KLF5 promotes cervical cancer proliferation, migration and invasion in a manner partly dependent on TNFRSF11a expression.

Although the transcription factor Krüppel-like factor 5 (KLF5) plays important roles in both inflammation and cancer, the mechanism by which this factor promotes cervical carcinogenesis remains unclear. In this study, we demonstrated a potential role for tumour necrosis factor receptor superfamily member 11a (TNFRSF11a), the corresponding gene of which is a direct binding target of KLF5, in tumour cell proliferation and invasiveness. Coexpression of KLF5 and TNFRSF11a correlated significantly with tumorigenesis in cervical tissues (P < 0.

Glutathione-bound gold nanoclusters for selective-binding and detection of glutathione S-transferase-fusion proteins from cell lysates.

A straightforward method for the rapid detection of the presence of glutathione S-transferase (GST)-tagged proteins from sample solutions using glutathione (GSH)-bound gold nanoclusters (Au@GSH NCs) with luminescence properties as the detection probes by simple observation with the naked eye was proposed in this study.

A new feasible method for fibrinogen purification based on the affinity of Staphylococcus aureus clumping factor A to fibrinogen.

Plasma fibrinogen participates in several physiological and pathological events thus becoming a useful studying material in biomedical research. Here we report a new convenient method for fibrinogen purification based on the affinity of Staphylococcus aureus clumping factor A to fibrinogen. Clumping factor A (ClfA) is a cell wall-anchored surface protein of S.

A segment of Staphylococcus aureus clumping factor A with fibrinogen-binding activity (ClfA221-550) inhibits platelet-plug formation in mice.

We previously reported that the fibrinogen-binding segment (residues 221-550) of Staphylococcus aureus clumping factor A (ClfA), which binds to fibrinogen gamma chain C-terminus, exerted inhibitory effects on platelet aggregation and fibrin clot formation in vitro. Here, we further demonstrated the effectiveness of using ClfA221-550 to inhibit platelet-rich thrombus formation in vivo. Platelet-rich thrombi were formed in the mesenteric venules of fluorescein-loaded mice by filtered light illumination.
