  • An Analysis of Benign Human Prostate Offers Insights Into the Mechanism
    www.nature.com/scientificreports OPEN An analysis of benign human prostate ofers insights into the mechanism of apocrine secretion Received: 12 March 2018 Accepted: 22 February 2019 and the origin of prostasomes Published: xx xx xxxx Nigel J. Fullwood 1, Alan J. Lawlor2, Pierre L. Martin-Hirsch3, Shyam S. Matanhelia3 & Francis L. Martin 4 The structure and function of normal human prostate is still not fully understood. Herein, we concentrate on the diferent cell types present in normal prostate, describing some previously unreported types and provide evidence that prostasomes are primarily produced by apocrine secretion. Patients (n = 10) undergoing TURP were prospectively consented based on their having a low risk of harbouring CaP. Scanning electron microscopy and transmission electron microscopy was used to characterise cell types and modes of secretion. Zinc levels were determined using Inductively Coupled Plasma Mass Spectrometry. Although merocrine secretory cells were noted, the majority of secretory cells appear to be apocrine; for the frst time, we clearly show high-resolution images of the stages of aposome secretion in human prostate. We also report a previously undescribed type of epithelial cell and the frst ultrastructural image of wrapping cells in human prostate stroma. The zinc levels in the tissues examined were uniformly high and X-ray microanalysis detected zinc in merocrine cells but not in prostasomes. We conclude that a signifcant proportion of prostasomes, possibly the majority, are generated via apocrine secretion. This fnding provides an explanation as to why so many large proteins, without a signal peptide sequence, are present in the prostatic fuid. Tere are many complications associated with the prostate from middle age onwards, including benign prostatic hyperplasia (BPH) and prostate cancer (PCa).

Emerging therapeutic targets in metastatic progression: a focus on breast cancer Zhuo Li and Yibin Kang* Department of Molecular Biology, Princeton University, Princeton, NJ, 08544, United States Abstract Metastasis is the underlying cause of death for the majority of breast cancer patients. Despite significant advances in recent years in basic research and clinical development, therapies that specifically target metastatic breast cancer remain inadequate, and represents the single greatest obstacle to reducing mortality of late-stage breast cancer. Recent efforts have leveraged genomic analysis of breast cancer and molecular dissection of tumor-stromal cross-talk to uncover a number of promising candidates for targeted treatment of metastatic breast cancer. Rational combinations of therapeutic agents targeting tumor-intrinsic properties and microenvironmental components provide a promising strategy to develop precision treatments with higher specificity and less toxicity. In this review, we discuss the emerging therapeutic targets in breast cancer metastasis, from tumor-intrinsic pathways to those that involve the host tissue components, including the immune system. Keywords Breast cancer; Metastasis; Targeted therapy; Tumor microenvironment; Immunotherapy 1. Introduction The overall 5-year survival rate for breast cancer currently stands at 90% — a dramatic improvement over the 63% survival rate in the early 1960s. When stratified by stage, the 5- year survival rates have increased to 99% for localized disease and 85% for regional advanced disease, a trend that can be attributed to early diagnoses and better treatment regimens.

  • (Eccrine and Apocrine Glands) During Childhood in Japanese, Especially on the PAS Positive Substance and Iron
    Histochemical Investigation on the Axillary Sweat Glands (Eccrine and Apocrine Glands) during Childhood in Japanese, especially on the PAS Positive Substance and Iron By Iwao Yasui and Hiroshi Kagemoto Department of Anatomy, School of Medicine, Keio University Shinjuku, Tokyo, Japan (Director : Prof. Dr. T. Taniguchi) Introduction The application of periodic acid to histochemical study on poly- saccharide was made for the first time by Hot c h k i s s, M c Man u s, Lillie et G r e co and Marches e. This histochemical method was called for short PAS method " (namely, Periodic Acid S c h i f f). 'Recently , a good deal of the histochemical studies regarding glyco- gen, mucopolysaccharide and other substances in the sweat glands have been made by such various scholars as Bunt in g, Wislocki and Dempsey (1948), Montagna, Chase and Lobitz (1952), Montagna, Chase and M e l a r a g n o (1951) and others, apply- ing the PAS method. On the other hand, studies on the iron reaction in the sweat glands have been numerously reported since H o m m a (1925)'s research on the axillary sweat glands by Turnbull reaction, that is, Klaar (1926), Herzenberg (1927), Moriyama (1927), Oono and Kinoshita (1927), Wosllard (1930), Richter (1933), Manca (1934), Way and Memmesheimer (1938), Yoshi- mura (1942), Nagamitsu (1941), Yoshihiro (1942a), Cavaz- zana (1947), Bunting, Wislocki and Dempsey (1948),Iwa- shige (1951),Montagna,Chase and Lobitz (1953) and others. Nevertheless, there have been no reports which give histochemical observation on the axillary sweat glands during childhood by age group.

  • A New Case of Hybrid Epidermoid and Apocrine Cyst
    Case Report A New Case of Hybrid Epidermoid and Apocrine Cyst Fulvia Serra 1,* and Gürkan Kaya 1,2,* 1 Department of Pathology, University Hospital of Geneva, 1205 Geneva, Switzerland 2 Department of Dermatology, University Hospital of Geneva, 1205 Geneva, Switzerland * Correspondence: [email protected] (F.S.); [email protected] (G.K.) Abstract: We described a new case of a hybrid epidermoid and apocrine cyst, known to be a rare histopathological entity. The cyst was located in the axillary region and completely excised, without complication. The diagnosis was made at the histological analysis, where we found a cystic lesion in the dermis, lined with both epidermoid and apocrine epithelium. Keywords: cutaneous cysts; hidrocystoma; hybrid epidermoid; apocrine cyst 1. Introduction Hybrid cutaneous cysts are little known lesions that can be overlooked by the patholo- gist. Inside this small and curious family, the hybrid epidermoid and apocrine cyst is rare and its origin and clinical significance are unknown. Here, we present a new case found in the axillary region in a middle-aged woman with no other known comorbidity. We discuss the histopathological findings, the hypothesis of its origin and we underline the difficulties that can be encountered in reporting this peculiar entity. 2. Case Report A 45-year-old woman with a previous history of two cysts in the right axillary region Citation: Serra, F.; Kaya, G. A New (never excised), admitted to surgically remove one of the two, which measured 0.95 cm. To Case of Hybrid Epidermoid and our knowledge, she does not have any prior disease.
