Abstract
In clinical trials, adenovirus vectors (AdVs) are commonly used platforms for human gene delivery therapy. High genome capacity and flexibility in gene organization make HAdVs suitable for cloning. Recent advancements in molecular techniques have influenced the development of genetically engineered adenovirus vectors showing therapeutic potential. Increased molecular understanding of the benefits and limitations of HAdVs in preclinical research and clinical studies is a crucial point in the engineering of refined oncolytic vectors. This review presents HAdV species (A-G) used in oncotherapy. We describe the adenovirus genome organizations and modifications, the possibilities oncolytic viruses offer, and their current limitations. Ongoing and ended clinical trials based on oncolytic adenoviruses are presented. This review provides a broad overview of the current knowledge of oncolytic therapy. HAdV-based strategies targeting tumors by employing variable immune modifiers or delivering immune stimulatory factors are of great promise in the field of immune oncologyy This approach can change the face of the fight against cancer, supplying the medical tools to defeat tumors more selectively and safely.

MYB interacts with androgen receptor, sustains its ligand-independent activation and promotes castration resistance in prostate cancer. Br J Cancer 2022; 126:1205-1214. [PMID: 34837075 PMCID: PMC9023474 DOI: 10.1038/s41416-021-01641-1] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2021] [Revised: 10/27/2021] [Accepted: 11/10/2021] [Indexed: 11/08/2022] Open
Abstract
BACKGROUND Aberrant activation of androgen receptor signalling following castration therapy is a common clinical observation in prostate cancer (PCa). Earlier, we demonstrated the role of MYB overexpression in androgen-depletion resistance and PCa aggressiveness. Here, we investigated MYB-androgen receptor (AR) crosstalk and its functional significance. METHODS Interaction and co-localization of MYB and AR were examined by co-immunoprecipitation and immunofluorescence analyses, respectively. Protein levels were measured by immunoblot analysis and enzyme-linked immunosorbent assay. The role of MYB in ligand-independent AR transcriptional activity and combinatorial gene regulation was studied by promoter-reporter and chromatin immunoprecipitation assays. The functional significance of MYB in castration resistance was determined using an orthotopic mouse model. RESULTS MYB and AR interact and co-localize in the PCa cells. MYB-overexpressing PCa cells retain AR in the nucleus even when cultured under androgen-deprived conditions. AR transcriptional activity is also sustained in MYB-overexpressing cells in the absence of androgens. MYB binds and promotes AR occupancy to the KLK3 promoter. MYB-overexpressing PCa cells exhibit greater tumorigenicity when implanted orthotopically and quickly regain growth following castration leading to shorter mice survival, compared to those carrying low-MYB-expressing prostate tumours. CONCLUSIONS Our findings reveal a novel MYB-AR crosstalk in PCa and establish its role in castration resistance.

Abstract
Although the incidence and mortality of prostate cancer have gradually begun to decline in the past few years, it is still one of the leading causes of death from malignant tumors in the world. The occurrence and development of prostate cancer are affected by race, family history, microenvironment, and other factors. In recent decades, more and more studies have confirmed that prostate microflora in the tumor microenvironment may play an important role in the occurrence, development, and prognosis of prostate cancer. Microorganisms or their metabolites may affect the occurrence and metastasis of cancer cells or regulate anti-cancer immune surveillance. In addition, the use of tumor microenvironment bacteria in interventional targeting therapy of tumors also shows a unique advantage. In this review, we introduce the pathway of microbiota into prostate cancer, focusing on the mechanism of microorganisms in tumorigenesis and development, as well as the prospect and significance of microorganisms as tumor biomarkers and tumor prevention and treatment.

[PMID: 34201346 PMCID: PMC8229436 DOI: 10.3390/cancers13122872] [Citation(s) in RCA: 45] [Impact Index Per Article: 15.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2021] [Revised: 05/29/2021] [Accepted: 05/31/2021] [Indexed: 01/10/2023] Open
Abstract
The CREB-binding protein (CBP) and p300 are two paralogous lysine acetyltransferases (KATs) that were discovered in the 1980s-1990s. Since their discovery, CBP/p300 have emerged as important regulatory proteins due to their ability to acetylate histone and non-histone proteins to modulate transcription. Work in the last 20 years has firmly established CBP/p300 as critical regulators for nuclear hormone signaling pathways, which drive tumor growth in several cancer types. Indeed, CBP/p300 are critical co-activators for the androgen receptor (AR) and estrogen receptor (ER) signaling in prostate and breast cancer, respectively. The AR and ER are stimulated by sex hormones and function as transcription factors to regulate genes involved in cell cycle progression, metabolism, and other cellular functions that contribute to oncogenesis. Recent structural studies of the AR/p300 and ER/p300 complexes have provided critical insights into the mechanism by which p300 interacts with and activates AR- and ER-mediated transcription. Breast and prostate cancer rank the first and forth respectively in cancer diagnoses worldwide and effective treatments are urgently needed. Recent efforts have identified specific and potent CBP/p300 inhibitors that target the acetyltransferase activity and the acetytllysine-binding bromodomain (BD) of CBP/p300. These compounds inhibit AR signaling and tumor growth in prostate cancer. CBP/p300 inhibitors may also be applicable for treating breast and other hormone-dependent cancers. Here we provide an in-depth account of the critical roles of CBP/p300 in regulating the AR and ER signaling pathways and discuss the potential of CBP/p300 inhibitors for treating prostate and breast cancer.

Lu C, Brown LC, Antonarakis ES, Armstrong AJ, Luo J. Androgen receptor variant-driven prostate cancer II: advances in laboratory investigations. Prostate Cancer Prostatic Dis 2020; 23:381-397. [PMID: 32139878 PMCID: PMC7725416 DOI: 10.1038/s41391-020-0217-3] [Citation(s) in RCA: 28] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2019] [Revised: 02/17/2020] [Accepted: 02/19/2020] [Indexed: 02/07/2023]
Abstract
Background: The androgen receptor (AR) is a key prostate cancer drug target.
Suppression of AR signaling mediated by the full-length AR (AR-FL) is the
therapeutic goal of all existing AR-directed therapies. AR-targeting agents
impart therapeutic benefit, but lead to AR aberrations that underlie disease
progression and therapeutic resistance. Among the AR aberrations specific to
castration-resistant prostate cancer (CRPC), AR variants (AR-Vs) have
emerged as important indicators of disease progression and therapeutic
resistance. Methods: We conducted a systemic review of the literature focusing on recent
laboratory studies on AR-Vs following our last review article published in
2016. Topics ranged from measurement and detection, molecular origin,
regulation, genomic function, and preclinical therapeutic targeting of
AR-Vs. We provide expert opinions and perspectives on these topics. Results: Transcript sequences for 22 AR-Vs have been reported in the
literature. Different AR-Vs may arise through different mechanisms, and can
be regulated by splicing factors and dictated by genomic rearrangements, but
a low-androgen environment is a prerequisite for generation of AR-Vs. The
unique transcript structures allowed development of in-situ and in-solution
measurement and detection methods, including mRNA and protein detection, in
both tissue and blood specimens. AR variant-7 (AR-V7) remains the main
measurement target and the most extensively characterized AR-V. Although
AR-V7 co-exists with AR-FL, genomic functions mediated by AR-V7 do not
require the presence of AR-FL. The distinct cistromes and transcriptional
programs directed by AR-V7 and their co-regulators are consistent with
genomic features of progressive disease in a low-androgen environment.
Preclinical development of AR-V-directed agents currently focuses on
suppression of mRNA expression and protein degradation as well as targeting
of the amino-terminal domain. Conclusions: Current literature continues to support AR-Vs as biomarkers and
therapeutic targets in prostate cancer. Laboratory investigations reveal
both challenges and opportunities in targeting AR-Vs to overcome resistance
to current AR-directed therapies.
