Induction of Specific MicroRNAs Inhibits Cutaneous Wound Healing

Induction of specific microRNAs inhibits cutaneous wound healing.

Chronic nonhealing wounds, such as venous ulcers (VUs), are a widespread and serious medical problem with high morbidity and mortality. The molecular pathology of VUs remains poorly understood, impeding the development of effective treatment strategies. Using mRNA expression profiling of VUs biopsies and computational analysis, we identified a candidate set of microRNAs with lowered target gene...

Cutaneous wound healing

Angiogenesis inhibitor TNP-470 inhibits murine cutaneous wound healing.

BACKGROUND TNP-470 (AGM-1470) is a potent inhibitor of angiogenesis with potential therapeutic applications in neoplastic and angio-proliferative diseases. This study evaluated its effect on cutaneous wound healing in a murine dorsal excisional wound model. MATERIALS AND METHODS Full-thickness wounds (1.60 cm2) were created on the dorsum of homozygous/hairless mice (7 to 9 weeks). Wound areas...

Chemokines in cutaneous wound healing.

Healing of wounds is one of the most complex biological events after birth as a result of the interplay of different tissue structures and a large number of resident and infiltrating cell types. The latter are mainly constituted by leukocyte subsets (neutrophils, macrophages, mast cells, and lymphocytes), which sequentially infiltrate the wound site and serve as immunological effector cells but...

Effects of Rat’s Licking Behavior on Cutaneous Wound Healing

Objective(s) Wound licking has been shown to advance wound healing among humans and many other animals. The present study evaluates the licking effects on healing of skin wound in rats. Materials and Methods Twenty four rats were assigned to 4 different groups randomly and two 3 cm longitudinal full thickness incisions were made on each dorsal and ventral side of rats. The ventral incisions ...
