PYK2 promotes HER2-positive breast cancer invasion

Metformin, a biguanide, is one of the most commonly prescribed treatments for type 2 diabetes and has recently been recommended as a potential drug candidate for advanced cancer therapy. Although Metformin has...

In this study, microarray analysis was used for gene expression profiling in rat prostate tissue after exposure to EDCs and sex hormones over multiple time points (prepubertal through adulthood). We used dorsolateral prostate tissues from Sprague-Dawley rats (male offspring) and postnatally administered estradiol benzoate (EB) on postnatal days (PNDs) 1, 3, and 5, followed by treatment with additional hormones [estradiol (E) and testosterone (T)] on PNDs 90-200, as described by Ho et al. Microarray analysis was performed for gene expression profiling in the dorsolateral prostate, and the results were validated via qRT-PCR....

CONCLUSIONS: Type 1 diabetes in both genders and all ages was associated with significantly elevated SMRs for all-cause and mostly for diabetes per se and renal disease. PMID: 32741854 [PubMed - as supplied by publisher]

Do you guys think there is enough volume to support an outpatient interventional cancer pain &cancer rehab practice? I will be starting my PM&R residency training at one of the top programs in the country after this academic year (am an prelim medicine intern right now). And I ultimately want to help cancer survivors. I think with the continuing improvements with cancer treatments (most recently with immunotherapy), cancer will be/is a chronic disease with debilitating side effects that... cancer pain only practice

AbstractBackgroundApproximately 40% of pts with HR+, HER2 – ABC have mutations (mut) in PIK3CA, which encodes α-PI3K and leads to PI3K pathway hyperactivation and potentially ET resistance. ALP is a selective inhibitor of α-PI3K that, in combination with fulvestrant (FUL), significantly improved median progression-free survival (PFS) vs placebo + FUL i n pts with PIK3CA-mut, HR+ HER2– ABC in the phase 3 SOLAR-1 trial (11.0 vs 5.7 mo, respectively; HR 0.65; 95% CI, 0.50-0.85; P

Conclusion: In the present study, in addition to known breast cancer risk factors, BMI and type 2 diabetes mellitus had an independent impact on survival of the patients, highlighting the importance of health issues such as obesity and diabetes suboptimal performance in the treatment outcomes of early breast cancer patients in Iran.

The objective was to explore the potential of 131I‐trastuzumab for treatment of breast cancers. Radioiodination of trastuzumab was carried out by chloramine‐T method, purified by using PD‐10 column, and characterized by size exclusion high‐performance liquid chromatography on a gel column. In vitro studies were carried out in HER2+ cells to determine the specificity of the radioimmunoconjugate. Uptake and retention of 131I‐trastuzumab were determined by biodistribution studies in tumor‐bearing non‐obese diabetic/severe combined immunodeficiency and normal severe combined immunodeficiency mice. The radiochemic...

Abstract Breast cancer (BC) prognosis and risk were associated to obesity, metabolic syndrome and type 2 diabetes mellitus. Two Single Nucleotide Polymorphisms (SNPs) of the adrenergic receptor-2a gene (ADRA2A): rs1800544 and rs553668, have been associated to these metabolic disorders. We investigated these SNPs in BC risk and prognosis. A total of 102 BC patients and 102 healthy controls were included. The rs1800544 and rs553668 were determined by real-time PCR. Genotypes and haplotypes frequencies between patients and controls, and for different clinico-pathologic parameters were compared. We found a significant...

We have recently described that the human white adipose tissue (WAT) contains progenitors with cooperative roles in breast cancer (BC) angiogenesis, local and metastatic progression (Martin-Padura et al, 2012; Orecchioni et al, 2013). The biguanide metformin (met), commonly used for type 2 diabetes, might have activity against BC and we found it able to inhibit angiogenesis in vivo (Dallaglio et al, 2014; Orecchioni et al, 2014). We studied met and another biguanide, phenformin (phe), in vitro and in vivo in orthotopic NSG murine models of local and metastatic BC. As met is frequently administered with aspirin or atenolol ...

Conclusion: Our study found that breast cancer with T2DM had a higher expression of IGF1R, and the higher IGF1R was associated with negative Her2 expression.

Conclusions: The addition of M to AC in MBC patients receiving first line chemotherapy did not improve PFS compared with AC alone. M seems to have a protective effect on hematological toxicity. Final results including translational data will be available at SABCS 2014.
