Don ’ t Count on 23andMe to Detect Most Breast Cancer Risks, Study Warns

The DNA testing company, which has 10 million customers, misses nearly 90 percent of people with risky BRCA mutations. It says the criticism is overblown.

In this study, T cells deficient in TRAF6 display enhanced T cell activation, CD28-indpendent stimulation and resistance to Treg cell-mediated suppression (176). Although TLR signaling can promote T cell resistance to Treg cells, the precise molecular mechanism remains yet to be elucidated. It is worth noting that TLR stimulation of T cells increases cytokine production (173, 177), thus future studies should delineate the effect of TLR-MyD88 signaling vs. subsequently induced cytokines in generating resistance to Treg cells. Lastly, it is also crucial to evaluate the effect of TLR signaling on regulatory T cells which also...

This paper mainly aims to figure out the multiple ‐gene panel revealed mutational characteristics of breast cancer susceptibility genes in 481 Chinese women with familial breast cancer history.  AbstractGenetic testing for germline mutations inBRCA1/2 of patients with breast cancer (BC) is part of routine patient care. However,BRCA1/2 mutations account only for a fraction of familial BC. A custom panel of 22 gene sequencing was performed on each patient. Among the 481 female patients, 135 patients were detected to carry pathogenic (P)/likely pathogenic (LP) mutations (28.1%), which corresponded to 12 different can...

In conclusion, our results show that some challenges exist in the early detection of breast cancers in BRCA1 or BRCA2 mutation carriers. There are also some difficulties in approaching those individuals in Japanese society. PMID: 30980249 [PubMed - as supplied by publisher]

teiro Genetic testing allows for the identification of germline DNA variations, which are associated with a significant increase in the risk of developing breast cancer (BC) and ovarian cancer (OC). Detection of a BRCA1 or BRCA2 pathogenic variant triggers several clinical management actions, which may include increased surveillance and prophylactic surgery for healthy carriers or treatment with the PARP inhibitor therapy for carriers diagnosed with cancer. Thus, standardized validated criteria for the annotation of BRCA1 and BRCA2 variants according to their pathogenicity are necessary to support clinical decision-mak...

In this study, Lactobacillus plantarum (L. plantarum) KLDS1.0318 preserved in our laboratory was orally administered to CTX-treated mice to explore its potential effects to attenuate the toxic effects of CTX-induced by modulating intestinal immune response, promoting intestinal integrity and improving metabolic profile. BALB/c mice were randomly divided into six groups including normal control group (NC; non-CTX with sterile saline), model control group (MC; CTX-treated with sterile saline), CTX-treated with L. plantarum KLDS1.0318 (10 mL/kg) groups with three different doses (KLDS1.0318-L, 5 × 107 CFU/mL; KLDS1.0318...

Conclusion: The texture analysis for breast DCE-MRI proposed in this study demonstrated potential utility in HER2 2+ status discrimination. Background Human epidermal growth factor receptor 2 (HER2) is an orphan tyrosine kinase receptor. It is reported that HER2 is overexpressed in 15–20% of breast cancers. Overexpression of HER2 in breast cancer correlates with shortened disease-free survival. Compared with HER2-negative patients, patients with HER2-positive breast cancers have a poor prognosis, a high probability of lymph node metastasis and a high risk of recurrence (1–3). However, previous studies h...
