Abstract
Among the multiple properties exhibited by lactoferrin (Lf), its involvement in bone regeneration processes is of great interest at the present time. A series of in vitro and in vivo studies have revealed the ability of Lf to promote survival, proliferation and differentiation of osteoblast cells and to inhibit bone resorption mediated by osteoclasts. Although the mechanism underlying the action of Lf in bone cells is still not fully elucidated, it has been shown that its mode of action leading to the survival of osteoblasts is complemented by its mitogenic effect. Activation of several signalling pathways and gene expression, in an LRPdependent or independent manner, has been identified. Unlike the effects on osteoblasts, the action on osteoclasts is different, with Lf leading to a total arrest of osteoclastogenesis. Due to the positive effect of Lf on osteoblasts, the potential use of Lf alone or in combination with different biologically active compounds in bone tissue regeneration and the treatment of bone diseases is of great interest. Since the bioavailability of Lf in vivo is poor, a nanotechnology- based strategy to improve the biological properties of Lf was developed. The investigated formulations include incorporation of Lf into collagen membranes, gelatin hydrogel, liposomes, loading onto nanofibers, porous microspheres, or coating onto silica/titan based implants. Lf has also been coupled with other biologically active compounds such as biomimetic hydroxyapatite, in order to improve the efficacy of biomaterials used in the regulation of bone homeostasis. This review aims to provide an up-to-date review of research on the involvement of Lf in bone growth and healing and on its use as a potential therapeutic factor in bone tissue regeneration.

Immunoexpression of lactoferrin in triple-negative breast cancer patients: A proposal to select a less aggressive subgroup. Oncol Lett 2017; 13:3205-3209.

Abstract
Triple-negative breast cancer (TNBC) indicates a subset of breast carcinomas that does not express estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor-2 (HER2). According to the literature, TNBCs are aggressive tumors, characterized by a high incidence of recurrence and a high risk of disease progression. Lactoferrin (LF) is a single-chain, iron-binding glycoprotein of ~700 amino acids, which is involved in a wide range of biological activities, including iron-trafficking and carcinogenesis. The present study aimed to assess LF expression in human TNBC samples and the possible correlation with clinico-pathological parameters associated with biological aggressiveness. LF immunohistochemical expression was investigated in formalin-fixed, paraffin-embedded samples of human TNBC. Cases were analyzed according to an intensity distribution (ID) score, and only those showing an ID score of >2 were considered as positive for LF. LF immunostaining was encountered in 26.15% cases. A significant correlation was found between LF expression and a low Ki-67 labeling index (P=0.040), the absence of recurrence (P=0.010) and alive status (P=0.020). LF may assist in identifying a subset of TNBC with less aggressive biological behavior. The meaning of LF expression in TNBC remains unclear and is controversial. The present findings indicated that LF expression is correlated with a low growth fraction in these tumors. Thus, it is possible that the inhibition of the LF axis may be a valid therapeutic target for TNBC, and this should be confirmed by future studies.

Abstract
Although the immunohistochemical presence of lactoferrin (LF) in pathological neoplastic bone and cartilage samples has previously been studied, no data concerning the distribution of LF in bone metastases of cancers that have originated from different organs are available at present. Consequently, using a monoclonal antibody, we have investigated the immunohistochemical LF pattern in 50 formalin-fixed and paraffin-embedded samples of human bone metastases and their corresponding primary carcinoma tumours (breast, 8; prostate, 4; kidney, 4; lung, 3; colon-rectum, 2 and uterus, 4). Quantification of LF immunoreactivity was performed using an intensity distribution (ID) score. LF immuno staining with a variable ID score was encountered in 11/25 (44%) metastatic lesions. In particular, the LF immunoreactivity was identified with a percentage ranging from 50 to 75% of bone metastases due to prostatic, renal, uterine and colorectal carcinomas; the positivity decreased in breast carcinomas (37.5%) and was completely absent in lung cancers. No differences in the LF-ID score were observed between primary and metastatic neoplastic localisations. Additionally, no correlations were identified between LF immunoexpression and the other parameters tested, including the age and gender of patients. Regardless of the mechanism of action of LF in human malignant tumours, we identified LF immunohistochemical reproducibility at primary and metastatic sites. Therefore, we hypothesise that the presence of LF in native neoplastic carcinomatous clones is maintained in secondary bone metastatic deposits.

Abstract
Lactoferrin (LF) is an iron-binding glycoprotein of the transferrin family, today known to have multifunctional physiological activities. In humans, under normal conditions, LF has been found in blood, mucosal secretions, gastrointestinal fluids, urine and mostly in milk and colostrum. The first pioneering immunohistochemical report about LF distribution in human tissues dated in 1978; successively, many studies have been performed to analyze the LF immunohistochemical pattern in different normal and neoplastic tissues. In this review, we present data from literature concerning the evidence of LF in tumors together with those by us obtained during more than 25 years; the immunohistochemical applications to human neoplastic tissues have been done to investigate the LF pathogenetic role as well as its activity in cancer. After a systematic analysis of LF immunoreactivity in different human districts, a possible explanation for its presence and function has been modulated for each site or tissue, according to experimental evidences obtained either by in vivo as well as by in vitro studies.

Abstract
Lf (lactoferrin) is an 80-kDa iron-binding protein, which has been suggested to promote bone growth in murine models. In view of this, we aimed to analyse the immunohistochemical distribution of Lf in human embryonal and fetal bone and cartilaginous tissues at different gestational weeks in order to evaluate whether a role for this protein might be proposed also in human osteogenesis. Bone and cartilaginous specimens were taken at autopsy from 25 fetuses (8-34 weeks of gestation). Ten samples of human adult bone and cartilage were also submitted to the immunohistochemical procedures. Sections, 4-microm thick, were cut from formalin-fixed paraffin-embedded tissue blocks and stained with a monoclonal antibody against human Lf, following antigen retrieval procedures. Lf immunoreactivity was mainly localized in the mesenchymal cells forming the periosteum as well as in chondroblasts at the eighth gestational week; a strong Lf immunoexpression in immature osteocytes and osteoblasts was noted up to the 18th gestation week, with a considerable decrease by the 24th week. No Lf expression was found in any bone area after the 30th and up to the 34th week of gestation. Our data seem to suggest an important role for Lf as a bone growth regulator in the early phases of the human endochondral ossification, with an anabolic action similar to that previously reported in cell culture lines and in animal models.

Abstract
By immunohistochemistry, lactoferrin (LF) has been extensively investigated in human neoplastic tissues; moreover, LF is able to promote bone growth in a murine model. Until now, no systematic studies on human osteocartilagineous fetal samples have been performed in comparison to corresponding neoplastic specimens to verify if LF may represent an oncofetal marker in this field of pathology. By a monoclonal antibody (clone 1A1; Biodesign International; w.d. 1:75) the distribution pattern of LF in bones of 25 human fetal tissues (8-34 gestation weeks), 10 adults (47-82 years) and 30 cartilage as well as 27 bone tumours (9-76 years) was analyzed. LF was encountered in 23/57 cases of osteocartilagineous tumors and namely in 10/10 giant cell tumours, 5/7 osteoid osteomas, 3/3 chondroblastomas, 3/3 chondromyxoid fibromas, 1/1 myeloma, 1/1 adamantinoma. No LF immunoexpression was detected in osteosarcomas, chondrosarcomas, ossifying fibromas, osteochondroma and enchondromas. In embryo-fetal tissues, LF immunoreactivity was localized in mesenchymal cells as well as in chondroblasts at the 8th gestational week and in immature osteocytes and osteoblasts up to the 18th gestation week, with a considerable decrease by the 24th week. No LF expression was found in any bone district since the 30th and up to the 34th week of gestation as well as in corresponding adult samples. Our findings indicate a role for LF as a bone growth regulator in the early phases of the human endochondral ossification, although the hypothesis of LF as oncofetal marker appears questionable in bone tumours.
