acne vulgaris/tyrosine

Increased fibroblast growth factor receptor-2 (FGFR2) signaling has been proposed to be involved in acne pathogenesis and explains acne lesions in Apert syndrome and unilateral acneiform nevus associated with gain-of-function point mutations of FGFR2. If, indeed, increased FGFR2 signaling plays a

OBJECTIVE Benzoxathiolone derivatives have shown anti-inflammatory and immunomodulatory potential in acne and psoriatic disorders. However, little is known about the molecular basis for these pharmacological effects. In this study, we decided to investigate the anti-inflammatory actions of a

BACKGROUND Tyrosine kinase inhibitors (TKIs) are a new group of drugs that show the activity against receptors of different growth factors leading to the inhibition of tumor cells growth and proliferation. To date, four different TKIs have been approved for RAI-refractory DTC or MTC: sorafenib,

Type A insulin resistance syndrome (TAIRS) is a rare subtype of congenital insulin resistance (IR), which is characterized by specific clinical manifestations without clear diagnostic criteria and is easily misdiagnosed or overlooked. Herein we present a case of TAIRS with acanthosis nigricans (AN),

In this paper, we characterize the novel human leucocyte antigen (HLA)-DPB1*2402 allele that we found in a patient suffering from acne vulgaris. In comparison to the closest related allele DPB1*0401, HLA-DPB1*2402 has a single nucleotide exchange at position 115 (202), T replaces G. In consequence,

Imatinib mesylate is a tyrosine kinase inhibitor used in the treatment of several malignancies. Its use, however, is associated with a number of toxic effects including adverse cutaneous reactions. Herein, we present a case of facial cystic acne in a patient receiving imatinib therapy for chronic

Tyrosine kinase inhibitors (TKIs) are targeted treatments for various cancers. Skin toxicities are one of the most common nonhematological side-effects of TKIs. We report an imatinib mesylate (IM) induced hyperpigmented acne rosacea (AR) and sunitinib-induced palmar hyperkeratosis in the case with

BACKGROUND "Gefitinib" is a first-generation epidermal growth factor receptor tyrosine-kinase inhibitor. More than half of patients receiving gefitinib develop acne-like eruption. Evozac(®) Calming Skin Spray (Evaux Laboratoires, Évaux-les-Bains, France) is made of Évaux thermal spring water and

OBJECTIVE The goal of this study was to assess the safety and tolerability of icotinib hydrochloride (BPI-2009H), a new selective epidermal growth factor receptor tyrosine kinase inhibitor (EGFR TKI), and to explore its pharmacokinetics (PK) and clinical activity in patients with advanced solid

BACKGROUND This phase I dose-escalating study investigated the tolerability and toxicity of the selective epidermal growth factor receptor tyrosine kinase inhibitor gefitinib ('Iressa', ZD1839) in Japanese patients with solid tumors. Thirty-one patients were included. METHODS Patients initially

The purpose of this study is to develop a new formulation of adapalene for the topical treatment of acne. We investigated applicability of polymeric nanocarriers based on tyrosine-derived nanospheres (TyroSpheres) for adapalene delivery. TyroSpheres effectively encapsulated adapalene and

The discovery that mutations in the EGFR gene are present in up to 50% of patients with lung adenocarcinoma, and the development of highly efficacious EGFR tyrosine kinase inhibitors (TKIs), has revolutionized the way this common malignancy is treated. Three generations of EGFR TKIs are now

OBJECTIVE To establish the safety and tolerability of ZD1839 (Iressa), a selective epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor, and to explore its pharmacokinetic and pharmacodynamic effects in patients with selected solid tumor types. METHODS This was a phase I dose-escalating

OBJECTIVE To investigate safety, tolerability, dose-related pharmacologic properties, and pharmacodynamics of ZD1839 (gefinitib, Iressa; AstraZeneca Pharmacueticals, Wilmington, DE), an epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor, in patients with solid tumor types known to

OBJECTIVE To investigate the tolerability, pharmacokinetics, and antitumor activity of the oral, selective epidermal growth factor receptor-tyrosine kinase inhibitor ZD1839 in patients with solid malignant tumors. METHODS This was an open, phase I, escalating multiple-dose tolerability and
