That is, in the same image of a genetically identical population, individual cells can have different protein localization patterns (Fig. 2). This makes the data weakly labeled and the classification task weakly supervised. To evaluate the performance of the participating models, a test dataset of...
The tumor microenvironment (TME) in pancreatic ductal adenocarcinoma (PDAC) is a complex ecosystem that drives tumor progression; however, in-depth single cell characterization of the PDAC TME and its role in response to therapy is lacking. Here, we perf
The organic element of the bone matrix is primarily collagen, a fibrous protein that gives bone flexibility and tensile strength [10]. Collagen makes up a large portion of the organic matrix, accounting for approximately 85 to 90% of the organic matrix of bone [11]. Figure 1. Distribution ...
Overall, we identified 1380 transcripts that were differentially expressed (p< 0.05) between progressive and non-progressive ccRCC samples. Of these, 639 were protein-coding genes; 217 were downregulated and 422 upregulated in progressive compared with non-progressive cases. A heat map based on the...
Technology that enables transfer of miniature ‘islands’ of extracellular matrix proteins to enforce control of the shape and size of adherent cells either as single cells or cell colonies. Stemness The characteristic of a cell that makes it a stem cell. That is, the ability to self-renew an...
纤毛器作为染色体上的特定区域,与着丝粒的附着密切相关,并在细胞周期中经历显著的变化。然而,目前对衰老过程中染色体重塑的了解仍然有限,特别是染色体着丝粒的变化机制尚需深入探讨。 染色体着丝粒是人类染色体上独特的染色质结构,包含串联排列的171个碱基对的富含AT的α卫星DNA【2】。大多数染色体 (除人类Y染色体外) 在...
This inefficiency makes the process of CLG both time consuming and laborious. Currently, there are two main CHO expression systems, dihydrofolate reductase (DHFR)-based methotrexate (MTX) selection and glutamine synthetase (GS)-based methionine sulfoximine (MSX) selection, that have been in wide ...
38, 39 The fact that both groups exhibit amyloid deposits with these subtle differences suggests that the presence of AChE in the amyloid plaques makes the difference. AChE Accelerates Aggregation of Rat Aβ The fact that 8 weeks later the animals injected with Aβ-AChE complexes showed an ...
In the presence of oxygen, HIF-1α is modified by prolyl hydroxylases, which target it to a ubiquitin ligase complex that includes the tumor suppressor VHL. This association results in constitutive normoxic degradation of the HIF-1α protein. Hypoxia, mutation of VHL, or accumulation of ...
