The Asian citrus psyllid, Diaphorina citri Kuwayama (Hemiptera: Liviidae), is a major pest of global citriculture. In the Americas and in Asia, D. citri vectors the phloem-limited bacterium, Candidatus Liberibacter asiaticus (CLas), which causes the fatal citrus disease huanglongbing, or citrus greening. Cell lines derived from D. citri can provide insight into both the basic biology of this pest and D. citri-associated pathogens including CLas. We previously identified CLG#2 as the optimal medium for long-term growth of D. citri primary cell cultures. Here we report on the establishment and characterization of three continuous D. citri cell lines, Dici1, Dici3, and Dici5, that have been passaged for > 40 times. Based on morphological and transcriptomic data, the Dici1 and Dici3 cell lines include undifferentiated and neurogenic progenitor cells. Dici1 and Dici5 are infected with Wolbachia. Both Dici1 and Dici5 are infected with D. citri reovirus, and Dici5 is also infected with D. citri-associated C virus. Dici3 is free of both Wolbachia and virus infection. These cell lines provide an ideal platform for the study of inter-microbial relationships as well as microbe interaction with host insect cells.

Upregulation of Cyclin E1 and subsequent activation of CDK2 accelerates cell cycle progression from G1 to S phase and is a common oncogenic driver in gynecological malignancies. WEE1 kinase counteracts the effects of Cyclin E1/CDK2 activation by regulating multiple cell cycle checkpoints. Here we characterized the relationship between Cyclin E1/CDK2 activation and sensitivity to the selective WEE1 inhibitor azenosertib.

Cholangiocarcinoma (CCA), a highly aggressive form of cancer, is known for its high mortality rate. A Disintegrin and Metalloprotease Domain-like Protein Decysin-1 (ADAMDEC1) can promote the development and metastasis in various tumors by degrading the extracellular matrix. However, its regulatory mechanism in CCA remains unclear.

Multiple myeloma(MM) remains incurable with high relapse and chemoresistance rates. Differentially expressed genes(DEGs) between newly diagnosed myeloma and secondary plasma cell leukemia(sPCL) were subjected to a weighted gene co-expression network analysis(WGCNA). Drug resistant myeloma cell lines were established.

Prostate cancer is a disease which poses an interesting clinical question: Should it be treated? Only a small subset of prostate cancers are aggressive and require removal and treatment to prevent metastatic spread. However, conventional diagnostics remain challenged to risk-stratify such patients; hence, new methods of approach to biomolecularly sub-classify the disease are needed. Here we use an unsupervised self-organising map approach to analyse live-cell Raman spectroscopy data obtained from prostate cell-lines; our aim is to exemplify this method to sub-stratify, at the single-cell-level, the cancer disease state using high-dimensional datasets with minimal preprocessing.

Spatial protein expression technologies can map cellular content and organization by simultaneously quantifying the expression of >40 proteins at subcellular resolution within intact tissue sections and cell lines. However, necessary image segmentation to single cells is challenging and error prone, easily confounding the interpretation of cellular phenotypes and cell clusters. To address these limitations, we present STARLING, a probabilistic machine learning model designed to quantify cell populations from spatial protein expression data while accounting for segmentation errors.
