Efficacy of imeglimin in patients with type 2 diabetes mellitus complicated by metabolic dysfunction-associated steatotic liver disease: A multicentre study.

Aims: This study aimed to evaluate the effectiveness of imeglimin in improving liver function and fibrosis in patients with type 2 diabetes (T2D) complicated by metabolic dysfunction-associated steatotic liver disease (MASLD).

Materials And Methods: We conducted a multicentre study involving 80 patients with T2D and MASLD who were treated with or without imeglimin for 24 weeks. We assessed the changes in diabetes-related parameters, including HbA1c, fasting blood glucose, glycoalbumin and C-peptide index.

NMDA Suppresses Pancreatic ABCA1 Expression through the MEK/ERK/LXR Pathway in Pancreatic Beta Cells.

Dysfunction or loss of pancreatic β cells can cause insulin deficiency and impaired glucose regulation, resulting in conditions like type 2 diabetes. The ATP-binding cassette transporter A1 (ABCA1) plays a key role in the reverse cholesterol transport system, and its decreased expression is associated with pancreatic β cell lipotoxicity, resulting in abnormal insulin synthesis and secretion. Increased glutamate release can cause glucotoxicity in β cells, though the detailed mechanisms remain unclear.

gen. nov., sp. nov., an anaerobic, obligately syntrophic archaeon, the first isolate of the lineage 'Asgard' archaea, and proposal of the new archaeal phylum phyl. nov. and kingdom regn. nov.

An anaerobic, mesophilic, syntrophic, archaeon strain MK-D1, was isolated as a pure co-culture with sp. strain MK-MG from deep-sea methane seep sediment. This organism is, to our knowledge, the first cultured representative of 'Asgard' archaea, an archaeal group closely related to eukaryotes.

A Marine Group A isolate relies on other growing bacteria for cell wall formation.

Most of Earth's prokaryotes live under energy limitation, yet the full breadth of strategies that enable survival under such conditions remain poorly understood. Here we report the isolation of a bacterial strain, IA91, belonging to the candidate phylum Marine Group A (SAR406 or 'Candidatus Marinimicrobia') that is unable to synthesize the central cell wall compound peptidoglycan itself. Using cultivation experiments and microscopy, we show that IA91 growth and cell shape depend on other bacteria, deriving peptidoglycan, energy and carbon from exogenous muropeptide cell wall fragments released from growing bacteria.
