Article Abstract
Objective: To explore the mechanism by which hsa_circ_0005325 affects the proliferation, apoptosis, colony formation, migration, and angiogenesis-promoting behavior of oral squamous cell carcinoma cells through the miR-433-3p/HMGA2 axis.
Material And Methods: qRT‒PCR was used to measure the expression of hsa_circ_0005325 in SCC25 and CAL-27 cells and normal human oral epithelial cells (HOK). SCC25 and CAL-27 cells were cultured, and Cell Counting Kit-8 (CCK-8), cell apoptosis, plate colony formation, Transwell migration and a tube formation assays were used to detect changes in cell proliferation, apoptosis, colony formation, migration and angiogenesis, respectively.
Results: The expression of hsa_circ_0005325 was significantly increased in SCC25 and CAL-27 cells. Compared with those in the sh-NC group, the percentages of apoptotic SCC25 and CAL-27 cells in the sh-circ_0005325 group were significantly greater, and their proliferation, colony formation, migration and angiogenesis capacities were significantly lower (p < 0.05). Moreover, the protein expression level of HMGA2 was significantly decreased, and the expression level of miR-433-3p was significantly increased in the sh-circ_0005325 group versus the control group (p < 0.05).
Conclusion: Hsa_circ_0005325 is highly expressed in SCC25 and CAL-27 cells. Downregulation of hsa_circ_0005325 can inhibit the proliferation and invasion of SCC25 and CAL-27 cells and promote their apoptosis.

Aim: To investigate the phenotypic and genomic features of three multidrug-resistant (MDR) clinical mucoid and non-mucoid uropathogenic Escherichia coli (UPEC) strains to understand their antimicrobial resistance, biofilm formation, and virulence in urinary tract infections (UTIs).
Methods And Results: The UPEC strains A5, A10, and A15 were isolated from two UTI patients. Phenotypic assays included colony morphology, antibiotic susceptibility, motility, and biofilm formation.

is a thermophilic acetogenic bacterium capable of thriving at elevated temperatures up to 66°C. It metabolizes carbohydrates such as glucose, mannose, and fructose and can also grow lithotrophically utilizing hydrogen (H) and carbon dioxide (CO) or carbon monoxide (CO), with acetate serving as its main product. A simple and efficient genome editing system for would not only facilitate the understanding of the physiological function of enzymes involved in energy and carbon metabolism but also enable metabolic engineering.

Gastric cancer (GC) is the third leading cause of cancer mortality globally, often presenting with insidious symptoms that lead to late-stage diagnoses, underscoring the critical need for innovative diagnostic and therapeutic strategies. One such avenue is the exploration of ferroptosis, a regulated form of cell death implicated in various pathological conditions and malignancies. In this study, we demonstrate that brucine, an alkaloid derived from Strychnos nux-vomica, exerts significant antitumor effects on GC cells both in vitro and in vivo.

The utility of bio-reductive prodrugs in cancer research has emerged as an attractive strategy. We synthesized and characterized a couple of cobalt(iii)-Schiff base complexes of general molecular formula Co(L)(L) and Co(L)(dox) , where L and L are ,-(ethane-1,2-diyl)bis(1-(pyridine-2-yl)methanimine) and 1-phenyl-1,3-butanedione, and dox = doxorubicin, as bio-reductive prodrugs. UV-vis and fluorescence spectroscopic assays confirmed the reductive release of doxorubicin from the complex in a GSH-dependent manner under physiological conditions, showing its potential for drug release.

Challenges in cancer treatment lie in the identification and development of novel agents with potent anti-tumor activity. A series of novel dehydroabietylamine-pyrimidine derivatives 3a-3s were designed and synthesized based on the principles of molecular hybridization. The inhibitory activities of the target compounds against the proliferation of four different human cancer cell lines (HepG2, A549, HCT116 and MCF-7) were evaluated.
