It is frequently linked with other disorders such as psychosis, cardiovascular disorders, diabetes, and depression, all of which may influence the disease's onset, trajectory, and treatment approaches. These comorbidities can affect the onset, progression, and management of AD. This review focuses to explore the interplay of AD and comorbidities, and to examine the interplay between multiple chronic conditions. The review found that AD and comorbidities have a complex and bidirectional relationship. Comorbidities can affect the onset, progression, and management of AD, and AD can also affect the management and outcomes of comorbidities. The review also found that comorbidities may have an impact on caregiver burden, healthcare utilization and mortality. The findings suggest that the management of AD should take into account the presence and management of comorbidities to improve the overall outcomes for patients with AD. The literature also suggests that the management of comorbidities should be integrated in the management of AD patients. Furthermore, the review highlights the critical role of timely detection and treatment of comorbidities in AD patients to delay onset and mitigate disease progression. Additionally, it is crucial to consider the influence of comorbidities when selecting treatment options and the management of side effects and adverse events in AD patients. The literature reviewed in this article suggests that a multidisciplinary approach is needed in managing AD patients with comorbidities, which includes regular screening, early detection, and management of comorbidities in addition to managing AD.</div></div>","PeriodicalId":8821,"journal":{"name":"Biochimica et biophysica acta.

Accumulating evidence indicates that fibroblast senescence plays a critical role in the impaired healing of diabetic wounds. Abnormal mitochondrial morphology has long been associated with cellular senescence and age-related pathologies, suggesting that mitochondrial dynamics are compromised during senescence. In this study, we explored the potential mechanisms through which adipose-derived mesenchymal stem cell-derived exosomes (ADSC-Exos) facilitate diabetic wound repair. We initially confirmed the presence of a substantial number of senescent fibroblasts in diabetic wound tissues. Subsequent investigations demonstrated that exosomes derived from adipose-derived stem cells can effectively alleviate fibroblast senescence. In-depth mechanistic analyses revealed that these exosomes suppress the expression of SMARCAL1, a chromatin remodeling protein, thereby enhancing the transcription of mitochondrial dynamin-related protein 1 (Drp1), and ultimately restoring mitochondrial dynamics and alleviating senescence in human dermal fibroblasts (HDFs). In vivo experiments further demonstrated that exosome administration significantly reduced HDFs senescence and accelerated wound healing in a diabetic mouse model. Collectively, our findings suggest that ADSC-Exos promote diabetic wound healing by mitigating HDFs senescence via the SMARCAL1-Drp1-mitochondrial dynamics pathway. This study elucidated the molecular mechanisms underlying exosome-mediated fibroblast senescence rescue and proposed a novel therapeutic strategy for diabetes-related wound management through targeted clearance of senescent cells.</div></div>","PeriodicalId":8821,"journal":{"name":"Biochimica et biophysica acta.

Here, we aimed to elucidate the functional role and underlying mechanisms of USP38 in obesity-induced VAs.Cardiac-specific Usp38 knockout (CKO) mice were commercially generated. Obesity was induced by feeding mice a high-fat diet (HFD), while control mice received a normal diet (ND). We found the USP38 expression was significantly elevated in cardiac tissues of obese mice. Cardiac-specific deletion of USP38 markedly improved metabolic profiles and attenuated pathological remodeling, evidenced by reduced fibrosis markers (α-SMA, collagen I, collagen III), hypertrophy markers (ANP, BNP, β-MHC), and aberrant ion channel expression (Cav1.2, Kv1.5, Kv2.1, Kv4.2, Kv4.3). Correspondingly, the incidence of inducible VAs was significantly reduced. Co-immunoprecipitation confirmed a direct interaction between USP38 and the Toll-like receptor-4 (TLR4) signaling pathway. Further analyses demonstrated that USP38 knockout effectively blunted TLR4-mediated CaMKII activation both in vivo and in vitro. Cardiac-specific USP38 knockout effectively mitigates obesity-induced cardiac hypertrophy, fibrosis, and electrical remodeling, significantly reducing susceptibility to ventricular arrhythmias via inhibition of the TLR4/CaMKII signaling pathway. Mechanically, USP38 interacts with TLR4 and prevents the proteasomal degradation of TLR4, stabilizing TLR4 and promoting the activation of its downstream mediators.

Malfunctions in primary cilia are associated with developmental disorders and various malignancies, including prostate cancer (PCa). Recent studies highlight the regulation of ciliogenesis, cilia length, and interaction among cilia-resident proteins, particularly within the ciliary hedgehog (Hh) signaling axis in oncogenesis, thereby positioning primary cilia as potential therapeutic targets. Nevertheless, the precise contribution of ciliary components to Hh pathway modulation in PCa remains poorly defined. This review integrates emerging evidence to elucidate the current state of knowledge on the structural and functional attributes of primary cilia, cilia-mediated molecular dynamics with Hh signaling, and their intersection in the context of PCa progression, including prostate development, carcinogenesis, and tumor microenvironment dynamics. Particular emphasis is placed on cilia-associated proteins, such as SCL/TAL1 interrupting locus (STIL), intraflagellar transport (IFT) family proteins, ADP-ribosylation factor (Arf) family proteins, transforming acidic coiled-coil protein-3 (TACC3), mitotic kinase Aurora A, and dual-specificity tyrosine-regulated kinase (DYRK), which have been mechanistically linked to PCa and modulate Hh signaling. However, their detailed contributions remain insufficiently characterized and warrant further investigation.
