Special Issue Information

Dear Colleagues,

It is well-known that breast and prostate cancers are related to female and male hormones, respectively. Recently, it has been established that male steroid hormones, such as androgen, play an important role in female breast cancer progression. For approximately a dozen years, the possibility of anti-estrogen therapy for both female and male non-small lung carcinoma patients has been a significant area of research. In addition, the peptide hormones released by psychological stress directly stimulate growth signals in solid cancers, such as ovarian and endometrial cancers. Research into hormone-dependent cancers continues to progress at a rapid pace.
This Special Issue of the International Journal of Molecular Sciences entitled “Hormone-Dependent Cancers: New Aspects of Biochemistry and Molecular Pathology 3.0”, will focus on recent advances in hormone and cancer research, such as the molecular action of hormone receptors, biochemical analysis of steroid or peptide hormones, growth or invasive signals of hormone-related cancers, and mechanisms of resistance of endocrine therapy. Contributions on these or related topics are welcome, including original research and full- and mini-reviews. Postdocs, Ph.D. students, and young researchers are all very welcome to contribute.

Dr. Yasuhiro Miki
Guest Editor

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Vitamin D regulates estrogen synthesis among other mechanisms involved in breast cancer (BC) development; however, no evidence has been found regarding its relationship with DNA repair capacity (DRC). Therefore, the objective of this study was to elucidate whether DRC levels are linked with plasma 25(OH)D levels. BC cases and controls were selected from our BC cohort. DRC levels were assessed in lymphocytes through the host-cell reactivation assay. 25(OH)D levels were measured using the UniCel DxI 600 Access Immunoassay System. BC cases (n = 91) showed higher 25(OH)D levels than the controls (n = 92) (p = 0.001). When stratifying BC cases and controls into low and high DRC categories, BC cases with low DRC (n = 74) had the highest 25(OH)D levels (p = 0.0001). A positive correlation between 25(OH)D and DRC levels was found for the controls (r = 0.215, p = 0.043) while a negative correlation was found for BC cases (r = −0.236, p = 0.026). Significant differences in 25(OH)D levels were observed when stratifying by molecular subtypes (p = 0.0025). Our study provides evidence of a link between 25(OH)D and DRC in BC along with a description of to how 25(OH)D levels vary across subtypes. The positive correlation observed in the control group suggests that 25(OH)D contributes differently to DRC levels once the malignancy is developed. Full article
