The glial cell line-derived neurotrophic factor (GDNF) family of ligands (GFLs) comprising of GDNF, neurturin, artemin, and persephin plays an important role in the development and maintenance of the central and peripheral nervous system, renal morphogenesis, and spermatogenesis. Here we review our current understanding of GFL biology, and supported by recent progress in the area, we examine their emerging role in endocrine-related and other non-hormone-dependent solid neoplasms. The ability of GFLs to elicit actions that resemble those perturbed in an oncogenic phenotype, alongside mounting evidence of GFL involvement in tumor progression, presents novel opportunities for therapeutic intervention...

The inhibitor of DNA binding and cell differentiation (Id) proteins are dominant negative regulators of the helix-loop-helix transcription factor family and play a key role during development as well as in vascular disorders and cancer. In fact, impairing the Id-protein activity in cancer cells reduces cell growth and even chemoresistance. Recently, we have shown that a synthetic Id-protein ligand (1Y) consisting of a cyclic nonapeptide can reduce the viability of the two breast cancer cell lines MCF-7 and T47D and of the bladder cancer cells T24 to about 50% at concentrations ≥100μM...

BACKGROUND: The Norwegian Breast Cancer Screening Program (NBCSP) was implemented across the country in 2005 and has been criticised for potential 'overdiagnosis', i.e. a breast cancer diagnosis that otherwise would not have been detected or treated in a woman's lifetime. We aimed to estimate overdiagnosis in the NBCSP based on the Norwegian Women and Cancer (NOWAC) study using both questionnaire information and record linkage information from NBCSP. METHOD: For 124,978 women aged 49-79 years from the NOWAC study, information on screened women could be cross-validated from the NBCSP database...

Purpose The use of traditional complementary/alternative medicine (TCAM) among children with cancer has been well documented. South America has a rich history of traditional healers and medicinal resources; however, little is known about the use of TCAM among children with cancer. We sought to investigate patterns, beliefs, and determinants of TCAM use among South American children with cancer. Methods A cross-sectional survey was administered to 199 children treated for cancer at institutions located in Buenos Aires, Argentina, and Montevideo, Uruguay...

PURPOSE: Alcohol consumption is an established and important risk factor for breast cancer incidence in the general population. However, the relationship between alcohol and mortality among women with breast cancer is less clear. This study examines the effect of alcohol consumption on mortality in women affected with breast cancer at baseline from a high-risk family breast and ovarian cancer registry. METHODS: We studied 1116 women affected with breast cancer at baseline from the Metropolitan New York Registry...

Helper Innate Lymphoid Cells (ILCs), the most recently identified population of the Innate Lymphoid Cell family, plays a fundamental role in the restoration of tissue integrity, in the protection against infiltrating pathogens as well as in tumor immune-surveillance. ILCs have been divided into three main subsets, ILC1, ILC2 and ILC3, that can be specifically activated by different signals coming either from pathogens or from other cell populations, including cancer cells. Following activation, ILCs are in turn able to promptly secrete a wide range of soluble mediators that modulate effector cell functions...

Learning of a serious illness is unique news. Nothing certain can be known about how it will affect the hearer's outlook on the future before a conception is established about the hearer's expectations and how he/she has understood the issue. For example, a person who has been expecting muscle tension to be an explanation for back pain but hearing that a cancer metastasis is the underlying cause, will inevitably be in shock. The healthcare system is not able to influence everything, but is usually given one possibility to make a good first impression when telling about a serious diagnosis...

Prior research demonstrates that family history influences breast cancer prevention decisions among healthy women at elevated risk of the disease. Drawing on in-depth interviews with 50 African American and White women, this study reveals an important psychological mechanism of this relationship: exposure to cancer among loved ones. Four distinct categories of cancer exposure (Abstract, Generalized, Practical, and Traumatic), distinguished by the characteristics of women's experiences with cancer among family members and close friends, are associated with differences in knowledge and decisions about breast cancer prevention options...

Inherited cardiomyopathies, including hypertrophic cardiomyopathy (HCM) and dilated cardiomyopathy (DCM), are the most common monogenic cause of cardiac disease and can rarely lead to sudden cardiac death (SCD). They are characterized by incomplete and age-dependent penetrance and are usually initially symptomatic in adulthood yet can present in childhood as well. Over 20 genes have been identified to cause HCM, and more than 40 genes are known to cause DCM. Genetic testing for these genes has been integrated into medical care; however, the psychological impact of genetic testing and the impact of the uncertainty that comes with receiving these results have not been well studied...

BACKGROUND: Prostate cancer (PC) is one of the known heritable cancers with individual variations attributed to genetic factors. BRCA1 and BRCA2 are tumour suppressor genes with crucial roles in repairing DNA and thereby maintaining genomic integrity. Germline BRCA mutations predispose to multiple familial tumour types including PC. METHODS: We performed a Pubmed database search along with review of reference lists from prominent articles to capture papers exploring the association between BRCA mtuations and prostate cancer risk and prognosis...

Acne vulgaris is an epidemic inflammatory disease of the human sebaceous follicle and represents the most common skin disease affecting about 85% of adolescents in Westernized populations. Acne vulgaris is primarily a disease of wealthy countries and exhibits higher prevalence rates in developed compared with developing countries. No acne has been found in non-Westernized populations still living under Paleolithic dietary conditions constraining hyperglycemic carbohydrates, milk, and dairy products. The high prevalence rates of adolescent acne cannot be explained by the predominance of genetic factors but by the influence of a Western diet that overstimulates the key conductor of metabolism, the nutrient- and growth factor-sensitive kinase mTORC1...

INTRODUCTION: The U.S. Preventive Services Task Force recommends that primary care providers screen unaffected women with a family history of BRCA mutation-associated cancers, but without a personal history of BRCA-related cancer, for referral to genetic counseling and potential genetic testing. METHODS: The 2015 National Health Interview Survey was analyzed in January 2017 to determine the rates at which unaffected adult women with a positive family history of BRCA-related cancers, assessed using the Family History Screen-7, reported discussing genetic testing with a provider, using genetic counseling services, and having genetic testing for increased cancer risk...

BACKGROUND: Clustering of patients with cutaneous T-cell lymphoma (CTCL) was reported in several jurisdictions around the world. This rare cancer is known to affect spouses and in some cases multiple members of the same family. These combined results suggest the existence of external disease triggers/promoters. We recently conducted the first comprehensive analysis of CTCL incidence and mortality in Canada, which revealed case clustering in several regions. OBJECTIVES: To extend our previous analysis on CTCL incidence across Canada and to provide all the collected data on CTCL patient incidence in Canada during the period of 1992 to 2010...

Telomere dysfunction resulting from telomere shortening and deregulation of shelterin components has been linked to the pathogenesis of age-related disorders, including cancer. Recent evidence suggests that BRCA1/2 (BRCA1 and BRCA2) tumor suppressor gene products play an important role in telomere maintenance. Although telomere shortening has been reported in BRCA1/2 carriers, the direct effects of BRCA1/2 haploinsufficiency on telomere maintenance and predisposition to cancer development are not completely understood...

OBJECTIVE: Sub-optimal colorectal cancer (CRC) evaluations have been attributed to both physician and patient factors. The primary objective of this study was to evaluate physician practice variation in patients with a higher risk of CRC. We wanted to identify the physician characteristics and the types of patient that were associated with missed screening opportunities; we also explored whether screening for CRC served as a proxy for better preventive care practices. METHODS: 213 board-certified family and internal medicine physicians participated in the study, conducted between September and December 2016...
