Point mutations in functionally diverse genes are associated with increased natural DNA transformation in multidrug resistant Streptococcus pneumoniae.

DNA transformation is key for phenotypic diversity and adaptation of Streptococcus pneumoniae including in the emergence of multidrug resistance (MDR). Under laboratory conditions, DNA transformation is facilitated by the artificial triggering of competence by the competence stimulating peptide (CSP). In ongoing DNA transformation work, we observed that exogenous CSP was dispensable depending on the combination of strains and culture media.

The role of Imp and Syp RNA-binding proteins in precise neuronal elimination by apoptosis through the regulation of transcription factors.

Neuronal stem cells generate a limited and consistent number of neuronal progenies, each possessing distinct morphologies and functions, which are crucial for optimal brain function. Our study focused on a neuroblast (NB) lineage in known as Lin A/15, which generates motoneurons (MNs) and glia. Intriguingly, Lin A/15 NB dedicates 40% of its time to producing immature MNs (iMNs) that are subsequently eliminated through apoptosis.

Water fluxes pattern growth and identity in shoot meristems.

In multicellular organisms, tissue outgrowth creates a new water sink, modifying local hydraulic patterns. Although water fluxes are often considered passive by-products of development, their contribution to morphogenesis remains largely unexplored. Here, we mapped cell volumetric growth across the shoot apex in Arabidopsis thaliana.

Holistic understanding of trimethoprim resistance in using an integrative approach of genome-wide association study, resistance reconstruction, and machine learning.

Unlabelled: Antimicrobial resistance (AMR) is a public health threat worldwide. Next-generation sequencing (NGS) has opened unprecedented opportunities to accelerate AMR mechanism discovery and diagnostics. Here, we present an integrative approach to investigate trimethoprim (TMP) resistance in the key pathogen .

Transcriptional Induction of and Fibrinolysis Inhibition as Predominant Effects of Glucocorticoids on the Cancer Coagulome.

Background/aim: How tumors regulate the genes of the coagulome is crucial for cancer-associated thrombosis and the occurrence of venous thromboembolic complications in patients with cancer. We have previously reported potent yet complex effects of glucocorticoids (GC) on the expression of three genes that play a key role in the regulation of thrombin/plasmin activation (F3, PLAU, and SERPINE1). This study aimed to extend the investigation of GC effects to the whole tumor coagulome and assess the resulting impact on the ability of cancer cells to activate thrombin and plasmin.
