Objective: To determine the effects of circSPECC1 (hsa_circ_0000745) on the proliferation and migration of LNCaP prostate cancer cells and to explore the potential molecular mechanism.
Methods: Stable circSPECC1 shRNA-expressing and circSPECC1-overexpressing LNCaP cell lines were constructed, and relative gene expression levels were determined by RT-PCR. MTT and clonogenic assays were used to assess proliferative ability while a scratch test was used to analyze cell migration. Western blotting was used to determine protein expression levels. The effects of circSPECC1 on the proliferation of LNCaP prostate cancer cells were observed in vivo.
Results: circSPECC1 was found to be derived from the SPECC1 (sperm antigen with calponin homology and coiled-coil domains 1) parent gene and to form a loop. Overexpression of circSPECC1 promoted the proliferation and migration of the LNCaP cells, whereas decreased expression of circSPECC1 inhibited these properties. Overexpression of circSPECC1 promoted the expression of MMP-2, MMP-9, VEGF, vimentin, and N-cad but downregulated the expression of E-cad. Decreased expression of circSPECC1 inhibited the expression of MMP-2, MMP-9, VEGF, vimentin, and N-cad but increased the expression of E-cad.
Conclusion: circSPECC1 promotes cell proliferation and migration by affecting the epithelial-mesenchymal transition of LNCaP prostate cancer cells.

Cervical cancer (CC) is a malignant tumor in females characterized by high incidence and mortality rates, often resulting in a poor prognosis for patients. Zoledronic acid (ZA), a third-generation bisphosphonate, exhibits anti-tumor properties across various types of tumors. To further understand the effect of ZA in the treatment of CC, this article included two kinds of human CC cells (CCCs) as the research object, examining the impact of varying levels of ZA on the cells' biological properties.

A number of various human malignancies have been associated with abnormal microRNAs (miRNA) expression. There are evidence that miR-200 operates as both tumor suppressor and an onco-miR in a variety of tumors. In this study, we evaluated the effects of miR-200 on the proliferation and migration of pancreatic cancer cells, as well as the underlying molecular pathways.

To investigate the role of silent information regulator 6 (SIRT6) in regulating podocyte injury in diabetic nephropathy (DN) through autophagy mediated by Notch signaling pathway. A blank control group (group A), a diabetic nephropathy group (group B), and a Sirt6 intervention group (group C) were established. The group A cells were human normal glomerular podocyte cell lines (HGPCs) without any treatment.

Aims: Human periodontal ligament stem cells (hPDLSCs) exhibit an enormous potential to regenerate periodontal tissue. However, their translatability to the clinical setting is constrained by technical difficulties in standardizing culture conditions. The aim was to assess complex culture conditions using a proteomic-based protocol to standardize multi-layer hPDLSC cultivation methodology.

Background: Magnolia kobus DC (MO), as a plant medicine, has been reported to have various physiological activities, including neuroprotective, anti-inflammatory, and anti-diabetic effects. However, vascular protective effects of MO remain incompletely understood. In this study, we evaluated the vascular protective effect of MO against ferroptosis in a carotid artery ligation (CAL)-induced neointimal hyperplasia mouse model and in aortic thoracic smooth muscle A7r5 cells.
