Abstract

The renowned proverb that "The pen is mightier than the sword" underscores the formidable influence wielded by text expressions in shaping sentiments. Indeed, well-crafted written can deeply resonate within cultures, conveying profound sentiments. Nowadays, the omnipresence of the Internet has fostered a subculture that congregates around the contemporary milieu. The subculture artfully articulates the intricacies of human feelings by ardently pursuing the allure of novelty, a fact that cannot be disregarded in the sentiment analysis. This paper strives to enrich data through the lens of subculture, to address the insufficient training data faced by sentiment analysis. To this end, a new approach of subculture-based data augmentation (SCDA) is proposed, which engenders six enhanced texts for each training text by leveraging the creation of six diverse subculture expression generators. The extensive experiments attest to the effectiveness and potential of SCDA. The results also shed light on the phenomenon that disparate subculture expressions elicit varying degrees of sentiment stimulation. Moreover, an intriguing conjecture arises, suggesting the linear reversibility of certain subculture expressions. It is our fervent aspiration that this study serves as a catalyst in fostering heightened perceptiveness towards the tapestry of information, sentiment and culture, thereby enriching our collective understanding., Comment: JASIST

Abstract

Objective To analyze the biological processes regulated by protein kinase WNK2 in ovarian cancer cells based on protein phosphorylation modified mass spectrometry. Methods Ovarian cancer cell line SKOV3 was transfected with lentiviral vector to knockdown WNK2 and the obtained cells were further screened by drug screening. Then the total protein was extracted for protein phosphorylation modification mass spectrometry analysis. Bioinformatics analysis was adopted to detect the phosphorylation changes before and after WNK2 knockdown, and differential proteins were screened out. Gene Ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis were employed to explore the functions of differentially phosphorylated proteins, and experiments were performed to verify the biological processes regulated by WNK2. Results Phosphorylation modified mass spectrometry indicated that WNK2 knockdown significantly decreased the phosphorylation of 745 proteins with 1 078 altered protein sites, and increased the phosphorylation of 328 proteins with 415 altered protein sites. KEGG and GO enrichment analyses showed WNK2 influences biological processes such as cytoskeleton organization, signal transduction, cell composition, and regulation of kinase activity. Phalloidin staining indicated after WNK2 knockdown resulted in broken and disordered cytoskeleton, while its overexpression promoted cytoskeleton remodeling. Conclusion WNK2 is involved in the cytoskeleton formation in ovarian cancer cells by regulating the phosphorylation of vimentin and other proteins.

Abstract

Nowadays, the omnipresence of the Internet has fostered a subculture that congregates around the contemporary milieu. The subculture artfully articulates the intricacies of human feelings by ardently pursuing the allure of novelty, a fact that cannot be disregarded in the sentiment analysis. This paper aims to enrich data through the lens of subculture, to address the insufficient training data faced by sentiment analysis. To this end, a new approach of subculture‐based data augmentation (SCDA) is proposed, which engenders enhanced texts for each training text by leveraging the creation of specific subcultural expression generators. The extensive experiments attest to the effectiveness and potential of SCDA. The results also shed light on the phenomenon that disparate subcultural expressions elicit varying degrees of sentiment stimulation. Moreover, an intriguing conjecture arises, suggesting the linear reversibility of certain subcultural expressions. [ABSTRACT FROM AUTHOR]
