Furthermore, intraperitoneal injection of minocycline (40 mg/kg) with ACR reduced the levels of MDA, IL-1β, and caspase-3-cleaved proteins in the cerebral cortex. Administration of minocycline exhibits both prophylactic and therapeutic properties against ACR-induced neurotoxicity primarily through anti-oxidant, anti-apoptotic, and anti-inflammatory properties.
This study aimed to investigate the anticancer potential of three tetracycline analogues chemically modified tetracycline-3 (COL-3), doxycycline (DOX), and minocycline (MIN) in leukemia models, with a particular focus on their cytotoxic effects and modulation of the JAK2/STAT3 signaling pathway. Among them, COL-3 emerges as the most potent analogue and acts through both JAK/STAT-dependent and -independent mechanisms. This work supports further investigation of COL-3 as a candidate for drug repurposing strategies in hematological malignancies.
Furthermore, the anxiety-like behaviors in NSUN5-deficient mice were also relieved by rmFGF2 or minocycline treatments. Taken together, our study unveils a previously unknown effect of NSUN5 on anxiety disorders and a role of NSUN5 in regulating OPCs-microglia interaction and synaptic plasticity of BLA.

Here, we use photoactivatable multi-inhibitor liposomes (PMILs) as a clinically translatable strategy to immunomodulate and enhance PDAC treatment using FDA-approved agents: minocycline for tumor priming by downregulating Tdp1, benzoporphyrin derivative incorporated into the liposomal bilayer for photodynamic priming (PDP) of the microenvironment, and irinotecan (IRI) for cytotoxicity. This combination achieved sustained local tumor regression, abscopal effects in untreated distant tumors, and a significant improvement in long-term survival (63%). By integrating clinically approved agents with non-overlapping mechanisms within a light-activated delivery platform, this approach enhances IRI efficacy, reprograms the TME, and promotes antitumor immunity, offering a translatable strategy to sensitize PDAC to chemo- and immunotherapy.
