Methylation status, mRNA and protein expression of the SMAD4 gene in patients with non-melanocytic skin cancers.

Background: SMAD4 is a potent tumor suppressor. SMAD4 loss increases genomic instability and plays a critical role in the DNA damage response that leads to skin cancer development. We aimed to investigate SMAD4 methylation effects on mRNA and protein expression of SMAD4 in cancer and healthy tissues from patients with basal cell carcinoma (BCC), cutaneous squamous cell carcinoma (cSCC), and basosquamous skin cancer (BSC).

Conservative Surgical Treatment of a Case of Placenta Accreta.

Placenta accreta syndromes are associated with increased maternal mortality and morbidity. Cesarean hysterectomy is usually performed in cases of placenta accreta syndrome. Fertility sparing methods can be applied.

Investigating KRAS/BRAF mutation in oropharyngeal squamous cell carcinomas: a preliminary study.

Objectives: This study aims to investigate the role of KRAS/BRAF gene mutation in the pathogenesis of oropharyngeal squamous cell carcinoma (OSCC).

Patients And Methods: A total of 26 OSCC patients (23 males, 3 females; mean age 60 years; range 41 to 77 years) diagnosed between January 2003 and November 2013 were included in the study. The methods used in our study were quantitative fluorescence polymerase chain reaction for KRAS/BRAF mutation analysis.

Determination of HER2 and p53 Mutations by Sequence Analysis Method and EGFR/Chromosome 7 Gene Status by Fluorescence in Situ Hybridization for the Predilection of Targeted Therapy Modalities in Immunohistochemically Triple Negative Breast Carcinomas in Turkish Population.

Triple negative breast cancer (TNBC), an agressive subtype accounts nearly 15 % of all breast carcinomas. Conventional chemotherapy is the only treatment modality thus new, effective targeted therapy methods have been investigated. Epidermal growth factor receptor (EGFR) inhibitors give hope according to the recent studies results.
