Pan-neuronal expression of human mutant SOD1 in Drosophila impairs survival and motor performance, induces early neuroinflammation and chromosome aberrations
Biochim Biophys Acta Mol Basis Dis. 2024 Apr 22:167192. doi: 10.1016/j.bbadis.2024.167192. Online ahead of print.ABSTRACTSeveral mutations in the SOD1 gene encoding for the antioxidant enzyme Superoxide Dismutase 1, are associated with amyotrophic lateral sclerosis, a rare and devastating disease characterized by motor neuron degeneration and patients' death within 2-5 years from diagnosis. Motor neuron loss and related symptomatology manifest mostly in adult life and, to date, there is still a gap of knowledge on the precise cellular and molecular events preceding neurodegeneration. To deepen our awareness of the early ph...

MTH1 inhibition synergizes with ROS-inducing agents to trigger cervical cancer cells undergoing parthanatos
Biochim Biophys Acta Mol Basis Dis. 2024 Apr 22:167190. doi: 10.1016/j.bbadis.2024.167190. Online ahead of print.ABSTRACTCervical cancer cells possess high levels of reactive oxygen species (ROS); thus, increasing oxidative stress above the toxicity threshold to induce cell death is a promising chemotherapeutic strategy. However, the underlying mechanisms of cell death are elusive, and efficacy and toxicity issues remain. Within DNA, 8-oxo-7,8-dihydroguanine (8-oxoG) is the most frequent base lesion repaired by 8-oxoguanine glycosylase 1 (OGG1)-initiated base excision repair. Cancer cells also express high levels of MutT h...

Hif-1 α expression targets the TMA/Fmo3/TMAO axis to participate in gallbladder cholesterol stone formation in individuals living in plateau regions
Biochim Biophys Acta Mol Basis Dis. 2024 Apr 22:167188. doi: 10.1016/j.bbadis.2024.167188. Online ahead of print.ABSTRACTThe incidence of gallbladder cholesterol stones (GCS) increases rapidly among people living in high-altitude hypoxic environments compared to those in normoxic areas. Upregulation of hepatic hypoxia inducible factor 1α (Hif-1α) plays a key role in the formation of GCS. High plasma trimethylamine-N-oxide (TMAO) levels are positively correlated with the occurrence of GCS. We hypothesized that HIF-1α may upregulate TMAO levels by promoting the transcription of flavin-containing monooxygenase 3 (Fmo3), wh...

Exercised-enriched blood plasma rescues hippocampal impairments and cognitive deficits in an Alzheimer's disease model
Biochim Biophys Acta Mol Basis Dis. 2024 Apr 21:167197. doi: 10.1016/j.bbadis.2024.167197. Online ahead of print.ABSTRACTAlzheimer's disease (AD) is a progressive neurodegenerative disorder, and moderate exercise holds promise in ameliorating the ongoing neurodegeneration and cognitive decline. Here, we investigated whether exercise-enriched blood plasm could yield a beneficial therapeutic effect on AD pathologies and cognitive decline in transgenic AD (P301S) mice. In this investigation, a cohort of 2-month-old C57BL/6 mice were granted continuous access to either a running wheel or a fixed wheel for 6 weeks. After that, ...

miR-519a-3p, found to regulate cellular prion protein during Alzheimer's disease pathogenesis, as a biomarker of asymptomatic stages
Biochim Biophys Acta Mol Basis Dis. 2024 Apr 21;1870(5):167187. doi: 10.1016/j.bbadis.2024.167187. Online ahead of print.ABSTRACTClinical relevance of miRNAs as biomarkers is growing due to their stability and detection in biofluids. In this, diagnosis at asymptomatic stages of Alzheimer's disease (AD) remains a challenge since it can only be made at autopsy according to Braak NFT staging. Achieving the objective of detecting AD at early stages would allow possible therapies to be addressed before the onset of cognitive impairment. Many studies have determined that the expression pattern of some miRNAs is dysregulated in A...

Calcium signaling induces partial EMT and renal fibrosis in a Wnt4 < sup > mCherry < /sup > knock-in mouse model
Biochim Biophys Acta Mol Basis Dis. 2024 Apr 21:167180. doi: 10.1016/j.bbadis.2024.167180. Online ahead of print.ABSTRACTThe renal tubular epithelial cells (TEC) have a strong capacity for repair after acute injury, but when this mechanism becomes uncontrollable, it leads to chronic kidney diseases (CKD). Indeed, in progress toward CKDs, the TECs may dedifferentiate, undergo epithelial-to-mesenchyme transition (EMT), and promote inflammation and fibrosis. Given the critical role of Wnt4 signaling in kidney ontogenesis, we addressed whether changes in this signaling are connected to renal inflammation and fibrosis by taking...

Endocannabinoid remodeling in murine cachexic muscle associates with catabolic and metabolic regulation
Biochim Biophys Acta Mol Basis Dis. 2024 Apr 21;1870(5):167179. doi: 10.1016/j.bbadis.2024.167179. Online ahead of print.ABSTRACTMuscle degeneration is a common feature in cancer cachexia that cannot be reversed. Recent advances show that the endocannabinoid system, and more particularly cannabinoid receptor 1 (CB1), regulates muscle processes, including metabolism, anabolism and regenerative capacity. However, it is unclear whether muscle endocannabinoids, their receptors and enzymes are responsive to cachexia and exercise. Therefore, this study investigated whether cachexia and exercise affected muscle endocannabinoid si...

LAGE3 promotes angiogenesis on hepatocellular carcinoma by stabilizing VEGFA mRNA
Biochim Biophys Acta Mol Basis Dis. 2024 Apr 21;1870(5):167196. doi: 10.1016/j.bbadis.2024.167196. Online ahead of print.ABSTRACTRNA modification plays important roles in various physiological and pathological process. LAGE3 is a component of EKC/KEOPS complex, which is probably involved in the formation of a threonylcarbamoyl group on adenosine at position 37 (t(6)A37) in tRNAs, but its exact role in HCC is less studied. Our study reveals that LAGE3 exhibits upregulated expression in HCC compared with normal hepatocellular tissue. High expression of LAGE3 promotes hepatocellular cell proliferation and migration. Further i...

Decorin suppresses stemness and migration potential of malignant peripheral nerve sheath tumor through inhibiting epidermal growth factor receptor signaling
Biochim Biophys Acta Mol Basis Dis. 2024 Apr 21:167181. doi: 10.1016/j.bbadis.2024.167181. Online ahead of print.ABSTRACTCancer stem cells (CSCs) play pivotal roles in the growth, invasion, metastasis, chemo-resistance in malignant peripheral nerve sheath tumor (MPNST). The current characterization of CSCs in MPNST is not complete. Decorin is a critical regulator of microenvironment, but its expression and function in CSCs of MPNST has not been studied. In the current study, Decorin levels and its relationship with lung and liver metastasis were determined in clinical specimens. Decorin expression in CD133-positive or CD44...

Effects of stand-alone polar residue on membrane protein stability and structure
Biochim Biophys Acta Biomembr. 2024 Apr 21:184325. doi: 10.1016/j.bbamem.2024.184325. Online ahead of print.ABSTRACTHelical membrane proteins generally have a hydrophobic nature, with apolar side chains comprising the majority of the transmembrane (TM) helices. However, whenever polar side chains are present in the TM domain, they often exert a crucial role in structural interactions with other polar residues, such as TM helix associations and oligomerization. Moreover, polar residues in the TM region also often participate in protein functions, such as the Schiff base bonding between Lys residues and retinal in rhodopsin-...
