BACKGROUND: Actinic keratosis (AK), a hyperkeratotic lesion induced by solar exposure, is the precancerous lesion that most frequently develops into squamous cell carcinoma. Cryotherapy, topical fluorouracil 5, topical diclofenac 3% gel and, more recently, ingenol mebutate are used in addition to surgery. However, these treatments have varying degrees of effectiveness and are not always tolerated due to side effects. In recent years, Photodynamic Therapy (PDT), has asserted itself as a new effective and safe method for the treatment of actinic keratoses with almost no side effects...

Actinic keratoses (AKs) are epidermal cutaneous neoplasia observed predominantly in middle-aged and older subjects with mainly photo type I and photo type II on sun-exposed surfaces as a result of DNA damage. AKs have historically been characterized as being "precancerous"; however, now it is considered by many authors a carcinoma in situ that can persist or progress to invasive squamous cell carcinoma (SCC) with metastatic potential. Despite the advances in the recognition of typical clinic, dermoscopic and histologic patterns, currently it is not yet possible to predict which AKs will progress to SCC...

BACKGROUND: Ingenol mebutat (IM)-gel is effective for the topical treatment of epithelial tumors, including actinic keratoses (AKs) or anogenital warts (AGW). AK patients treated with IM develop intensified inflammatory reactions on sights of prior clinical visible or palpable AKs as compared to the surrounding actinically damaged skin, suggesting the induction of a tumor cell-directed inflammation. AGW patients treated with IM develop even stronger inflammatory reactions with large erosions, suggesting a directed inflammatory response against HPV-infected keratinocytes...

Actinic keratosis (AK) is an in situ squamous cell carcinoma which is mostly found on sun-damaged skin, and it is prevalent among Caucasians. However, there is a lack of research on evaluating the treatment efficacy of ingenol mebutate (IM) on AK in Asians. This study was intended to analyze the treatment outcomes of IM on AK in Korean patients with regards to clinical, dermoscopic and histopathological aspects. A prospective study on 46 Korean patients who were diagnosed with AK and treated with IM was conducted...

Ion channels are important therapeutic targets, but the discovery of ion channel drugs remains challenging due to a lack of assays that allow high-throughput screening in the physiological context. Here we report C. elegans phenotype-based methods for screening ion channel drugs. Expression of modified human ether-a-go-go-related gene (hERG) potassium channels in C. elegans results in egg-laying and locomotive defects, which offer indicators for screening small-molecule channel modulators. Screening in worms expressing hERGA561V , which carries a trafficking-defective mutation A561V known to associate with long-QT syndrome, identifies two functional correctors Prostratin and ingenol-3,20-dibenzoate...

Actinic keratosis (AK) is a common skin lesion in adults which usually occurs on chronically photoexposed areas and considered as a precancerous lesion or a superficial squamous-cell carcinoma. Many classifications have been proposed and its diagnosis is generally clinical but, sometimes, its wide variety of presentations can make diagnosis difficult, even among expert observers. The malignant potential of AKs imposes an early diagnosis and treatment in order to reduce morbidity and mortality, and, for the characterization of photodamaged skin, noninvasive diagnostic techniques, such as dermoscopy, have proved to be useful, while multiple therapeutic strategies, lesion-directed versus field-directed therapies, are available for the treatment of AKs...

Antiretroviral therapy (ART) does not cure HIV-1 infection due to the persistence of proviruses in long-lived resting T cells. Strategies targeting these latently infected cells will be necessary to eradicate HIV-1 in infected individuals. Protein kinase C (PKC) activation is an effective mechanism to reactivate latent proviruses and allows for recognition and clearance of infected cells by the immune system. Several ingenol compounds, naturally occurring PKC agonists, have been described to have potent latency reversal activity...

Actinic keratosis (AK) is a common skin condition that results from exposure to chronic ultraviolet (UV) radiation. AK is characterized by visible, scaly lesions; sub-clinical lesions may also be present within a field of UV-exposed skin. These lesions exist on a disease continuum with squamous cell carcinoma. Field therapies, such as ingenol mebutate, aim to treat the visible and sub-clinical lesions within an area of sun-damaged skin. Areas covered: According to the SmPC, ingenol mebutate has a proposed dual mechanism of action that induces cell death necrosis with the production of a local pro-inflammatory response and stimulation of apoptosis...

BACKGROUND: Actinic keratoses are benign intraepithelial skin neoplasms that develop in photoexposed areas and can progress to invasive carcinoma. They are seen frequently in dermatological practice, occurring in 5.1% of consultations. Ingenol mebutate (IM) was recently approved in Brazil as a topical therapy for field cancerization in actinic keratosis. OBJECTIVE: To evaluate the clearance rate and adverse events in the treatment of actinic keratoses with ingenol mebutate...

Euphorbia kansui showed potent anti-HIV-1 activity during screening of a library composed of plant extracts from Euphorbiaceae and Thymelaeaceae families. Bioassay-guided isolation led to identification of ingenane esters as the active compounds. Further chemical modification resulted in 3-(2-naphthoyl)ingenol (23), which exhibited the most potent anti-HIV-1 activity. Compound 23 also acted as an HIV-1-latency-reversing agent on activation of HIV-1 replication in a latently infected U1 cell model and a T cell latent HIV-1 model JLat-A2...

BACKGROUND: Patients with multiple actinic keratoses (AKs) should be treated with field-directed therapy. Such treatments challenge patients' adherence due to out-of-pocket costs, length of treatment and severity of local skin reactions (LSRs). Effective physician-patient communication (PPC) may buffer therapy-related distress, thus improving quality of life, treatment satisfaction and adherence. OBJECTIVES: We evaluated the interplay between PPC, LSR intensity (safety) and lesion clearance rates (effectiveness) on treatment satisfaction, quality of life and treatment adherence among patients with multiple AKs receiving topical field-directed therapies...

Cutaneous squamous cell carcinoma (SCC) is among the most common cancers in humans, and many patients with SCC will develop multiple tumors within their lifetime. The field cancerization concept, originally proposed over 60 years ago, hypothesized that multiple primary cancers may arise simultaneously and coexist with subclinical precursor lesions within a defined field. Genetic sequencing of SCC and precursor lesions has identified what may be the earliest clonal proliferations in SCC development and confirmed that field cancerization in the skin is mediated by ultraviolet radiation...

Cutaneous field cancerization arises due to UV-induced carcinogenesis of a "field" of subclinically transformed skin and actinic keratoses (AKs) with a tendency to progress and recur. Commonly used treatment methods for multiple AKs include imiquimod, fluorouracil, ingenol mebutate, and photodynamic therapy; however, new options in field-directed therapy with superior efficacy, cosmesis, and convenience may appeal to patients. Ablative and nonablative lasers may fulfill these advantages and have been investigated as monotherapies and combination therapies for field cancerization...

Surgical excision is the first-choice treatment for basal cell carcinoma (BCC). Other treatments with topical agents such as 5-fluorouracil or imiquimod have also been suggested for use in superficial BCC (sBCC). Ingenol mebutate (IM) is a novel agent employed in the treatment of superficial actinic keratoses. The drug has been also successfully used in the treatment of sBCC. A case of large nodular BCC (nBCC) of the face in a 100-year-old inoperable woman is described. IM 0.015% gel was applied once daily for three consecutive days...

Hydroxycarbamide (HC) is the first-line treatment for certain myeloproliferative neoplasms, such as polycythemia vera and essential thrombocytosis (ET). In a subset of these patients long-term treatment with HC can result in the development of confluent actinic keratoses (AK) followed by invasive keratinocytic carcinomas ("squamous dysplasia"), preferentially on sun-exposed skin. Discontinuation or dose reduction of HC may result in partial improvement. A 59-year-old farmer after 14 years on HC (2 gr/d) and acetylsalicylic acid (100 mg/d) for ET, was referred for numerous, hyperkeratotic AK on face, scalp, and hands that could not be controlled with repeated ( N = 15) cryosurgery sessions in the previous 3 years...

INTRODUCTION: Ingenol mebutate is an actinic keratosis treatment, which has a dual action mechanism. It allows a rapid cellular death and a severe inflammation. OBSERVATION: We report the case of a 75 years old patient with a rapidly growing tumor 5 weeks after application of ingenol mebutate on typical actinic keratosis. Histological analysis after surgical excision showed an invasive squamous cell carcinoma (SCC); with aggressiveness signs: perineural infiltration and vascular permeation...
