Lung cancer is the most feared of all cancers because of its heterogeneity and resistance to available treatments. Cancer stem cells (CSCs) are the cell population responsible for lung cancer chemoresistance and are a very good model for testing new targeted therapies. Clomipramine is an FDA-approved antidepressant drug, able to inhibit in vitro the E3 ubiquitin ligase Itch and potentiate the p...

The Hippo tumor suppressor pathway, originally defined in fruit flies, regulates cellular proliferation and survival and exerts profound effects on normal mammalian cell fate and tumorigenesis. The present understanding of Hippo pathway components and mechanisms remains incomplete in cancer. WW domain-containing proteins regulate diverse biological processes through interaction with proline-tyr...

Itch is the most common dermatological symptom and worsens with stress. The general belief of a person in their own ability to cope in stressful situations, known as self-efficacy, is relevant in the management of chronic diseases other than skin diseases. The aim of this study was to explore the association between perceived self-efficacy, itch and stress among late-stage adolescents. The stud...

Pruritus is a frequently encountered symptom following burns. Higher intensity of itching has been associated with depth of the wounds and specific body locations but these differences are not well understood. Our aim was to investigate the intensity of post burn pruritus in grafted and non-grafted burns across anatomic areas and to report on itch-inducing factors and applied treatments. The st...

Circular RNAs with exonic sequences represent a special form of non-coding RNAs, discovered by analyzing a handful of transcribed genes. It has been observed that circular RNAs function as microRNA sponges. In the present study, we investigated whether the expression of circular RNAs is altered during the development of esophageal squamous cell carcinoma (ESCC). Using a TaqMan-based reverse tra...

Noncoding RNAs (ncRNAs) are the dominant product of eukaryotic transcription. These products range from short microRNAs (miRNAs) to long intergenic noncoding RNAs (lincRNAs). Circular RNAs composed of exonic sequences represent an understudied form of ncRNA that was discovered more than 20 years ago. Using a TaqMan-based reverse transcriptase polymerase chain reaction assay, we analyzed the rel...

Itch is a somatosensory percept that is triggered by irritants at the skin’s surface. However, the manner in which itch is coded in the nervous system remains almost completely unknown. Recent work has uncovered a key role of spinal interneurons in the modulation of itch. Here we discuss these recent discoveries in the context of our understanding of spinal microcircuitry, highlighting the poss...

Endothelin-1 (ET-1) has been implicated in nonhistaminergic itch. Here we used electrophysiological methods to investigate whether mouse superficial dorsal horn neurons respond to intradermal (id) injection of ET-1 and whether ET-1-sensitive neurons additionally respond to other pruritic and algesic stimuli or spinal superfusion of bombesin, a homolog of gastrin-releasing peptide (GRP) that exc...

Previous studies have revealed that TRPV1 and TRPA1 function downstream of many itch receptors, where they mediate inward current to trigger action potentials in primary afferents. Although other TRP channels, such as TRPV4, are expressed in primary afferents, whether or not they play an analogous role in itch was previously unknown. Now, Akiyama et al. provide evidence that TRPV4 is a key medi...
