An integration of neuroimaging and serum proteomics analysis suggests immune and inflammation are associated with white matter microstructure changes in cerebral small vessel disease with depressive symptoms.

Introduction: Depressive symptoms are a common concomitant of cerebral small vessel disease (CSVD), of which pathogenesis requires more study. White matter microstructural abnormalities and proteomic alternation have been widely reported regarding depression in the elderly with CSVD. Exploring the relationship between cerebral white matter microstructural alterations and serum proteins may complete the explanation of molecular mechanisms for the findings from neuroimaging research of CSVD combined with depressive symptoms.

Serum proteomic biomarker investigation of vascular depression using data-independent acquisition: a pilot study.

Background: Vascular depression (VaD) is a depressive disorder closely associated with cerebrovascular disease and vascular risk factors. It remains underestimated owing to challenging diagnostics and limited information regarding the pathophysiological mechanisms of VaD. The purpose of this study was to analyze the proteomic signatures and identify the potential biomarkers with diagnostic significance in VaD.

Gene therapy: an emerging therapy for hair cells regeneration in the cochlea.

Sensorineural hearing loss is typically caused by damage to the cochlear hair cells (HCs) due to external stimuli or because of one's genetic factors and the inability to convert sound mechanical energy into nerve impulses. Adult mammalian cochlear HCs cannot regenerate spontaneously; therefore, this type of deafness is usually considered irreversible. Studies on the developmental mechanisms of HC differentiation have revealed that nonsensory cells in the cochlea acquire the ability to differentiate into HCs after the overexpression of specific genes, such as , which makes HC regeneration possible.

Sensitization of TRPV1 receptors by TNF-α orchestrates the development of vincristine-induced pain.

Vincristine is one of the most common anticancer drugs clinically employed in the treatment of various malignancies. A major side effect associated with vincristine is the development of neuropathic pain, which is not readily relieved by available analgesics. Although efforts have been made to identify the pathogenesis of vincristine-induced neuropathic pain, the mechanisms underlying its pathogenesis have not been fully elucidated.

Synthesis and biological evaluation of naphthalimide-polyamine conjugates modified by alkylation as anticancer agents through p53 pathway.

In this study, a series of novel naphthalimide-polyamine conjugates modified by alkylation at the terminal of the polyamine chain were synthesized. These novel conjugates were evaluated for their anti-cancer activities. The results revealed that the length of the polyamine chain and the terminal alkyl group had influences on anticancer activities.

Design, Synthesis and Evaluation of Naphthalimide Derivatives as Potential Anticancer Agents for Hepatocellular Carcinoma.

Two kinds of naphthalimide derivatives were synthesized and evaluated for in vitro their anti-hepatocellular carcinoma properties. Compound with a fused thiazole fragment to naphthalimide skeleton inhibited cell migration of SMMC-7721 and HepG2, and further in vivo trials with two animal models confirmed that compound moderately inhibited primary H22 tumor growth (52.6%) and potently interrupted lung metastasis (75.

Design, Synthesis, and Biological Evaluation of Mitochondria-Targeted Flavone-Naphthalimide-Polyamine Conjugates with Antimetastatic Activity.

Approximately 90% of cancer-associated deaths result from disseminated tumors, indicating the ineffectiveness of current therapies and the imperative need of antimetastatic drugs. A novel pharmacophore with flavonoid and naphthalimide moieties was constructed by using a fragment-based drug design and a series of eight flavone-naphthalimide-polyamine conjugates were synthesized. In vitro evaluation revealed that compound 6c with a homospermidine motif displayed better cell selectivity between cancerous and normal liver cells than amonafide did.
