High-risk HPV in penile carcinoma [53]. p16 protein expression was significantly higher

High-risk HPV in penile carcinoma [53]. p16 protein expression was significantly higher in penile carcinoma samples positive for high-risk HPVs independently of the subtype of penile squamous cell carcinoma compared to penile carcinoma HPV negative samples in our study. Some studies focused on p16 alterations in penile cancer, but with different emphases. One study found an overexpression of p16 in 29 of penile carcinomas, especially in connection with HPV infection [54]. Prowse et al. detected p16 overexpression in 46 of penile SCCs, which was significantly associated with HPVinfection [49]. However, Senba et al. described p16 overexpression in an equal amount of HPV-positive and HPV-negative penile carcinomas from Kenya [55]. Based in our data, we suggested the p16 could be a marker for penile carcinoma, confirming the diagnosis of malignant penile lesions with high-risk HPVs corroborating with previous studies with the same type of cancer [49,53,56]. This study identified two overexpressed genes, ANXA1 and p16, in penile squamous cell carcinoma positive for high-risk HPVs. To the best of our knowledge this report is the first to describe ANXA1 protein overexpression in penile carcinoma with high-risk HPV independently of the subtype. These genes are associated with various physiological processes including cellular differentiation, cell proliferation and signal transduction, suggesting that they have an important role in penile carcinogenesis. However, additional studies are required in order to elucidate their specific role in penile cancer with high-risk HPV.Author ContributionsConceived and designed the experiments: MFC LLV SMO PR.

Targets of neuronal innervations play a vital role in regulation of the survival and differentiation of innervating neurotrophin (NT)-responsive neurons [1]. The motor neurons and skeletal muscle (SKM) fibers innervations depend on each other strongly [2?]. Important communication between both tissues is mediated through the neuromuscular junction. Release and reception of various factors at other parts of both tissues must be considered as means of mutual influences [4]. Exchange of neurotrophins (NTs) and other molecules is likely to be an important source of nervemuscle communication. NTs potentiate presynaptic release of BI 78D3 neurotransmitter [5?] and are essential for motor neuron survival [7], as well as for the maintenance of postsynaptic characteristic develop and maturation of muscle. Synapse-forming axons have vital effect on cell-surface behavior at nerve-muscle contacts order AKT inhibitor 2 during synaptogenesis in co-cultures of rat ventral spinal cord neurons and myotubes [8]. Neuromuscular junction development has been identified with co-cultures of dissociated embryonic neurons and SKM cells [9]. Innervations induce formation of a mature SKM-like excitation-contraction coupling system in cultured human muscle cells [10]. Peripheral nerve recovery after crush injury was suppressed by chronic inflammation in peripheraltarget tissue [11]. Extracellular application of myosin II or skeletal muscle extract to neurons resulted in a robust increase in the number of axons initiated by each neuron or the number of survival neurons [12?3].
