Abstract
Background: Hepatocellular carcinoma (HCC) is one of the most common causes of cancer‐related mortality worldwide. Early detection of HCC can significantly improve patients' outcomes. An increasing number of studies have validated that Homer is dysregulated in cancers and may serve as diagnostic markers. In the present study, we investigated the expression profile and diagnostic significance of Homer2 and Homer3 in hepatitis B virus-induced HCC (HBV-HCC). Methods: Quantitative real-time PCR (QRT-PCR), western blot analysis and immunohistochemistry analysis. Results: Homer2 and Homer3 were downregulated in HCC. The expression of Homer2 was associated with tumor differentiation grade (P= 0.012) and total protein (TP) level (P= 0.032). Homer3 was related to tumor size (P= 0.010), tumor nodes (P= 0.026) and γ-glutamyl transferase (GGT) level (P= 0.001). The receiver operating characteristic curve analyses indicated that the combination of Homer2, Homer3 and AFP possessed a high accuracy (AUC=0.900) to diagnose HCC cases from healthy controls. Conclusion: Our data indicated that Homer2 and Homer3 were downregulated in HCC and might be potential diagnostic marker for HCC.

Abstract
When administered as a single subanesthetic dose, the N-methyl-D-aspartate (NMDA) receptor antagonist, ketamine, produces rapid (within hours) and relatively sustained antidepressant actions even in treatment-resistant patients. Preclinical studies have shown that ketamine increases dendritic spine density and synaptic proteins in brain areas critical for the actions of antidepressants, yet the temporal relationship between structural changes and the onset of antidepressant action remains poorly understood. In this study, we examined the effects of a single dose of S-ketamine (15 mg/kg) on dendritic length, dendritic arborization, spine density, and spine morphology in the Flinders Sensitive and Flinders Resistant Line (FSL/FRL) rat model of depression. We found that already 1 h after injection with ketamine, apical dendritic spine deficits in CA1 pyramidal neurons of FSL rats were completely restored. Notably, the observed increase in spine density was attributable to regulation of both mushroom and long-thin spines. In contrast, ketamine had no effect on dendritic spine density in FRL rats. On the molecular level, ketamine normalized elevated levels of phospho-cofilin and the NMDA receptor subunits GluN2A and GluN2B and reversed homer3 deficiency in hippocampal synaptosomes of FSL rats. Taken together, our data suggest that rapid formation of new spines may provide an important structural substrate during the initial phase of ketamine's antidepressant action.
