abstract breast cancer is a multifactorial disease. benign breast disease (bbd) is one of the most important risk factors for breast cancer. the etiology of bbd is unknown. it is divided into nonproliferative and proliferative diseases. the selection of studies will be based on titles, abstract screening, inclusion and exclusion criteria, and quality assessment. previous studies have shown that...

Apoptosis and proliferation are processes associated with the development and progression of breast cancer. The sensitivity of tumour cells to the induction of apoptosis depends on the balance between pro- and anti-apoptotic proteins. The expression of Bak and Bcl-2 was examined using an immunohistochemical method in 71 primary breast cancers. Furthermore, Bcl-2 and Bak were assessed in the nor...

Zatloukal J . , J . Lorenzová, F. Tich ̆, A. Neãas, H. Kecová, P. Kohout: Breed and Age as Risk Factors for Canine Mammary Tumours. Acta Vet. Brno 2005, 74: 103-109. Mammary tumours in 214 dogs were evaluated at the Department of Surgery and Orthopaedics, Veterinary and Pharmaceutical University Brno, between 1997 and 2001. Lesions of the mammary gland were classified as dysplasia/hyperplasia, b...

Mutations in the p63 gene have been identified in five types of syndromic ectodermal dysplasias (EDs) with overlapping phenotypes: Ectrodactyly-Ectodermal dysplasia-Clefting (EEC syndrome, MIM 604292), Ankyloblepharon-Ectodermal dysplasia-Clefting (AEC syndrome, MIM 106260) [3], Acro-Dermato-Ungueal-Lacrimal-Tooth (ADULT syndrome, MIM 103285), Rapp-Hodgkin (RHS syndrome, MIM 129400) and Limb-Ma...

Transformed nodule and ductal mammary cells were recovered by cell dissociation and transplantation of mammary cells from C57BL/Crgl mice treated with 7,12-dimethylbenz(a)anthracene. Four-week-old mice were divided into the following groups: Group A, not treated; Group B, 2 pituitary isografts under the kidney capsule; Group C, 1.0 mg 7,12-dimethylbenz(a)anthracene intragastrically at 5 and 6 w...

Background. Female patients presenting amastia associated with ectodermal dysplasia are not frequently encountered, but they are of great clinical interest and surgically demanding. Traditionally, skin alterations related to Ectodermal Dysplasia have addressed plastic surgeons to perform a two-stage approach in amastia associated with this congenital pathologic condition. This article describes...

Background X-linked hypohidrotic ectodermal dysplasia (XLHED), the most common form of ectodermal dysplasia, is caused by mutations in the gene EDA. While only affected men develop the full-blown clinical picture, females who are heterozygous for an EDA mutation often also show symptoms such as hypodontia, hypotrichosis and hypohidrosis. These women may also suffer from malformations of the mam...

Spontaneous mammary tumors were seen in seven of the 12 breeding female rats aged 2 years. All mammary tumors were diagnosed as mammary dysplasia (MD). Bone mineral contents (BMC) and bone mineral density (BMD) of their lumbar vertebrae and femur were determined using dual energy X-ray absorptiometry (DXA). In rats with MD, body weight (BW), BMD of the lumbar vertebrae and BMC of the femur were...

History: Colleen, a 34 year old white female, presented for treatment of severe breast pain, known as mastalgia, of five years duration. The pain was cyclical (menstrually related), however, she had some tenderness throughout the entire month. Colleen described multiple lumps in each breast, and about two years prior had a large lump drained. It was at that time that her gynecologist termed her...

To investigate the role of membrane-type matrix metalloproteinase-1 (MT1-MMP) in mammary gland development and tumorigenesis, transgenic mice overexpressing MT1-MMP in mammary gland under the control of the mouse mammary tumor virus long terminal repeat-promoter were generated. The mouse mammary tumor virus/MT1-MMP transgenic mice displayed abnormalities in 82% of female mammary glands. The abn...
