This Breast Cancer Awareness Month, Diana Spencer takes a look at the current situation and the new therapies on the horizon. Breast cancer is the most common cancer globally, with around 2.3 million new cases every year, according to data from the World Health Organization (WHO). It represent...
Breast cancer is categorized into two main histological types, ductal and lobular, as well the far less common mucinous carcinoma, adenoid cystic carcinoma and mixed tumors (e.g. ductal plus lobular). Within the ductal category are inflammatory breast cancer (IBC), medullary carcinoma, tubular ...

Prevent disease.Once you know you carry a certain gene, you may be able to make lifestyle changes or get medical treatment so you don’t get sick. For example, women who carry the BRCA1 or BRCA2 gene mutation are at higher risk forbreast cancer. To lower their risk, they may choose ...
Gender:Breast cancer isthe most common cancerin women and occurs 100 times more commonly in women than in men. 性别:乳腺癌是女性最常见的癌症,女性的发病率是男性的100倍。 Family history:Family history is an important risk factor for breast cancer. For women with a BRCA1 or BRCA2 mutation, ...
(proteins). Breast cancer develops due to reasons, such as BRCA gene mutation and PIK3CA gene mutation etc. Ducts and lobules are the major components of a breast, and everything is held together by the connective tissue which surro...
In a population of individuals affected with a recessive genetic disorder, the occurrence is 1/50. Assuming Hardy- Weinberg Equilibrium, what is the best estimate of the frequency of the disease-causing allele in this population? Hemophilia, an X-linked recessive disorder, is common in Labrador ...
Asp-to-Asn substitution at the first position of the DxD TOPRIM motif of recombinant bacterial topoisomerase I is extremely lethal to E. coli. J. Mol. Biol. 385, 558–567 (2009). A paper reporting how a single active-site mutation turns a type IA topo into a highly lethal machine, ...
(a) What is a mutation? (b) What are the causes of mutation? How can mutations in the BRCA1 gene contribute to cancer? What is a point mutation and how does it occur? How do changes in DNA affect changes in adaptations? How common is a heritable genetic mutation that alters the numb...
cells must rely on other pathways to repair the accumulating double-strand breaks. In cells with a breast cancer gene (BRCA) mutation, homologous recombination – a main pathway for detecting and repairing double-stranded breaks – is not functional. The DNA cannot be fully repaired, and the ac...
