    Abstract Background: Dormancy is widespread in both multicellular and unicellular organisms. Among diatoms, unicellular microalgae at the base of all aquatic food webs, several species produce dormant cells (spores or resting cells) that can withstand long periods of adverse environmental conditions.
    Results: We present the first gene expression study during the process of spore formation induced by nitrogen depletion in the marine planktonic diatom Chaetoceros socialis. In this condition, genes related to photosynthesis and nitrate assimilation, including high-affinity nitrate transporters (NTRs), were downregulated. While the former result is a common reaction among diatoms under nitrogen stress, the latter seems to be exclusive of the spore-former C. socialis. The upregulation of catabolic pathways, such as tricarboxylic acid cycle, glyoxylate cycle and fatty acid beta-oxidation, suggests that this diatom could use lipids as a source of energy during the process of spore formation. Furthermore, the upregulation of a lipoxygenase and several aldehyde dehydrogenases (ALDHs) advocates the presence of oxylipin-mediated signaling, while the upregulation of genes involved in dormancy-related pathways conserved in other organisms (e.g. serine/threonine-protein kinases TOR and its inhibitor GATOR) provides interesting avenues for future explorations.
    Conclusions: Our results demonstrate that the transition from an active growth phase to a resting one is characterized by marked metabolic changes and provides evidence for the presence of signaling pathways related to intercellular communication.

    Abstract Early life exposure to Endocrine Disruptor Chemicals (EDCs), such as the organophosphate pesticide Chlorpyrifos (CPF), affects the thyroid activity and dependent process, including the glucose metabolism. The damage of thyroid hormones (THs) as a mechanism of action of CPF is underestimated because the studies rarely consider that TH levels and signaling are customized peripherally. Here, we investigated the impairment of metabolism/signaling of THs and lipid/glucose metabolism in the livers of 6-month-old mice, developmentally and lifelong exposed to 0.1, 1, and 10 mg/kg/die CPF (F1) and their offspring similarly exposed (F2), analyzing the levels of transcripts of the enzymes involved in the metabolism of T3 (

    Abstract Sleep-disordered breathing (SDB) is a group of sleep-related breathing disorders which includes obstructive sleep apnea (OSA), central sleep apnea (CSA), and obesity hypoventilation syndrome (OHS). OHS is characterized by a combination of obesity, daytime hypercapnia and hypoxemia, and sleep-disordered breathing without other known hypoventilation causes, such as severe obstructive or restrictive parenchymal lung disease, kyphoscoliosis, severe hypothyroidism, neuromuscular disease, or congenital central hypoventilation syndrome. Four hundred ninety potentially eligible references were identified; of these, 462 abstracts or full texts were excluded because they did not fulfil inclusion criteria. We reviewed the full text of the remaining 38 papers which fulfilled the inclusion criteria. The role of gender in SDB and particularly in OHS is not well known. In general, the diseases are under-recognized in women and only a few studies have reported the impact of gender on clinical presentation and treatment outcome. On the other hand, there is often a delay in diagnosing these diseases in women as compared to men; therefore, they are often more advanced when diagnosed in women. Better understanding and clinical awareness of the higher OHS prevalence in postmenopausal women may lead to earlier diagnosis and a more timely and appropriate treatment. Further studies are needed to assess the prevalence of OHS in women, the effect of menopause on OHS, and the increased risk of OHS, which will hopefully lead to optimizing OHS patient care.

    Abstract Chronic obstructive pulmonary disease (COPD) has traditionally been viewed as a disease affecting older men with a history of smoking, while being neglected and under-diagnosed in women. This scenario has changed in recent years as there has been a steady increase in COPD prevalence and mortality rates in women. The increased prevalence of COPD among women is likely attributable to several factors including the increased rates of cigarette smoking observed in women during recent years, exposure to indoor air pollution as well as increased occupational exposures since women take on previously male-dominated occupational roles related to risk exposure. In this review we have analyzed the difference in COPD phenotypes and features related to gender difference.

The damage of thyroid hormones (THs) as a mechanism of action of CPF is underestimated because the studies rarely consider that TH levels and signaling are customized peripherally. Here, we investigated the impairment of metabolism/signaling of THs and lipid/glucose metabolism in the livers of 6-month-old mice, developmentally and lifelong exposed to 0.1, 1, and 10 mg/kg/die CPF (F1) and their offspring similarly exposed (F2), analyzing the levels of transcripts of the enzymes involved in the metabolism of T3 ( Dio1 ), lipids ( Fasn , Acc1 ), and glucose ( G6pase , Pck1 ). Both processes were altered only in F2 males, affected by hypothyroidism and by a systemic hyperglycemia linked to the activation of gluconeogenesis in mice exposed to 1 and 10 mg/kg/die CPF. Interestingly, we observed an increase in active FOXO1 protein due to a decrease in AKT phosphorylation, despite insulin signaling activation. Experiments in vitro revealed that chronic exposure to CPF affected glucose metabolism via the direct modulation of FOXO1 activity and T3 levels in hepatic cells. In conclusion, we described different sex and intergenerational effects of CPF exposure on the hepatic homeostasis of THs, their signaling, and, finally, glucose metabolism. The data points to FOXO1-T3-glucose signaling as a target of CPF in liver.

    Abstract Coronavirus Disease-2019 (COVID-19) is the worst worldwide pandemic with more than 12,000,000 cases and 560,000 deaths until 14th July 2020. Men were more infected by COVID-19 than women, and male subjects with underlying conditions, including diabetes, hypertension, and cardiovascular diseases developed a severe form of the affection, with increased mortality rate. Many factors can contribute to the disparity in disease outcomes, such as hormone-specific reaction and activity of X-linked genes, which modulate the innate and adaptive immune response to virus infection. Until now, only the Remdesivir was approved by FDA (Food Drug Administration) for COVID-19 treatment, although several clinical trials are ongoing worldwide also on other drugs. In this review, we analyzed published studies on several drugs (chloroquine or hydroxychloroquine, remdesivir, favipiravir, lopinavir-ritonavir in combination, tocilizumab, plasma, and immunoglobulins) with some efficacy to COVID-19 in humans, and evaluated if there were a gender analysis of the available data. In our opinion, it is essential to report data about COVID-19 disaggregated by sex, age, and race, because the knowledge of gender differences is fundamental to identify effective and customized treatments to reduce hospitalizations, admissions to intensive care units, and mortality.

    Abstract Vaccination is one of the greatest achievements of public health. Vaccination programs have contributed to the decline in mortality and morbidity of various infectious diseases. This review aims to investigate the impact of sex/gender on the vaccine acceptance, responses, and outcomes. The studies were identified by using PubMed, until 30th June 2020. The search was performed by using the following keywords: SARS-CoV-2, COVID-19, gender, sex, vaccine, adverse reaction. Clinical trials, retrospective and prospective studies were included. Studies written in languages other than English were excluded. Studies were included if gender differences in response to vaccination trials were reported. All selected studies were qualitatively analyzed. Innate recognition and response to viruses, as well as, adaptive immune responses during viral infections, differ between females and males. Unfortunately, a majority of vaccine trials have focused on healthy people, with ages between 18 to 65 years, excluding the elderly, pregnant women, post-menopausal female and children. In conclusion, it is apparent that the design of vaccines and vaccine strategies should be sex-specific, to reduce adverse reactions in females and increase immunogenicity in males. It should be mandatory to examine sex-related variables in pre-clinical and clinical vaccine trials, such as their crucial role for successful prevention of pandemic COVID-19.

    Abstract Because of their importance as chemical mediators, the presence of a rich and varied family of lipoxygenase (LOX) products, collectively named oxylipins, has been investigated thoroughly in diatoms, and the involvement of these products in important processes such as bloom regulation has been postulated. Nevertheless, little information is available on the enzymes and pathways operating in these protists. Exploiting transcriptome data, we identified and characterized a LOX gene, PaLOX, in Pseudo-nitzschia arenysensis, a marine diatom known to produce different species of oxylipins by stereo- and regio-selective oxidation of eicosapentaenoic acid (EPA) at C12 and C15. PaLOX RNA interference correlated with a decrease of the lipid-peroxidizing activity and oxylipin synthesis, as well as with a reduction of growth of P. arenysensis. In addition, sequence analysis and structure models of the C-terminal part of the predicted protein closely fitted with the data for established LOXs from other organisms. The presence in the genome of a single LOX gene, whose downregulation impairs both 12- and 15-oxylipins synthesis, together with the in silico 3D protein modelling suggest that PaLOX encodes for a 12/15S-LOX with a dual specificity, and provides additional support to the correlation between cell growth and oxylipin biosynthesis in diatoms.
