Effective protective mechanisms of HO-1 in diabetic complications: a narrative review.

Diabetes mellitus is a metabolic disorder with persistent hyperglycemia caused by a variety of underlying factors. Chronic hyperglycemia can lead to diverse serious consequences and diversified complications, which pose a serious threat to patients. Among the major complications are cardiovascular disease, kidney disease, diabetic foot ulcers, diabetic retinopathy, and neurological disorders.

Near infrared aggregation-induced emission fluorescent materials for lipid droplets testing and photodynamic therapy.

Near-infrared (NIR) fluorescent probes with aggregation-induced emission (AIE) properties are of great significance in cell imaging and cancer therapy. However, the complexity of its synthesis, poor photostabilities, and expensive raw materials still pose some obstacles to their practical application. This study reported an AIE luminescent material with red emission and its application in in vitro imaging and photodynamic therapy (PDT) study.

Dapagliflozin prevents kidney podocytes pyroptosis via miR-155-5p/HO-1/NLRP3 axis modulation.

Diabetic nephropathy (DN) is a significant clinical microvascular complication associated with diabetes mellitus (DM), and end-stage diabetes giving rise to kidney failure is developing into the major etiological factor of chronic kidney failure. Dapagliflozin is reported to limit podocyte damage in DM, which has proven to protect against renal failure. Mounting evidence has demonstrated that pyroptosis is associated with DM progression.

Dapagliflozin alleviates renal podocyte pyroptosis via regulation of the HO‑1/NLRP3 axis.

Diabetic nephropathy is one of the most significant complications of diabetes, resulting in increased patient mortality. Dapagliflozin is an inhibitor of sodium‑glucose cotransporter 2 that has an important protective effect on the kidney. Recent studies showed that pyroptosis is involved in the advancement of diabetic nephropathy (DN).

Role of transcription factor FOXM1 in diabetes and its complications (Review).

Diabetes mellitus is a chronic metabolic disease commonly associated with complications such as cardiovascular disease, nephropathy and neuropathy, the incidence of which is increasing yearly. Transcription factor forkhead box M1 (FOXM1) serves an important role in development of diabetes and its complications. The present study aimed to review the association between FOXM1 with pathogenesis of diabetes and its complications.

Design of small monomeric and highly bright near-infrared fluorescent proteins.

Due to the low absorbance in the far-red (FR) and near-infrared (NIR) "optical window", NIR fluorescent proteins (FPs) are powerful tools for deep imaging. Here, we report three new, highly bright NIR FPs termed BDFP1.8, BDFP1.

A Large Stokes Shift Fluorescent Protein Constructed from the Fusion of Red Fluorescent mCherry and Far-Red Fluorescent BDFP1.6.

Phycobiliproteins are constituents of phycobilisomes that can harvest orange, red, and far-red light for photosynthesis in cyanobacteria and red algae. Phycobiliproteins in the phycobilisome cores, such as allophycocyanins, absorb far-red light to funnel energy to the reaction centers. Therefore, allophycocyanin subunits have been engineered as far-red fluorescent proteins, such as BDFP1.

Chromophorylation (in Escherichia coli) of allophycocyanin B subunits from far-red light acclimated Chroococcidiopsis thermalis sp. PCC7203.

Cyanobacterial phycobilisomes funnel the harvested light energy to the reaction centers via two terminal emitters, allophycocyanin B and the core-membrane linker. ApcD is the α-subunit of allophycocyanin B responsible for its red-shifted absorbance (λ 665 nm). Far-red photo-acclimated cyanobacteria contain certain allophycocyanins that show even further red-shifted absorbances (λ > 700 nm).

A Simple Preparation Method for Phytochromobilin.

Phytochromobilin (PΦB), the chromophore of plant phytochromes, is difficult to isolate because phytochromes occur at very low concentrations in plants. It is, therefore, frequently replaced in plant phytochrome studies by phycocyanobilin, which is abundant in cyanobacteria. PΦB is also an attractive chromophore for far-red emitting chromoproteins.

Adapting photosynthesis to the near-infrared: non-covalent binding of phycocyanobilin provides an extreme spectral red-shift to phycobilisome core-membrane linker from Synechococcus sp. PCC7335.

Phycobiliproteins that bind bilins are organized as light-harvesting complexes, phycobilisomes, in cyanobacteria and red algae. The harvested light energy is funneled to reaction centers via two energy traps, allophycocyanin B and the core-membrane linker, ApcE1 (conventional ApcE). The covalently bound phycocyanobilin (PCB) of ApcE1 absorbs near 660 nm and fluoresces near 675 nm.
