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...

Breast cancer in young women is uncommon, but the second most frequent cause of death in this age group. Young women with breast cancer have a worse prognosis than middle-aged women, with a higher risk of local recurrence, distant disease and breast cancer death. This can partly be explained by diagnosis at a later stage, and a higher proportion of tumors with unfavourable characteristics. However, in women with tumors of the luminal B subtype, low age remained an independent prognostic factor of DDFS and LRFS after correction for stage, tumor characteristics and treatment...

BACKGROUND: African American (AA) women are more likely to be given a diagnosis of breast cancer at an early age, experience morbidity after treatment, and exhibit disparities in survivorship. Although psychosocial well-being is largely studied among breast cancer survivors, data are sparse regarding young AA survivors. OBJECTIVE: This integrative review examined psychosocial concerns in survivorship among young AA survivors using a quality-of-life framework. METHODS: PubMed, CINHAL, EMBASE, PsychINFO, and Scopus were searched for articles exploring psychosocial well-being in young AA survivors...

A breast cholesterol granuloma is a rare benign condition that can be a pitfall in diagnosing breast cancer. We describe a cholesterol granuloma in the breast mimicking breast cancer on sonography. The mass was confirmed to be a cholesterol granuloma through a core needle biopsy, but an excisional biopsy was eventually performed due to suspicious sonographic appearance and histopathological examination of the specimen confirmed the diagnosis. © 2017 Wiley Periodicals, Inc.

Protein tyrosine kinase 6 (PTK6; also known as Brk) is closely related to the Src family kinases, but lacks a membrane-targeting myristoylation signal. Sublocalization of PTK6 at the plasma membrane enhances its oncogenic potential. To understand the mechanism(s) underlying the oncogenic property of plasma-membrane-associated PTK6, proteins phosphorylated by membrane-targeted myristoylated PTK6 (Myr-PTK6) were enriched and analyzed using a proteomics approach. Eps8 which was identified by this method is phosphorylated by Myr-PTK6 in HEK293 cells...

The chemokine CXCL10 and its receptor CXCR3 play a role in breast cancer metastasis to bone and osteoclast activation. However, the mechanism of CXCL10/CXCR3-induced intracellular signaling has not been fully investigated. To evaluate CXCL10-induced cellular events in the mouse breast cancer cell line 4T1, we developed a new synthetic CXCR3 antagonist JN-2. In this study, we observed that secretion of CXCL10 in the supernatant of 4T1 cells was gradually increased during cell growth. JN-2 inhibited basal and CXCL10-induced CXCL10 expression and cell motility in 4T1 cells...

Paclitaxel (PTX) is a effectively chemotherapeutic agent which is extensively able to treat the non-small cell lung, pancreatic, breast and other cancers. But it is a practically insoluble drug with water solubility less than 1 µg/mL, which restricts its therapeutic application. To overcome the problem, hyaluronic acid-complexed paclitaxel nanoemulsions (HPNs) were prepared by ionic complexation of paclitaxel (PTX) nanoemulsions and hyaluronic acid (HA) to specifically target non-small cell lung cancer. HPNs were composed of DL-α-tocopheryl acetate, soybean oil, polysorbate 80, ferric chloride, and HA and fabricated by high-pressure homogenization...

To investigate the recurrence pattern and subsequent survival outcomes in young breast cancer population, 483 young patients (≤ 35) and 739 elderly patients (≥ 65), who received mastectomy or breast-conserving surgery from 2008 to 2012, were included in this study. The young population presented with a higher rate of pathologic tumor stage (P < 0.001), positive pathologic lymph node (P < 0.001), grade III tumors (P < 0.001), and lymphovascular invasion (P < 0.001). With a median follow-up of 56...

Women with breast cancer frequently report distressing symptoms during and after treatment that can significantly erode quality of life (QOL). Symptom burden among women with breast cancer is of complex etiology and is likely influenced by disease, treatment, and environmental factors as well as individual genetic differences. The purpose of the present study was to examine the relationships between genetic polymorphisms within Neurotrophic tyrosine kinase receptor 1 (NTRK1), Neurotrophic tyrosine kinase receptor 2 (NTRK2), and catechol-O-methyltransferase ( COMT) and patient symptom burden of QOL, pain, fatigue, anxiety, depression, and sleep disturbance before, during, and after treatment for breast cancer in a subset of participants ( N = 51) in a randomized clinical trial of a novel symptom-management modality for women with breast cancer undergoing chemotherapy...

Tumor cell metabolism is a promising target for various cancer treatments. Apart from aerobic glycolysis, cancer cell growth is dependent on glutamine (Gln) supply, leading to their survival and differentiation. Therefore, we examined whether treatment with TNF-related apoptosis-inducing ligand (TRAIL) sensitizes MDA-MB-231 cells to apoptosis under Gln deprivation condition (TRAIL/Gln deprivation). Gln deprivation decreased cell proliferation as expected, but did not induce remarkable cell death. TRAIL/Gln deprivation, however, significantly increased growth inhibition and morphological shrinkage of MDA-MB-231 cells compared to those induced by treatment with either Gln deprivation or TRAIL alone...

BACKGROUND: Tumor hypoxia induces the expression of several genes via the hypoxia-inducible transcription factor-1 alpha (HIF-1a). It is associated with the prognosis of several cancers. We studied the immunohistochemical expression of HIF-1a in patients with invasive ductal cancer (IDC) of the breast and the possible correlation with the maximum standardized uptake value of the primary tumor (pSUVmax) as well as other biological parameters. Prognostic significance of pSUVmax and expression of HIF-1a for the prediction of progression-free survival (PFS) was also assessed...

Snail1, a key transcription factor of epithelial-mesenchymal transition (EMT), is subjected to ubiquitination and degradation, but the mechanism by which Snail1 is stabilized in tumours remains unclear. We identify Dub3 as a bona fide Snail1 deubiquitinase, which interacts with and stabilizes Snail1. Dub3 is overexpressed in breast cancer; knockdown of Dub3 resulted in Snail1 destabilization, suppressed EMT and decreased tumour cell migration, invasion, and metastasis. These effects are rescued by ectopic Snail1 expression...

Axillary lymph node (ALN) status is an important prognostic factor for overall breast cancer survival. In current clinical practice, ALN status is evaluated before surgery via multimodal imaging and physical examination. Mammography is typically suboptimal for complete ALN evaluation. Currently, ultrasonography is widely used to evaluate ALN status; nonetheless, results may vary according to operator. Ultrasonography is the primary imaging modality for evaluating ALN status. Other imaging modalities including contrast-enhanced magnetic resonance imaging, computed tomography, and positron emission tomography/computed tomography can play additional roles in axillary nodal staging...

Breast cancers arising in young women are biologically more aggressive, and most of these patients are candidates to receive aggressive treatments that include the use of chemotherapy. As most of these tumors express the hormone receptors (i.e., luminal disease), these patients are also candidates to adjuvant endocrine therapy. Chemotherapy-induced amenorrhea showed to be prognostic in young patients with luminal breast cancer. However, the role of ovarian function suppression (OFS) in addition to standard adjuvant treatments has been largely debated over the past years...

Glutamine metabolism is emerging as one aspect of dysregulated metabolism of tumors. Triple-negative breast cancer (TNBC) cells are glutamine dependent, whereas luminal-type cells tend to be glutamine independent. Therefore, TNBC patients might benefit from therapies targeting glutamine metabolism. To investigate the clinical significance of glutamine metabolism, we examined expression and prognostic significance of glutaminase in tumor cells and tumor-infiltrating lymphocytes (TILs) in TNBC. We retrieved 658 surgically resected TNBCs and analyzed glutaminase expression in tumor cells and TILs by immunohistochemical staining...
