Metabolism and signalling are tightly coupled in bacteria. Combining several theoretical approaches, a core model is presented that describes transcriptional and allosteric control of glycolysis in Escherichia coli. Experimental data based on microarrays, signalling components and extracellular metabolites are used to estimate kinetic parameters. A newly designed strain was used that adjusts the incoming glucose flux into the system and allows a kinetic analysis. Based on the results, prediction for intracelluar metabolite concentrations over a broad range of the growth rate could be performed and compared with data from literature.

miR-9-5p/HMMR regulates the tumorigenesis and progression of clear cell renal cell carcinoma through EMT and JAK1/STAT1 signaling pathway.
J Transl Med
January 2025
Department of Urology, The First Affiliated Hospital, Zhejiang University School of Medicine, Qingchun Road 79, Hangzhou, Zhejiang, 310003, China.
Background: The most common malignant type of kidney cancer is clear cell renal cell carcinoma (ccRCC). The expression levels of hyaluronan-mediated motility receptor (HMMR) in many tumor types are significantly elevated. HMMR is closely associated with tumor-related progression, treatment resistance, and poor prognosis, and has yet to be fully investigated in terms of its expression patterns and molecular mechanisms of action in ccRCC.

Background: A novel anti-human epidermal growth factor receptor 2 (HER2) antibody-drug conjugate (ADC) GQ1001 was assessed in patients with previously treated HER2 positive advanced solid tumors in a global multi-center phase Ia dose escalation trial.
Methods: In this phase Ia trial, a modified 3 + 3 study design was adopted during dose escalation phase. Eligible patients were enrolled, and GQ1001 monotherapy was administered intravenously every 3 weeks.
The experiences of organizational silence among nurses: a qualitative meta-synthesis.
BMC Nurs
January 2025
Nursing Department, School of Medicine, Shanghai Tenth People's Hospital, Tongji University, Shanghai, 200072, China.
Objective: A growing body of research shows that the organizational silence among nurses not only affects their job satisfaction and performance but also exacerbates their intention to leave their jobs, posing a threat to the long-term stability of the nursing team. Therefore, the aim of this study was to synthesize existing qualitative research to explore the real experiences of nurses' organizational silence behavior and gain insight into the motivations and feelings behind it.

BMC Med Ethics
January 2025
Department of Obstetrics, Gynaecology and Women's Health, University of Otago, Wellington, Aotearoa, New Zealand.
Background: Being able to measure informed choice represents a mechanism for service evaluation to monitor whether informed choice is achieved in practice. Approaches to measuring informed choice to date have been based in the biomedical hegemony. Overlooked is the effect of epistemic positioning, that is, how people are positioned as credible knowers in relation to knowledge tested as being relevant for informed choice.
