high metastatic nude mice human HCC in situ transplantation model was taken as the objects of study, the effects of ATI on the SMMC-7721 cell movement and migration, its adhesion with fibronectin (FN) and endothelial cell (EC), as well as the CD44 and MMP-2 gene protein expression in transplanted tumor of the model mice were observed by means of cell movement and migration test, cell adhesion test and immunohistochemical method.
Results: ATI could significantly inhibit SMMC-7721 cell movement and migration on FN, adhesion with FN and EC, also could lower CD44 and MMP-2 in cancer cells.
Conclusion: ATI has the effects of antagonizing hepatocarcinoma cell adhesion and invasion, the mechanism may be related with the action of ATI in lowering CD44 and MMP-2 expression in cancer cells.

Translocation across barriers and through constrictions is a mechanism that is often used in vivo for transporting material between compartments. A specific example is apicomplexan parasites invading host cells through the tight junction that acts as a pore, and a similar barrier crossing is involved in drug delivery using lipid vesicles penetrating intact skin. Here, we use triangulated membranes and energy minimization to study the translocation of vesicles through pores with fixed radii.

To investigate the correlation between uterine volume and intrauterine adhesion (IUA). From June 2018 to November 2019, totally 7 007 patients who underwent hysteroscopy in outpatient operating rooms of Gynecological Minimally Invasive Center, Beijing Obstetrics and Gynecology Hospital were retrospectively analyzed Patients of reproductive age with IUA without uterine fibroids and adenomyosis were selected as IUA group, and patients of reproductive age without uterine fibroids and adenomyosis without IUA during the same period were selected as the control group. The propensity score matching (PSM) method was used to perform 1∶1 matching for the two groups of patients, matching variables included age, height, weight, body mass index (BMI), gravidity, parity, and number of abortion curettage.

Collective cell migration is a fundamental process underlying various biological phenomena, including embryonic development and cancer cell invasion. The cohesive yet flexible movement of cell collectives largely depends on the coordinated regulation of cell-cell and cell-substrate adhesions. In this review, we summarize the regulation of key cell-cell junction components, such as cadherins and zonula occludens proteins during collective cell migration, with a particular focus on the recently discovered multifaceted roles of ZO-1 in both cell-cell and cell-substrate interactions.

The application of light-responsive nanomaterials (LRNs) in bone tissue engineering shows broad prospects, especially in promoting bone healing and regeneration. With a deeper understanding of the mechanisms of bone defects and healing disorders, LRNs are receiving increasing attention due to their non-invasive, controllable, and efficient properties. These materials can regulate cellular biological reactions and promote bone cell adhesion, proliferation, and differentiation by absorbing specific wavelengths of light and converting them into physical and chemical signals.

To develop and evaluate graphene oxide/gelatin/alginate scaffolds for advanced wound therapy capable of mimicking the native extracellular matrix (ECM) and bio-stimulating all specific phases of the wound healing process, from inflammation and proliferation to the remodeling of damaged skin tissue in three dimensions. The scaffolds were engineered as interpenetrating polymeric networks by the crosslinking reaction of gelatin in the presence of alginate and characterized by structural, morphological, mechanical, swelling properties, porosity, adhesion to the skin tissue, wettability, and in vitro simultaneous release of the active agents. Biocompatibility of the scaffolds were evaluated in vitro by MTT test on fibroblasts (MRC5 cells) and in vivo using assay.
