Introducing Genes With Significant Role in Migraine: An Interactomic Approach
Introduction: Migraine is a severe kind of headache with the chance hereditary of 50%. Molecular studies can promote understanding of migraine pathophysiology. One of which is bioinformatics approach that could provide additional information related to the identified biomarkers.
Methods: In this research, migraine genes are studies in terms of interaction pattern to introduce important individuals. Through STRING database Plug-in in Cytoscape, candidate genes for migraine were retrieved and analyzed by related applications. Based on centrality and action types (expression, activation, and inhibition) genes were screened.
Results: Numbers of 33 central genes including seven hub-bottlenecks were identified which 70% of central genes were involved in expression action with each other. Activation was dominate action relative to inhibition between the central genes.
Conclusion: The finding indicates that insulin is the most important gene relative to migraine. It seems regulation of metabolism play critical role in control of migraine
AURICULAR ENLARGEMENT: AN ATYPICAL PRESENTATION OF OLD WORLD CUTANEOUS LEISHMANIASIS
The auricle is an extremely rare site for cutaneous leishmaniasis (CL) in Old World, which tends to be a benign disease with self-healing small nodules such as the “oriental sore”. However, in the New World, there is a type of CL of the ear, named as “chiclero's ulcer” which is caused by Leishmania mexicana. Herein, we describe a case of massive auricular enlargement due to Old World CL

CD44-specific short peptide A6 boosts cellular uptake and anticancer efficacy of PEGylated liposomal doxorubicin in vitro and in vivo
Abstract Although liposomes have improved patient safety and the pharmacokinetic profile of free drugs, their therapeutic efficacy has only shown marginal improvement. The incorporation of active-targeted ligands to enhance cellular uptake has shown promise in preclinical studies. However, no active-targeted liposomes have successfully translated into clinical use thus far. This study aimed to evaluate the targeting ability and antitumor efficiency of A6, a specific short peptide (KPSSPPEE) when incorporated into PEGylated liposomal doxorubicin (PLD). The results revealed significantly enhanced cellular uptake. The cytotoxicity of the formulations was determined by 3 h and 6 h incubation of formulations with cells, followed by 48 h incubation to evaluate the targeted ability of the formulations and the results indicated the higher cytotoxicity of A6-PLD (IC50 of 7.52 µg/mL after 6 h incubation) in the CD44 overexpressing C26 cell line compared to non-targeted PLD (IC50 of 15.02 µg/mL after 6 h incubation). However, CD44-negative NIH-3T3 cells exhibited similar uptake and in vitro cytotoxicity for both A6-PLD (IC50 of 38.05 µg/mL) and PLD (IC50 of 34.87 µg/mL). In animal studies, A6-PLD demonstrated significantly higher tumor localization of doxorubicin (Dox) (~ 8 and 15 µg Dox/g tumor for 24 and 48 after injection) compared to PLD (~ 6 and 8 µg Dox/g tumor for 24 and 48 after injection), resulting in effective inhibition of tumor growth. The median survival time (MST) for Dextrose 5% was 10, PLD was 14 and A6-PLD was 22 days. In conclusion, A6-PLD, a simple and effective targeted liposome formulation, exhibits high potential for clinical translation. Its improved targetability and antitumor efficacy make it a promising candidate for future clinical applications
