James M Angelastro
The expression of activating transcription factor 5 (ATF5) correlates negatively with patient survival in different types of cancer. ATF5 is important for the survival and proliferation of cancer cells, and can be targeted to selectively trigger cancer cell apoptosis while sparing normal cells. Cell-penetrating peptides combined with a dominant negative ATF5 cargo have recently shown efficacy against brain, breast, melanoma, and prostate cancers.

The objective of this study was to retrospectively analyze the oncological outcomes of Japanese patients with metastatic castration-resistant prostate cancer (mCRPC) who received cabazitaxel. This study included a total of 63 consecutive Japanese mCRPC patients treated with cabazitaxel following the failure of docetaxel, and assessed the prognostic significance of cabazitaxel therapy in these patients focusing on the association of efficacies between two taxane agents. After treatment with cabazitaxel (median 5 cycles), prostate-specific antigen (PSA) decline was observed in 39 patients (61...

PURPOSE: Recently neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) have been reported to be inflammatory parameters that confer poorer outcome in metastatic castration-resistant prostate cancer (mCPRPC). However, these ratios have not been analyzed in patients treated with abiraterone acetate. We explored the relationship between different values of PLR and NLR and survival in mCPRCP treated with abiraterone and their possible relation with a prostate specific antigen (PSA) response...

Nucleobindin 2 has been reported that its high expression is associated with poor outcome and promotes cell migration and lymph node metastasis in breast cancer, colon cancer, and prostate cancer. However, we aimed to investigate the nucleobindin 2 expression in gastric cancer tissues and adjacent non-tumor tissues and its potential relevance to clinicopathological factors and prognosis using immunohistochemical analysis. In our study, nucleobindin 2 level in gastric cancer tissues was higher than in non-tumor tissues...

Accumulating evidence indicates that Engrailed-2 (EN-2), which is a homeobox-containing transcription factor, act as a candidate oncogene in prostate cancer (PCa). Even though there are some treatments targeting EN-2, however, it is limited because the mechanism of EN-2 upregulation in PCa cells is still unknown. In this study, we investigate the role of miR‑212 on EN-2 expression and explored the mechanism of prostate cancer survival and metastasis. The relative expression levels of miR‑212 and EN-2 in PCa samples and adjacent normal tissues as well as in PCa cell lines were detected by using quantitative real-time PCR...

Recent insights into the genomic aberrations that underlie and drive prostate cancer have redoubled efforts to molecularly stratify treatments based on predictive markers. Approximately 23% of patients with metastatic castration-resistant prostate cancer exhibit somatic or germline aberrations in genes implicated in DNA repair, such as BRCA2, BRCA1, ATM, CHEK2, and PALB2, as well as mismatch repair genes. At least 10% of men with advanced disease have germline mutations in DNA-repair genes (DRG). The enrichment of DRG defects in metastatic disease compared with localized, primary tumors suggests a possible role in carcinogenesis, disease progression, and potentially accounts for a more aggressive phenotype...

BACKGROUND: It has been shown that neutrophil count or an elevated neutrophil-to-lymphocyte ratio (NLR) as well as testosterone levels are separately associated with increased mortality in patients with localized prostate cancer. OBJECTIVE: We tested a combination of testosterone levels and white blood cell (WBC) counts to predict overall survival (OS) in a prospective cohort of patients treated with radiotherapy for localized prostate cancer. PATIENTS AND METHODS: The 381 patients included in this study were prospectively enrolled in phase 2 or 3 studies...

According to the CDC prostate cancer (CaP) has the highest incidence and second highest mortality rate amongst cancers in American men. Constitutive NF-κB activation is a hallmark of CaP and this pathway drives many pro-tumorigenic characteristics of CaP cells, including cell proliferation and survival. An activated NF-κB gene signature is predictive of CaP progression and biochemical recurrence following therapeutic intervention. However, the mechanisms that perpetuate NF-κB activation are incompletely understood...

CONTEXT: Radium-223 is an □ -particle transmitter with specific action on bone metastases. The Alpharadin in Symptomatic Prostate Cancer Patients (ALSYMPCA) study showed that radium-223 extended overall survival and delayed the onset of bone events in patients with symptomatic castration-resistant prostate cancer with bone metastases (mCRPC) and without visceral metastases, with a good safety profile. OBJECTIVE: To review the new scientific evidence on radium-223 based on prespecified and post-hoc analyses of the ALSYMPCA study and on early-access programs after the publication of the ALSYMPCA study, thereby providing new data on the management of patients with mCRPC...

In prostate cancer, oxidative stress and the subsequent Nrf2 activation promote the survival of cancer cells and acquired chemoresistance. Nrf2 links prostate cancer to endoplasmic reticulum stress, an event that triggers the unfolded protein response, aiming to restore cellular homeostasis as well as an adaptive survival mechanism. Glucose-regulated protein of 78 kD /immunoglobulin heavy chain binding protein (GRP78/BiP) is a key molecular chaperone in the endoplasmic reticulum that, when expressed at the cell surface, acts as a receptor for several signaling pathways enhancing antiapoptotic and proliferative signals...

Cell migration drives cell invasion and metastatic progression in prostate cancer and is a major cause of mortality and morbidity. However the mechanisms driving cell migration in prostate cancer patients are not fully understood. We previously identified the cancer-associated cell migration protein Tetraspanin 1 (TSPAN1) as a clinically relevant androgen regulated target in prostate cancer. Here we find that TSPAN1 is acutely induced by androgens, and is significantly upregulated in prostate cancer relative to both normal prostate tissue and benign prostate hyperplasia (BPH)...

The digit ratio has been used as a retrospective noninvasive biomarker to investigate the putative effects of prenatal exposure to androgens. In recent years, many scholars have paid attention to the association between 2D:4D (the second and fourth digits) and prostatic cancer. This study explored the prognostic significance of digit ratio in prostate cancer patients. We reviewed the progressive status and survival of 382 prostate cancer patients who had received hormone therapy at our institutions. Survival of clinicopathological variables analyzed as categorical variables were determined by the log-rank test...

BACKGROUND: Limited data are available for the use of agents in metastatic castration-resistant prostate cancer (mCRPC) beyond the third-line. We provide data during treatment with cabazitaxel (CAB), helping to improve the informed-consent process. PATIENTS AND METHODS: We retrospectively reviewed patients treated with fourth-line or beyond CAB for mCRPC after failure of previous therapies with docetaxel, abiraterone acetate, enzalutamide and/or radium-223. The progression-free survival (PFS) and the overall survival (OS) were estimated using the Kaplan-Meier method and compared to published data based on a structured literature review...

The 67 kDa high affinity laminin receptor (67LR) is a non integrin cell surface receptor for laminin, the major component of basement membranes. Interactions between 67LR and laminin play a major role in mediating cell adhesion, migration, proliferation and survival. 67LR derives from homo- or hetero-dimerization of a 37 kDa cytosolic precursor (37LRP), most probably by fatty acid acylation. Interestingly, 37LRP, also called p40 or OFA/iLR (oncofetal antigen/immature laminin receptor), is a multifunctional protein with a dual activity in the cytoplasm and in the nucleus...
