Regulation of podocyte survival and endoplasmic reticulum stress by fatty acids and its modification by Stearoyl-CoA desaturases and cyclic AMP [PDF]

, 2011
Podocyte apoptosis is a hallmark in the development and progression of diabetic nephropathy (DN). Several factors of the diabetic milieu are known to induce podocyte apoptosis. Currently, the role of free fatty acids (FFAs) for podocytopathy and podocyte

A Prostacyclin Analog Prevents Radiocontrast Nephropathy via Phosphorylation of Cyclic AMP Response Element Binding Protein [PDF]

The American Journal of Pathology, 2005
We reported previously that radiocontrast medium induces caspase-dependent apoptosis and that cAMP analogs inhibit cell injury in cultured renal tubular cells. In the present study, cellular mechanisms underlying the protective effects of cAMP were determined.

Dual‐Peptide Nanoplatform: Mesoporous Silica Nanoparticles Functionalized With a Cell‐Penetrating Peptide and Loaded With Rationally Designed Antimicrobial Peptides for Tuberculosis Therapy

Advanced Healthcare Materials, EarlyView.
Machine learning–guided engineering of a plectasin‐derived peptide yields DC05, a potent antimycobacterial candidate. Encapsulation into tuftsin‐functionalized mesoporous silica nanoparticles enhances intracellular delivery, stability, and activity against Mycobacterium tuberculosis while maintaining low cytotoxicity and minimal hemolysis. The combined

Mutant huntingtin impairs PNKP and ATXN3, disrupting DNA repair and transcription

eLife, 2019
How huntingtin (HTT) triggers neurotoxicity in Huntington’s disease (HD) remains unclear. We report that HTT forms a transcription-coupled DNA repair (TCR) complex with RNA polymerase II subunit A (POLR2A), ataxin-3, the DNA repair enzyme polynucleotide ...

Nanotherapies for Atherosclerosis: Targeting, Catalysis, and Energy Transduction

Advanced Healthcare Materials, EarlyView.
Atherosclerosis management is hindered by poor drug targeting and plaque heterogeneity. Nanotechnology overcomes these barriers via three core strategies: (1) target‐engineered nanocarriers that achieve lesion‐specific precision via ligand modification, biomimetic camouflage, stimuli‐responsive release, and self‐propelling nanomotors; (2) catalytic ...

PSD-95 in the anterior cingulate cortex contributes to neuropathic pain by interdependent activation with NR2B

Scientific Reports, 2022
Studies suggest that the scaffolding protein, postsynaptic density protein-95 (PSD-95), is involved in multiple neurological dysfunctions. However, the role of PSD-95 in the anterior cingulate cortex (ACC) in neuropathic pain (NP) has not been ...

Asynchronous Rhythm of Steroidogenic Factor 1 and Period Homolog 2 mRNA Expression in Mouse Y1 Adrenocorticol Tumor Cells [PDF]

, 2010
The relationship between the expression of Steroidogenic factor 1 (Sf1) and the circadian-related gene, period homolog 2 (Per2), in the adrenal cortex is still unknown.

Looking downstream: the role of cyclic AMP-regulated genes in axonal regeneration [PDF]

, 2015
Elevation of intracellular cyclic AMP (cAMP) levels has proven to be one of the most effective means of overcoming inhibition of axonal regeneration by myelin-associated inhibitors such as myelin-associated glycoprotein, Nogo, and oligodendrocyte myelin ...

DNA Replication Stress-induced Phosphorylation of Cyclic AMP Response Element-binding Protein Mediated by ATM [PDF]

Journal of Biological Chemistry, 2006
The DNA damage-response regulators ATM (ataxia-telangiectasia-mutated) and ATR (ATM-Rad3-related) are structurally and functionally related protein kinases that exhibit nearly identical substrate specificities in vitro. Current paradigms hold that the relative contributions of ATM and ATR to nuclear substrate phosphorylation are dictated by the type of

Opinion: Gavage Administration of MXene as a Route‐Specific Alternative to Intravenous Injection into the Bloodstream of Laboratory Animals for Reducing Systemic Nanotoxicity Risks in Immunosuppression and Post‐Transplantation Models with Bile Acid Modification

Advanced Healthcare Materials, EarlyView.
Recent studies reported immunosuppressive properties of specific MXene nanomaterials. Their intravenous injection into the bloodstream of laboratory animals has been a common delivery method to suppress systemic inflammation and prevent transplant rejection.
