Molecular Cancer volume 22 , Article number: Cite this article. Metrics details. The treatment of Triple-negative breast cancer TNBC has always been challenging due to its heterogeneity and the absence of well-defined molecular targets. To identify the polypeptide-coding function of circCAPG, a series of experiments, such as Mass spectrometry and dual-luciferase reporter assays were conducted. Cell proliferation, apoptosis and metastasis parameters were determined to investigate the cancerous functions CAPGaa plays in both TNBC organoids and nude mice. TNBC is characterized by deficient expression of estrogen receptor ER , progesterone receptor PR and human epidermal growth factor receptor type 2 Her-2 [ 3 ]. Therefore, unlike the hormone receptor-positive and Herpositive subtypes, TNBC still lacks valid clinical biomarkers and therapeutic strategies [ 4 ]. The effort to screen out reliable drug targets to improve the prognosis of TNBC patients is urgent. Thus, circRNAs are more stable than their linear counterparts. Amount of studies have demonstrated that circRNAs can be detected in plasma, saliva, and exosomes [ 5 , 6 , 7 , 8 ]. For example, Ju et al. All these provide strong support for the practice of circRNAs as biomarkers or therapeutic targets in clinical treatment.

Tock M. Perhaps such a conformation is a transient high-energy state that could not be captured in the structure. Małgorzata FigielMałgorzata Figiel.

The authors wish it to be known that, in their opinion, the first two authors should be regarded as Joint First Authors. Abortive infection Abi is a bacterial antiphage defense strategy involving suicide of the infected cell. Some Abi pathways involve polymerases that are related to reverse transcriptases. They are unique in the way they combine the ability to synthesize DNA in a template-independent manner with protein priming. Here, we report crystal and cryo-electron microscopy structures of two Abi polymerases: AbiK and Abi-P2. Both proteins adopt a bilobal structure with an RT-like domain that comprises palm and fingers subdomains and a unique helical domain. AbiK and Abi-P2 adopt a hexameric and trimeric configuration, respectively, which is unprecedented for reverse transcriptases.

Ti-plasmid, short for tumour-inducing plasmid, is an extrachromosomal molecule of DNA found commonly in the plant pathogen Agrobacterium tumefaciens. It is also found in other species of Agrobacterium such as A. Agrobacterium is a gram negative bacteria that belongs to the class Alphaproteobacteria. It is one of the pathogenic species belonging to this class. Other non-pathogenic and plant symbiotic species include Caulobacter , Rhodobacter and Rhizobium. The Ti-plasmid in the bacteria is known to induce crown gall disease in plants by transferring crucial regions from the plasmid. These crucial regions were seen to modify the plant cells into a tumour to produce synthetic plant hormones and cause crown gall. This led the scientists to believe that there is a scope for bioengineering techniques to modify the plants using Ti-plasmid for our own use. Ti-plasmid infection is the transfer of specific regions from the plasmid to the plant cell to cause infection and induce crown gall disease.

Federal government websites often end in. The site is secure. Preview improvements coming to the PMC website in October Learn More or Try it out now. Agrobacterium tumefaciens is a plant pathogen with the capacity to deliver a segment of oncogenic DNA carried on a large plasmid called the tumor-inducing or Ti plasmid to susceptible plant cells. These large replicons typically code for functions essential for cell physiology, pathogenesis, or symbiosis. Most of these elements rely on a conserved gene cassette termed repABC for replication and partitioning, and maintenance at only one or a few copies per cell 1. We will summarize the features of this plasmid as a representative of the repABC family of megaplasmids. We will also describe novel features of this plasmid that enable A. At the end of this chapter, we will describe how this natural genetic engineer has been adapted to spawn an entire industry of plant biotechnology and review its potential for use in future therapeutic applications of plant and nonplant species.

The structure and mechanism of RT-related abortive infection proteins were previously unknown. Nucleic Acids Res. These bombed cells are being grown. Comparison of this map with the crystallographic model allowed for the precise pixel size calibration. The polymerase domain is shown in red for palm and blue for fingers, the helical domain is shown in yellow, and DNA is shown in black. They have very diverse activities and thus are assumed to trigger cell death through different mechanisms. Source: Chris Winters, www. Abi-P2 was diluted in 20 mM Tris pH 7.
