Our results suggest that the GNSR constitutes a defence adaptation strategy that is consistently elicited by diverse strains from various phyla, contributes to host protection and involves secondary metabolism.Brassinosteroid (BR) hormones are indispensable for root growth and control both cell division and cell elongation through the establishment of an increasing signalling gradient along the longitudinal root axis. Because of their limited mobility, the importance of BR distribution in achieving a signalling maximum is largely overlooked. Expression pattern analysis of all known BR biosynthetic enzymes revealed that not all cells in the Arabidopsis thaliana root possess full biosynthetic machinery, and that completion of biosynthesis relies on cell-to-cell movement of hormone precursors. We demonstrate that BR biosynthesis is largely restricted to the root elongation zone, where it overlaps with BR signalling maxima. Moreover, optimal root growth requires hormone concentrations to be low in the meristem and high in the root elongation zone, attributable to increased biosynthesis. Our finding that spatiotemporal regulation of hormone synthesis results in local hormone accumulation provides a paradigm for hormone-driven organ growth in the absence of long-distance hormone transport in plants.The Ubiquitin-Specific Protease 22 (USP22) is a deubiquitinating subunit of the mammalian SAGA transcriptional co-activating complex. USP22 was identified as a member of the so-called "death-from-cancer" signature predicting therapy failure in cancer patients. However, the importance and functional role of USP22 in different types and subtypes of cancer remain largely unknown. In the present study, we leveraged human cell lines and genetic mouse models to investigate the role of USP22 in HER2-driven breast cancer (HER2+-BC) and demonstrate for the first time that USP22 is required for the tumorigenic properties in murine and human HER2+-BC models. learn more To get insight into the underlying mechanisms, we performed transcriptome-wide gene expression analyses and identified the Unfolded Protein Response (UPR) as a pathway deregulated upon USP22 loss. The UPR is normally induced upon extrinsic or intrinsic stresses that can promote cell survival and recovery if shortly activated or programmed cell death if activated for an extended period. Strikingly, we found that USP22 actively suppresses UPR induction in HER2+-BC cells by stabilizing the major endoplasmic reticulum (ER) chaperone HSPA5. link2 Consistently, loss of USP22 renders tumor cells more sensitive to apoptosis and significantly increases the efficiency of therapies targeting the ER folding capacity. link3 Together, our data suggest that therapeutic strategies targeting USP22 activity may sensitize tumor cells to UPR induction and could provide a novel, effective approach to treat HER2+-BC.

We aimed to evaluate oncological and functional outcomes of index lesion HIFU ablation with Focal-One

.

We prospectively assessed treatment-naïve men with localized prostate cancer between 2017 and 2019. Inclusion criteria were stage cT ≤ 2, ≥5 years of life expectancy, grade group ≤3. Multiparametric magnetic resonance was performed before ablation. Patients with a prostate volume of ≥80 ml underwent debulking. Treatment failure was defined as a histologically confirmed tumor that required salvage treatment or androgen deprivation therapy.

One hundred and eighty nine patients were enrolled. Data are presented as median and Interquartile Range (IQR). Median age was 70(11) years. Median baseline PSA was 5.8(3) ng/ml. Fourteen (7.4%) patients had prostate debulking before ablation. 104 (55%) patients underwent targeted ablation, 45 (23.8%) extended targeted ablation, 31 (16.4%) hemiablation, and 9 (4.8%) extended hemiablation. Median targeted ablated volume was 14(9) ml. Ninety-three complications occurrmodels (one for IPSS and one for IEEF-15) were estimated and they showed that time reaches the statistical significance coefficient only for the IEEF-15, meaning that subsequent evaluations of the indicators were significantly lower at each time point.

Index lesion HIFU ablation demonstrated satisfactory early oncological outcome but anteriorly located tumors had inadequate ablation. Urinary function was well preserved. Sexual function slightly decreased during follow-up.

Exercise is increasingly recognized as an effective strategy to improve cancer prevention and prognosis. Several biological mechanisms mediating these benefits have been proposed, but the role of epigenetics remains largely unknown. Since epigenetics is highly susceptible to lifestyle factors, we hypothesized that exercise could affect the epigenome landscape in cancer tissues.

Rats implanted with AT1 prostate tumors were randomized to either control or exercise training. microRNA expression, DNA methylation and histone acetylation were analyzed in the tumor tissue.

MiR-27a-5p appeared to be differently expressed between sedentary and trained rats. Furthermore, exercise increased global DNA methylation and decreased DNA methyltransferases mRNA expression in the tumor tissue. Histone acetylation however remained unaltered.

Overall, exercise might reverse some of the cancer-related epigenetic alterations in the prostate tumor tissue.

To explore the potential mechanisms of SARS-CoV-2 in targeting the prostate gland, leading to exacerbation of benign prostatic hyperplasia (BPH) symptoms and greater risks of BPH complications such as acute urinary retention.

A categorized and comprehensive search in the literature has been conducted by 10 April 2021 using international databases including PubMed, Embase, Web of Science, Scopus, and Cochrane Library in line with the PRISMA guidelines recommendations. PICO strategy was used to formulate the research question. The following terms were used urology, COVID-19, coronavirus, BPH, inflammation, androgen receptors, LUTS, IPSS, PSA, and SARS-CoV-2 or a combination of them. Studies with irrelevant purposes and duplicates were excluded. The selected studies were performed on humans and published in English.

The research revealed 89 articles. After title screening and considering exclusion criteria, 52 papers were included for the systematic review. BPH is a common condition affecting older men. SA questionnaires (e.g., IPSS) and serum biomarkers (e.g., PSA).

Based on the current findings, SARS-CoV-2 can possibly damage the prostate and worsen BPH and its related LUTS through ACE2 signaling, AR-related mechanisms, inflammation, and metabolic derangement. We encourage future studies to investigate the possible role of COVID-19 in the progression of BPH-related LUTS and examine the prostatic status in susceptible patients with relevant available questionnaires (e.g., IPSS) and serum biomarkers (e.g., PSA).

Most men who die of prostate cancer are older than 70 years. The ChemoHormonal Therapy Versus Androgen Ablation Randomized Trial for Extensive Disease in Prostate Cancer (CHAARTED) randomized men of all ages with metastatic hormone-sensitive prostate cancer (mHSPC) to receive androgen deprivation therapy (ADT) with or without docetaxel demonstrating an overall survival (OS) benefit for docetaxel.

In a post-hoc analysis of this trial, we assessed patient characteristics and OS in patients ≥70 years ("older men") versus <70 years ("younger men") with Cox proportional hazards models. In addition, we compared adverse events, therapy completion rate, and subsequent treatment patterns between these two groups using Chi-squared tests.

177 (22.4%) patients were ≥70 years. Docetaxel + ADT resulted in improved OS in both older and younger men (Hazard Ratio [HR] 0.45, 95%CI 0.25-0.80 for older men; HR 0.71, 95%CI 0.53-0.95 for younger men). This treatment benefit was seen for subgroups of older men with high vowhen receiving docetaxel + ADT. Oncologists should consider docetaxel chemotherapy as a favorable treatment option for older men with mHSPC who are fit for chemotherapy.

Physical activity (PA) is associated with favorable outcomes in prostate cancer (PCa) patients. We assessed its effect on the risk of PCa reclassification (PCaR) during active surveillance.

Anthropometric, demographic, and clinical data concerning men diagnosed with a low-risk PCa and initially managed with active surveillance at the two participating institutions were retrospectively collected. The Physical Activity Scale for the Elderly (PASE) was used for patients' self-assessment of their daily exercise and their consequent stratification into three groups sedentary (PASE ≤ 65), moderately active (65 < PASE < 125), active (PASE ≥ 125). Kaplan-Meier model was used to evaluate the predictive role of PA on PCaR, computed at 2, 5, 10 years after diagnosis; differences between lifestyle groups were assessed using the log-rank and uni-/multivariable Cox analyses applied to identify predictors of reclassification.

Eighty-five patients were included in the analysis, with a median age of 66 years (IQR ergoing active surveillance.

PA influences PCa evolution, as increasing levels are associated with a significantly reduced risk of tumor reclassification among patients undergoing active surveillance.

Obesity is common among people living with HIV (PLWH) and early-stage infection, yet associations with combination antiretroviral (cART) adherence are unclear.

Among PLWH initiating cART in Uganda and South Africa, body mass index (BMI) was assessed at cART initiation, and cART adherence was monitored in real-time over 12 months. The association of obesity (BMI ≥ 30 kg/m

) with adherence was assessed among nonpregnant participants with CD4 > 350 cells/mm

using fractional regression modeling.

Among 322 participants, median age was 32 years, 70% were female, and 54% were from Uganda. Prevalence of obesity was 12% in Uganda and 28% in South Africa. Mean overall cART adherence was 83% in Uganda and 66% in South Africa. Participants with obesity had higher adherence than those without obesity +3.6% (p = 0.44) in Uganda and +11.4% (p = 0.02) in South Africa.

Obesity at cART initiation was common and associated with higher adherence, although only significantly in South Africa.

There is growing interest in individuals with NWO, which is an underdiagnosed and understudied group, because of their increased risk for cardiometabolic morbidity and mortality. In this review, we summarized the definition, prevalence, etiology, pathophysiology, and cardiovascular outcomes seen in NWO. We have also summarized the available literature on interventions for NWO. There is a wide variation in the body fat percent cutoffs used to diagnose excess body fat. Hence, the prevalence rates of NWO vary between different populations and studies. It is estimated that about 30 million Americans have NWO and the worldwide prevalence ranges from 4.5% to 22%. Genetics, diet, and physical activity are related to NWO. However, etiological factors are not clear. Changes in body composition, inflammation, oxidative stress are present in NWO in comparison to normal weight lean (NWL) who have a normal BMI and normal body fat amount.
