Estrogen receptor alpha 36 (ERα36) is a variant of the canonical estrogen receptor alpha (ERα66), widely expressed in hormone sensitive cancer cells and whose high expression level correlates with a poor survival prognosis for breast cancer patients. While ERα36 activity have been related to breast cancer progression or acquired resistance to treatment, expression level and location of ERα36 are poorly documented in the normal mammary gland. Therefore, we explored the consequences of a ERα36 overexpression in vitro in MCF-10A normal mammary epithelial cells and in vivo in a unique model of MMTV-ERα36 transgenic mouse strain wherein ERα36 mRNA was specifically expressed in the mammary gland...

Capsular contracture or capsular fibrosis is the most common complication following breast augmentation with implants. Sonography is usually the initial imaging test performed to examine a suspicious implant. In contrast to the large number of patients developing capsular fibrosis there is only sparse literature reporting about sonographic findings. In this letter after a brief review of normal sonographic findings after breast augmentation, established ultrasound findings suggestive of capsular fibrosis (deformity, increased number of radial folds and thickening of the fibrous capsule) are discussed...

Eric Swanson
BACKGROUND: The safety of augmentation mastopexy has been questioned. Staging has been recommended for women deemed to be at higher risk, such as women with greater degrees of ptosis. Most existing studies evaluate women treated with multiple methods, including the traditional Wise pattern. This retrospective study specifically evaluates vertical augmentation mastopexy. A simple algorithm is introduced. METHODS: From 2002 to 2016, 252 women underwent consecutive vertical augmentation mastopexies performed by the author, with no staged surgery...

Autologous breast reconstruction using the deep inferior epigastric artery perforator (DIEP) flap has become increasingly popular because of its unique advantages. However, compared with some other forms of abdominal-based autologous reconstruction, DIEP flaps are associated with an increased risk of venous congestion. Many techniques-or lifeboats-have been introduced to diagnose and treat this potentially devastating complication. In this case report, we describe a novel strategy to augment venous drainage when venous congestion is encountered...

BACKGROUND: Breast augmentation is among the most frequently performed cosmetic plastic surgeries. Providing patients with "realistic" 3D simulations of breast augmentation outcomes is becoming increasingly common. Until recently, such programs were costly and required significant equipment, training, and office space. New simple user-friendly cloud-based programs have been developed, but to date there remains a paucity of objective evidence comparing these 3D simulations with the post-operative outcomes...

The augmented reality on smart glasses allows the surgeon to visualize three-dimensional virtual objects during surgery, superimposed in real time to the anatomy of the patient. This makes it possible to preserve the vision of the surgical field and to dispose of added computerized information without the need to use a physical surgical guide or a deported screen. TECHNIQUE: The three-dimensional objects that we used and visualized in augmented reality came from the reconstructions made from the CT-scans of the patients...

Breast cancer is reported as the most frequent tumor with limited treatments among the female worldwide. Galangin, a natural active compound 3, 5, 7-trihydroxyflavone, is a type of bioflavonoid isolated from the Alpinia galangal root and suggested to induce apoptosis in various cancers. Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is an effective anti-tumor agent for human breast cancer. Promoted expression of CHOP, a down-streaming transcription factor for endoplasmic reticulum stress (ER stress), enhanced death factor 4 (DR4) activity and accelerated reactive oxygen species (ROS) as well as cell death...

BACKGROUND: Human acellular dermal matrices (ADMs) have enabled successful breast reconstructions while decreasing muscle donor morbidity and pain for the patient. However, some literature reports indicate an increase in complications, especially infection. The decellularization and terminal sterilization properties of DermACELL (D-ADM), a human ADM, may reduce the rate of complications in augmented breast reconstruction while still maintaining successful outcomes. In the study presented here, we evaluate the quality and safety of outcomes with the use of D-ADM during tissue expander breast reconstruction...

BACKGROUND: Breast augmentations are commonly performed aesthetic surgical procedures. As the breast is a changeable structure, the ideal location of an implant would be a plane that can adjust to the dynamic changes of the breast. We present a modified dual-plane technique for breast augmentation using the fascia for thin patients. METHODS: Between June 2014 and June 2015, 27 patients with small breasts underwent breast augmentation using the modified dual-plane technique...

Tyrosine kinase signalling within cancer cells is central to the establishment of an immunosuppressive microenvironment. Although tyrosine kinase inhibitors act, in part, to augment adaptive immunity, the increased heterogeneity and functional redundancy of the tyrosine kinome is a hurdle to achieving durable responses to immunotherapies. We previously identified the Shc1 (ShcA) scaffold, a central regulator of tyrosine kinase signalling, as essential for promoting breast cancer immune suppression. Herein we show that the ShcA pathway simultaneously activates STAT3 immunosuppressive signals and impairs STAT1-driven immune surveillance in breast cancer cells...

3D visualization of breast tumors are shown to be effective by previous studies. In this paper, we introduce a new augmented reality application that can help doctors and surgeons to have a more accurate visualization of breast tumors; this system uses a marker-based image-processing technique to render a 3D model of the tumors on the body. The model can be created using a combination of breast 3D mammography by experts. We have tested the system using an Android smartphone and a head-mounted device. This proof of concept can be useful for oncologists to have a more effective screening, and surgeons to plan the surgery...

Tumor cells capture the signaling pathways used by normal tissue to promote their own survival and dissemination and among them, the NF-κB and MAPK pathways (ERK, JNK and p38). MAPK activation has ambiguous effects on tumor cell fate depending on cell type, cancer stage and the engaged MAPK isoforms. A synthetic peptide named LyeTx II, derived from the venom of the Brazilian spider Lycosa erythrognatha, was capable of increasing MDA-MB-231 aggressive breast cancer cell proliferation as indicated by MTT and BrdU (5-bromo-2'-deoxyuridine) incorporation assay and cell migration...

Myeloperoxidase (MPO) and eosinophil peroxidase (EPO) are heme-containing enzymes, well known for their antimicrobial activity, are released in high quantities by infiltrating immune cells in breast cancer. However, the functional importance of their presence within the tumour microenvironment is unclear. We have recently described a new role for peroxidases as key regulators of fibroblast and endothelial cell functionality. In the present study, we investigate for the first time, the ability of peroxidases to promote breast cancer development and progression...

Fatty acid synthase (FASN), the key enzyme for endogenous synthesis of fatty acids, is overexpressed and hyperactivated in a biologically aggressive subset of sex steroid-related tumors, including breast carcinomas. Using pharmacological and genetic approaches, we assessed the molecular relationship between FASN signaling and estrogen receptor alpha (ERα) signaling in breast cancer. The small compound C75, a synthetic slow-binding inhibitor of FASN activity, induced a dramatic augmentation of estradiol (E2)-stimulated, ERα-driven transcription...

REVIEW
Jin Tae Hong, Dong Ju Son, Chong Kil Lee, Do-Young Yoon, Dong Hun Lee, Mi Hee Park
Interleukin-32 (IL-32) is a novel cytokine involved in inflammation and cancer development. IL-32 gene consists of eight small exons, and IL-32 mRNA has nine alternative spliced isoforms, and was thought to be secreted because it contains an internal signal sequence and lacks a transmembrane region. IL-32 is initially expressed selectively in activated T cells by mitogen and activated NK cells and their expression is strongly augmented by microbes, mitogens, and other cytokines. The IL-32 is induced mainly by pathogens and pro-inflammatory cytokines, but IL-32 is more prominent in immune cells than in non-immune tissues...
