Oxidative lipid damage by naringenin selectively sensitizes chronic myeloid leukemia cell lines and patient samples to Bcr-Abl tyrosine kinase inhibitors.

Chronic myeloid leukemia (CML) treatment with Bcr-Abl tyrosine kinase inhibitors (TKIs) has significantly improved patient outcomes, yet challenges such as drug resistance and persistence of leukemic stem cells persist. This study explores the potential of naringenin, a natural flavonoid, to enhance the efficacy of Bcr-Abl TKIs in CML therapy. We showed that naringenin reduces viability of a panel of CML cell lines regardless of varying cellular origin and genetic mutations, and acts synergistically with dasatinib and ponatinib.

Synaptic cell adhesion molecules contribute to the pathogenesis and progression of fragile X syndrome.

Fragile X syndrome (FXS) is the most common form of inherited intellectual disability and a monogenic cause of autism spectrum disorders. Deficiencies in the fragile X messenger ribonucleoprotein, encoded by the gene, lead to various anatomical and pathophysiological abnormalities and behavioral deficits, such as spine dysmorphogenesis and learning and memory impairments. Synaptic cell adhesion molecules (CAMs) play crucial roles in synapse formation and neural signal transmission by promoting the formation of new synaptic contacts, accurately organizing presynaptic and postsynaptic protein complexes, and ensuring the accuracy of signal transmission.

Activation of the NLRP3 inflammasome was measured in blood samples, as well as pain levels and clinical markers. Neuropathic pain patients exhibited elevated NLRP3 inflammasome activation.

Brain region-specific roles of brain-derived neurotrophic factor in social stress-induced depressive-like behavior.

Brain-derived neurotrophic factor is a key factor in stress adaptation and avoidance of a social stress behavioral response. Recent studies have shown that brain-derived neurotrophic factor expression in stressed mice is brain region-specific, particularly involving the corticolimbic system, including the ventral tegmental area, nucleus accumbens, prefrontal cortex, amygdala, and hippocampus. Determining how brain-derived neurotrophic factor participates in stress processing in different brain regions will deepen our understanding of social stress psychopathology.

China Initiative for Multi-Domain Intervention (CHINA-IN-MUDI) to Prevent Cognitive Decline: Study Design and Progress.

Background: Alzheimer's disease (AD), the most common type of irreversible dementia, is predicted to affect 152 million people by 2050. Evidence from large-scale preventive randomized controlled trials (RCTs) on modifiable risk variables in Europe has shown that multi-domain lifestyle treatments for older persons at high risk of dementia may be practical and effective. Given the substantial differences between the Chinese and European populations in terms of demographics and living conditions, direct adoption of the European program in China remains unfeasible.

The potential role of ribonucleic acid methylation in the pathological mechanisms of fragile X syndrome.

Fragile X syndrome (FXS) is a common inherited cause of intellectual disabilities and single-gene cause of autism spectrum disorder (ASD), resulting from the loss of functional fragile X messenger ribonucleoprotein (FMRP), an RNA-binding protein (RBP) encoded by the fragile X messenger ribonucleoprotein 1 (FMR1) gene. Ribonucleic acid (RNA) methylation can lead to developmental diseases, including FXS, through various mechanisms mediated by 5-hydroxymethylcytosine, 5-methylcytosine, N-methyladenosine, etc. Emerging evidence suggests that modifications of some RNA species have been linked to FXS.
