Abstract
Cell Penetrating Peptides -CPPs- are short aminoacidic stretches present in proteins that have the ability to translocate the plasma membrane and facilitate delivery of various molecules. They are usually rich in basic residues, and organized as alpha helices. NF-Y is a transcription factor heterotrimer formed by two Histone Fold Domain -HFD- subunits and the sequence-specific NF-YA. NF-YA possesses two α-helices rich in basic residues. We show that it efficiently enters cells at nanomolar concentrations in the absence of carrier peptides. Mutagenesis identified at least two separate CPPs in the A1 and A2, which overlap with previously identified nuclear localization signals (NLS). The half-life of the transduced protein is short in human cancer cells, longer in mouse C2C12 myoblasts. The internalized NF-YA is capable of trimerization with the HFD subunits and binding to the target CCAAT box. Functionality is further suggested by protein transfection in C2C12 cells, leading to inhibition of differentiation to myotubes. In conclusion, NF-YA contains CPPs, hinting at novel -and unexpected- properties of this subunit.

Abstract
The past decade has seen incredible advances in the field of stem cell biology that have greatly improved our understanding of development and provided important insights into pathological processes. Transcription factors (TFs) play a central role in mediating stem cell proliferation, quiescence, and differentiation. One TF that contributes to these processes is Nuclear Factor One X (NFIX). Recently, NFIX activity has been shown to be essential in multiple organ systems and to have important translational impacts for human health. Here, we describe recent studies showing the contribution of NFIX to muscle development and muscular dystrophies, hematopoiesis, cancer, and neural stem cell biology, highlighting the importance of this knowledge in the development of therapeutic targets.

Abstract
OBJECTIVES Risk adjustment is a widely used tool for health expenditure prediction and control. Early approaches for estimating health expenditure were based on patient demographic variables alone, whereas more recent models incorporate patient information, such as chronic medical conditions, clinical diagnoses, and self-reported health status. Many studies have investigated the health expenditure predictive capacity of single demographic, morbidity, or health-related quality of life measures, but the best models prove to be those that include them all. The aim of this study was to develop an index that combines measures of perceived health and disease severity and to compare its efficacy in predicting health expenditure with that of the measures taken individually. STUDY DESIGN This is a linked cross-sectional study. METHODS In 2009 and 2010, the health-related quality of life questionnaire SF-36 (8 scales, two indices: Physical Component Summary [PCS] and Mental Component Summary [MCS]) was distributed to 886 patients of general practitioners in the Province of Siena, Italy. Severity of diseases was calculated for each patient using the Charlson Index (CH-I) and Cumulative Illness Rating Scale Severity Index (CIRS-SI). Siena Local Health Unit 2012 data on health expenditure were obtained for each patient. Multivariate linear regression was applied to test the performance of severity (CH-I, CIRS-SI) and perceived health (PCS and MCS) measures in predicting health expenditure. The indexes that predicted health expenditure best were then combined in a new tool, and its expenditure predictive capacity was tested. RESULTS The best health expenditure predictors proved to be PCS and SI (R2 = 0.15 and R2 = 0.17, respectively). When combined in a new index (PCS-SI), better predictive capacity of health expenditure was obtained than with the two single measures separately (R2 = 0.19). CONCLUSIONS A multidimensional indicator proved to be a better predictor of healthcare expenditure than single health measures.

Abstract
Strength, power and muscular endurance tests have been developed as means of assessing people's physical abilities. However, testing may be expensive or time consuming. A method to reduce the time of physical assessment could be to use predictive algorithms for indirect assessment. The aim of this study will be to determine a relationship between strength, power and muscular endurance in order to identify predictors for an easier and faster assessment. 33 male strength-trained participants (22.8 ± 4.6 years, 172.5 ± 6.7 cm, 68.0 ± 10.6 kg) performed a single pull-up (SPU) and a single push-up (SPH) and a set of pull-ups (EPU) and push-ups (EPH) to exhaustion. The participants were divided into three sub-groups according to their training experience. Force(F), Power(P), Velocity(V) and relative power(R-P), extracted from an accelerometer (500 Hz), were compared between groups (ANOVA) and a subsequent linear regression analysis was performed to identify predictors of the performance measures. The regression models were able to explain 61% of the variance with the EPU as dependent variable and the V of the SPU as independent variable and 68% of the variance with the EPH as dependent variable and EPU as independent variable. In addition, increased performance measures were found according to training experience, in particular regarding muscular endurance of both the EPU and EPH (p < 0.001 and p < 0.01, respectively). A significant effect of training experience was also present for the V of the SPU (p < 0.001). The results indicate that a relation between muscular endurance and velocity is present. The generated equations allow to estimate both the number of EPH and EPU from a SPU. The equations may be helpful to reduce the time of assessment for upper body physical evaluation.

Abstract
Aims and background Ovarian carcinoma remains confined to the peritoneal cavity for the greater part of its natural history, so intraperitoneal (IP) administration of chemotherapy could result in greater total drug exposure of the tumor and minimize systemic antiblastic drug side effects. The aim of this study was to evaluate the therapeutic efficacy and toxic effects of intraperitoneal mitoxanthrone in patients affected by ovarian carcinoma with macroscopic absence of disease or minimal residual disease. Methods Ten patients were enrolled (stage II and III) who had been previously treated with neoadjuvant systemic chemotherapy (CDDP or CBDCA + CTX) and radical surgery resulting in macroscopic absence of disease or minimal residual disease (<1 cm). Mitoxanthrone (25 mg/m2) was instilled in 2 liters of normal saline every four weeks for 2-4 cycles. Results A total of 26 courses was administered; two patients discontinued IP therapy, one for chemoperitonitis and another for bowel perforation requiring catheter removal. Of the 10 patients receiving IP chemotherapy, 7 are alive at 5 years from radical surgery, and 3 had relapses at 13, 14 and 57 months, respectively, from radical surgery. Conclusions Intraperitoneal mitoxanthrone appears to be an effective second-line therapy in ovarian cancer; it is well tolerated as far as toxic effects are concerned, allowing cost reduction and improved patient compliance. For those cases requiring a limited number of peritoneal accesses traditional percutaneous systems have a more favorable cost/benefit ratio.

Abstract
The formation and activity of mammalian tissues entail finely regulated processes, involving the concerted organization and interaction of multiple cell types. In recent years the prospective isolation of distinct progenitor and stem cell populations has become a powerful tool in the hands of developmental biologists and has rendered the investigation of their intrinsic properties possible. In this protocol, we describe how to purify progenitors with different lineage history and degree of differentiation from embryonic and fetal skeletal muscle by fluorescence-activated cell sorting (FACS). The approach takes advantage of a panel of murine strains expressing fluorescent reporter genes specifically in the myogenic progenitors. We provide a detailed description of the dissection procedures and of the enzymatic dissociation required to maximize the yield of mononucleated cells for subsequent FACS-based purification. The procedure takes ~6–7 h to complete and allows for the isolation and the subsequent molecular and phenotypic characterization of developmental myogenic progenitors.

Abstract
Duchenne muscular dystrophy (DMD) is a lethal muscle-wasting disease currently without cure. We investigated the use of the PiggyBac transposon for full-length dystrophin expression in murine mesoangioblast (MABs) progenitor cells. DMD murine MABs were transfected with transposable expression vectors for full-length dystrophin and transplanted intramuscularly or intra-arterially into mdx/SCID mice. Intra-arterial delivery indicated that the MABs could migrate to regenerating muscles to mediate dystrophin expression. Intramuscular transplantation yielded dystrophin expression in 11%-44% of myofibers in murine muscles, which remained stable for the assessed period of 5 months. The satellite cells isolated from transplanted muscles comprised a fraction of MAB-derived cells, indicating that the transfected MABs may colonize the satellite stem cell niche. Transposon integration site mapping by whole-genome sequencing indicated that 70% of the integrations were intergenic, while none was observed in an exon. Muscle resistance assessment by atomic force microscopy indicated that 80% of fibers showed elasticity properties restored to those of wild-type muscles. As measured in vivo, transplanted muscles became more resistant to fatigue. This study thus provides a proof-of-principle that PiggyBac transposon vectors may mediate full-length dystrophin expression as well as functional amelioration of the dystrophic muscles within a potential autologous cell-based therapeutic approach of DMD.

Abstract
We present a pilot study on the effects of milk protein fractions [αS1-casein (CN), αS2-CN, κ-CN, β-CN, and a mix of α-lactalbumin (α-LA) and β-lactoglobulin (β-LG)] from different animal species (bovine, ovine, and caprine) on pro- and anti-inflammatory cytokines and oxidative status in cultured peripheral blood mononuclear cells from children with generalized epilepsy. Peripheral blood mononuclear cells (PBMC) were obtained by density gradient from blood of 10 children with generalized epilepsy (5 males; mean age 33.6 ± 5.4 mo) and 10 controls (5 males; mean age 35.6 ± 6.8 mo). Children with epilepsy were grouped according to cytokine levels as follows: children with epilepsy having low levels of cytokines not different from those of control children (LL-EC); children with epilepsy having cytokine levels at least 5-fold higher (medium levels) than those of control children (ML-EC); and children with epilepsy having cytokine levels at least 10-fold higher (high levels) than those of control children (HL-EC). The production of tumor necrosis factor-α (TNF-α), IL-10, IL-6, and IL-1β was studied in cultured PBMC incubated with αS1-CN, αS2-CN, κ-CN, β-CN, and a mix of α-LA and β-LG from bovine, caprine, and ovine milks. The levels of reactive oxygen and nitrogen species (ROS/RNS) and catalase activity were assessed in cultured supernatant. In the HL-EC group, β-CN from small ruminant species (ovine and caprine) induced the highest levels of TNF-α, whereas PBMC incubated with αS2-CN from ovine milk and the mix of β-LG and α-LA from all tested milk species had the lowest levels of TNF-α. Within the HL-EC group, production of IL-1β was higher for bovine and ovine αS2-CN fractions and lower for caprine and ovine β-CN and κ-CN. In the HL-EC group, IL-6 was higher in cultured PBMC incubated with αS2-CN from bovine and ovine milk than from caprine milk. The cytokine IL-10 did not differ among milking species. The highest levels of ROS/RNS were found after incubation of PBMC with the β-CN fraction in bovine milk. Catalase activity was higher in PBMC cultured with β-CN isolated from bovine and caprine milk and with αS1-CN from ovine milk.

Abstract
Transferring large or multiple genes into primary human stem/progenitor cells is challenged by restrictions in vector capacity, and this hurdle limits the success of gene therapy. A paradigm is Duchenne muscular dystrophy (DMD), an incurable disorder caused by mutations in the largest human gene: dystrophin. The combination of large-capacity vectors, such as human artificial chromosomes (HACs), with stem/progenitor cells may overcome this limitation. We previously reported amelioration of the dystrophic phenotype in mice transplanted with murine muscle progenitors containing a HAC with the entire dystrophin locus (DYS-HAC). However, translation of this strategy to human muscle progenitors requires extension of their proliferative potential to withstand clonal cell expansion after HAC transfer. Here, we show that reversible cell immortalisation mediated by lentivirally delivered excisable hTERT and Bmi1 transgenes extended cell proliferation, enabling transfer of a novel DYS-HAC into DMD satellite cell-derived myoblasts and perivascular cell-derived mesoangioblasts. Genetically corrected cells maintained a stable karyotype, did not undergo tumorigenic transformation and retained their migration ability. Cells remained myogenic in vitro (spontaneously or upon MyoD induction) and engrafted murine skeletal muscle upon transplantation. Finally, we combined the aforementioned functions into a next-generation HAC capable of delivering reversible immortalisation, complete genetic correction, additional dystrophin expression, inducible differentiation and controllable cell death. This work establishes a novel platform for complex gene transfer into clinically relevant human muscle progenitors for DMD gene therapy.

Abstract
The evidence of lymphocytopenia has been demonstrated to predict a poor prognosis in terms of survival in advanced cancer patients. This finding is not surprising because of the fundamental role of lymphocytes in mediating tumor cell destruction. Despite the importance of lymphocytes in the pathogenesis of cancer, there are only few data about the profile and the function of lymphocytes during the various antitumor therapies, and in particular the relation between lymphocyte pretreatment number and response to chemotherapy remains to be established. The present study was performed to evaluate whether the evidence of lymphocytopenia before the onset of treatment may influence the efficacy of chemotherapy in metastatic cancer patients affected by the most frequent tumor types. The study included 183 patients (lung cancer: 89; colorectal cancer: 63; breast cancer: 31), 95 of whom had been previously treated with chemotherapy. The chemotherapeutic regimens consisted of oxaliplatin plus 5-fluorouracil and folates in untreated colorectal cancer, weekly irinotecan in pretreated colorectal cancer, cisplatin plus gemcitabine or etoposide in untreated lung cancer, weekly vinorelbine in pretreated lung cancer, and taxotere in breast cancer patients who had been previously treated with anthracyclines. Lymphocyte count was considered to be abnormally low for values below 1500/mm3. Lymphocytopenia was found in 79/183 (43%) patients, without any significant differences in relation to tumor histology. A complete response (CR) was achieved in 6/104 patients with a normal lymphocyte count and in none of the 79 lymphocytopenic patients. A partial response (PR) was obtained in 39 patients with a normal lymphocyte count and in only eight patients with a low lymphocyte count prior to therapy. Therefore, irrespective of the type of chemotherapy, the objective tumor response rate (CR + PR) in lymphocytopenic patients was significantly lower than in patients with normal pretreatment lymphocyte counts (8/79 vs 45/104; p<0. 001). This study shows that the evidence of lymphocytopenia prior to chemotherapy is associated with a lower efficacy of treatment in terms of objective tumor regression rates in patients with metastatic solid tumors, and suggests that the action of chemotherapy may depend at least in part on an interaction with the antitumor immunity. Pretreatment lymphocyte count may represent a new, simple biological marker to be taken into consideration by oncologists in the chemotherapeutic treatment of metastatic cancer.

Abstract
Lymphocytopenia is one of the main toxicities of radiotherapy and its severity is related to the irradiation dose. The occurrence of lymphocytopenia depends on the body site of radiotherapy; it is most pronounced with pelvic irradiation, whereas the effect of brain irradiation on the lymphocyte count is to be elucidated. This preliminary study was performed to evaluate changes in lymphocyte number occurring during brain irradiation in cancer patients with brain metastases. The study included 50 patients who received brain radiotherapy for single or multiple brain metastases at a total dose of 30 Gy. Overall, no significant changes in mean lymphocyte number occurred during brain radiotherapy. However, when lymphocyte variations were assessed in relation to the clinical response of brain metastases, a significant increase in the mean number of lymphocytes was found in patients who achieved objective regression of brain metastases on brain irradiation. The mean lymphocyte number decreased in nonresponding patients, albeit without a statistically significant difference with respect to the pretreatment values. The results of this study show that the efficacy of radiotherapy in the treatment of brain metastases is associated with a significant increase in mean lymphocyte number. Therefore, evidence of brain irradiation-induced lymphocytosis may predict the efficacy of radiotherapy.

Abstract
It has been shown that each manipulation of the mammary region, including breast surgery, may stimulate prolactin secretion. However, it has also been observed that in more than 50% of breast cancer patients surgical removal of the tumor is not followed by enhanced prolactin secretion. This might be indicative of an altered psychoneuroendocrine control of the mammary gland, which could lead to the onset of more biologically aggressive breast cancer. In fact, surgery-induced hyperprolactinemia has been proven to be associated with a better prognosis in terms of survival in node-negative breast cancer patients. The present study was performed to investigate the impact of postoperative hyperprolactinemia on the disease-free survival (DFS) of breast cancer patients with axillary node involvement. The study included 100 consecutive node-positive breast cancer patients who were followed for at least 10 years. Surgery-induced hyperprolactinemia occurred in 45/100 (45%) patients without any significant correlation with the main prognostic variables including number of involved nodes and ER status. The two groups of patients received the same adjuvant therapies. After a median follow-up of 151 months, the recurrence rate in patients with surgery-induced hyperprolactinemia was significantly lower than in patients with no postoperative hyperprolactinemia (23/45 vs 43/55, p<0.01). Moreover, DFS was significantly longer in hyperprolactinemic patients than in patients who had no enhanced secretion of prolactin postoperatively. In agreement with the results described previously in node-negative breast cancer, our study demonstrates the favorable prognostic significance of surgery-induced hyperprolactinemia in terms of DFS duration also in breast cancer patients with axillary node involvement, independent of the other well-known prognostic variables, thereby confirming that the psychoneuroendocrine status of cancer patients may influence the prognosis of their disease.

RhoA and ERK signalling regulate the expression of the myogenic transcription factor Nfix. Development 2018; 145:dev.163956.

Abstract
The transcription factor Nfix belongs to the nuclear factor one family and has an essential role in prenatal skeletal muscle development, where it is a master regulator of the transition from embryonic to foetal myogenesis. Recently, Nfix was shown to be involved in adult muscle regeneration and in muscular dystrophies. Here, we investigated the signalling that regulates Nfix expression, and show that JunB, a member of the AP-1 family, is an activator of Nfix, which then leads to foetal myogenesis. Moreover, we demonstrate that their expression is regulated through the RhoA/ROCK axis, which maintains embryonic myogenesis. Specifically, RhoA and ROCK repress ERK kinase activity, which promotes JunB and Nfix expression. Notably, the role of ERK in the activation of Nfix is conserved post-natally in satellite cells, which represent the canonical myogenic stem cells of adult muscle. As lack of Nfix in muscular dystrophies rescues the dystrophic phenotype, the identification of this pathway provides an opportunity to pharmacologically target Nfix in muscular dystrophies.

Abstract
Muscular dystrophies (MDs) are still incurable heterogeneous diseases, characterized by muscle wasting, replacement by fibrotic tissue, and increasing weakness, which in severe cases, such as Duchenne MD, lead to premature death. MDs are due to mutations encompassing different dystrophin-glycoprotein complex (DGC) genes, which code for structural proteins that anchor the cytoskeleton to the extracellular matrix, thus conferring myofiber stability. All mutations destabilizing this complex result in different MD forms, with varying levels of severity. Independently of the genetic defect, MDs share common hallmarks, characterized by continuous cycles of muscle degeneration, due to lack of structural support during contraction, followed by regeneration cycles by satellite cells (SCs), the canonical myogenic stem cells of adult muscle. However, dystrophic SCs generate new fibres which are also prone to degeneration so that, after many cycles of degeneration/regeneration, this cell population is exhausted and muscle is replaced by connective and adipose tissue. At this stage, any therapeutic intervention is likely to fail.

Abstract
BACKGROUND Colorectal cancer (CRC) is the 2nd most common cancer in women worldwide. In Italy, only 50% of people invited to get the Fecal Occult Blood Test (FOBT) decided to do it. Women's participation in breast and cervical screening is, instead, very high (>70%). The aim of our study was to investigate the beliefs, the feelings and the psychological factors that could influence the participation of women in CRC screening. METHODS We conducted a cross sectional study, in the Hospital of Siena, Central Italy, in 2011. We administered a questionnaire to 507 women of all ages, who attended mammography or clinical breast examination. The adherence to CRC screening was analyzed only in the group of 207 older women (age >50 years). We performed descriptive, bivariate and logistic regression analysis to identify whether an association was present between participant characteristics, willingness and adherence to screening. RESULTS Family history of colorectal cancer (OR 4.3; p<0.007) and the General Practitioner's advice (OR: 3.4; p<0.003) were associated with a greater adherence to screening (colonoscopy). The embarrassment was another factor related to colonoscopy compliance (OR: 0.34; p<0.016). CONCLUSION Family history of CRC, pain or embarassment and GP's advice are the factors that correlated more strongly (positively or negatively) with adherence to colorectal cancer screening. These elements should be further analyzed to choose the best solution to improve the adherence in campaigns on colorectal cancer.

Abstract
Inflammation and tissue regeneration follow tissue damage, but little is known about how these processes are coordinated. Tirone et al. show that alternative redox forms of high mobility group box 1 (HMGB1), the “alarmin” signal released by damaged cells, trigger inflammation or tissue repair after injury by interacting with distinct receptors and that a nonoxidizable HMGB1 mutant promotes regeneration without exacerbating inflammation. Inflammation and tissue regeneration follow tissue damage, but little is known about how these processes are coordinated. High Mobility Group Box 1 (HMGB1) is a nuclear protein that, when released on injury, triggers inflammation. We previously showed that HMGB1 with reduced cysteines is a chemoattractant, whereas a disulfide bond makes it a proinflammatory cytokine. Here we report that fully reduced HMGB1 orchestrates muscle and liver regeneration via CXCR4, whereas disulfide HMGB1 and its receptors TLR4/MD-2 and RAGE (receptor for advanced glycation end products) are not involved. Injection of HMGB1 accelerates tissue repair by acting on resident muscle stem cells, hepatocytes, and infiltrating cells. The nonoxidizable HMGB1 mutant 3S, in which serines replace cysteines, promotes muscle and liver regeneration more efficiently than the wild-type protein and without exacerbating inflammation by selectively interacting with CXCR4. Overall, our results show that the reduced form of HMGB1 coordinates tissue regeneration and suggest that 3S may be used to safely accelerate healing after injury in diverse clinical contexts.

Nfix Induces a Switch in Sox6 Transcriptional Activity to Regulate MyHC-I Expression in Fetal Muscle. Cell Rep 2017; 17:2354-2366.

Abstract
Sox6 belongs to the Sox gene family and plays a pivotal role in fiber type differentiation, suppressing transcription of slow-fiber-specific genes during fetal development. Here, we show that Sox6 plays opposite roles in MyHC-I regulation, acting as a positive and negative regulator of MyHC-I expression during embryonic and fetal myogenesis, respectively. During embryonic myogenesis, Sox6 positively regulates MyHC-I via transcriptional activation of Mef2C, whereas during fetal myogenesis, Sox6 requires and cooperates with the transcription factor Nfix in repressing MyHC-I expression. Mechanistically, Nfix is necessary for Sox6 binding to the MyHC-I promoter and thus for Sox6 repressive function, revealing a key role for Nfix in driving Sox6 activity. This feature is evolutionarily conserved, since the orthologs Nfixa and Sox6 contribute to repression of the slow-twitch phenotype in zebrafish embryos. These data demonstrate functional cooperation between Sox6 and Nfix in regulating MyHC-I expression during prenatal muscle development. Sox6 has opposite roles in MyHC-I regulation during embryonic and fetal myogenesis In embryonic muscle, Sox6 enhances MyHC-I expression via regulation of Mef2C In fetal muscle, Nfix is required for Sox6-mediated repression of MyHC-I The Sox6 and Nfixa orthologs cooperate in repressing smyhc1 in zebrafish
