    Abstract: The transforming growth factor–β (TGF-β) superfamily comprises nearly 30 growth and differentiation factors that include TGF-βs, activins, inhibins, and bone morphogenetic proteins (BMPs). Multiple members of the TGF-β superfamily serve key roles in stem cell fate commitment. The various members of the family can exhibit disparate roles in regulating the biology of embryonic stem (ES) cells and tumor suppression. For example, TGF-β inhibits proliferation of multipotent hematopoietic progenitors, promotes lineage commitment of neural precursors, and suppresses epithelial tumors. BMPs block neural differentiation of mouse and human ES cells, contribute to self-renewal of mouse ES cells, and also suppress tumorigenesis. ES cells and tumors may be exposed to multiple TGF-β members, and it is likely that the combination of growth factors and cross-talk among the intracellular signaling pathways is what precisely defines stem cell fate commitment. This Connections Map Pathway in the Database of Cell Signaling integrates signaling not only from TGF-β and BMP but also from the ligands nodal and activin, and describes the role of the signaling pathways activated by these ligands in mammalian development. Much of the evidence for the connections shown comes from studies on mouse and human ES cells or mouse knockouts. This pathway is important for understanding not only stem cell biology, but also the molecular effectors of TGF-β and BMP signaling that may contribute to cancer suppression or progression and thus are potential targets for therapeutic intervention.

    Abstract: Sonneratia caseolaris is a widely distributed mangrove plant having much therapeutic importance in traditional medicine. This plant is reported for possessing numerous compounds that are already used for many therapeutic purposes. After finding the presence of antioxidant components in the qualitative antioxidative assay, we went to conduct quantitative tests where the total contents of phenolics, flavonoids, and tannins were estimated as 122 mg GAE/gm, 613 mg QE/gm, and 30 mg GAE/gm, respectively. In DPPH free radical, H2O2, and superoxide radical scavenging assay, the SC50 values were found to be 87, 66, and 192 μg/ml, respectively. In FeCl3 reducing power assay, the RC50 of SC extract and ascorbic acid were 80 and 28 μg/ml, respectively. This extract revealed a significant peripheral analgesic effect in the acetic acid-induced writhing model in mice by reducing the writhing impulse by about 21% and 39% at 250  and 500 mg/kg doses, respectively, and a central analgesic effect in the tail immersion method by elongating the time up to about 22% and 37% at the same doses. In the anti-inflammatory test in mice, this extract reduced the paw edema size over the observed period in a dose-dependent manner. It also showed a significant reduction in the elevated rectal temperature of mice in the observing period in Brewer’s yeast-induced pyrexia model. In silico analysis revealed better binding characteristics of ellagic acid and luteolin among other compounds with various receptors that might be responsible for antioxidative and anti-inflammatory properties. From our observation, we suppose that SC fruits might be a potential source of drug leads for various inflammatory disorders.

    Abstract: Introduction: Copy number variations (CNVs) play a critical role in the pathogenesis of neurodevelopmental disorders (NDD) among children. In this study, we aim to identify clinically relevant CNVs, genes and their phenotypic characteristics in an ethnically underrepresented homogenous population of Bangladesh. Methods: We have conducted chromosomal microarray analysis (CMA) for 212 NDD patients with male to female ratio of 2.2:1.0 to identify rare CNVs. To identify candidate genes within the rare CNVs, gene constraint metrics [i.e., “Critical-Exon Genes (CEGs)”] were applied to the population data. Autism Diagnostic Observation Schedule-Second Edition (ADOS-2) was followed in a subset of 95 NDD patients to assess the severity of autism and all statistical tests were performed using the R package. Results: Of all the samples assayed, 12.26% (26/212) and 57.08% (121/212) patients carried pathogenic and variant of uncertain significance (VOUS) CNVs, respectively. While 2.83% (6/212) patients’ pathogenic CNVs were found to be located in the subtelomeric regions. Further burden test identified females are significant carriers of pathogenic CNVs compared to males (OR = 4.2; p = 0.0007). We have observed an increased number of Loss of heterozygosity (LOH) within cases with 23.85% (26/109) consanguineous parents. Our analyses on imprinting genes show, 36 LOH variants disrupting 69 unique imprinted genes and classified these variants as VOUS. ADOS-2 subset shows severe social communication deficit ( p = 0.014) and overall ASD symptoms severity ( p = 0.026) among the patients carrying duplication CNV compared to the CNV negative group. Candidate gene analysis identified 153 unique CEGs in pathogenic CNVs and 31 in VOUS. Of the unique genes, 18 genes were found to be in smaller ( & lt;1 MB) focal CNVs in our NDD cohort and we identified PSMC3 gene as a strong candidate gene for Autism Spectrum Disorder (ASD). Moreover, we hypothesized that KMT2B gene duplication might be associated with intellectual disability. Conclusion: Our results show the utility of CMA for precise genetic diagnosis and its integration into the diagnosis, therapy and management of NDD patients.

    Abstract: Introduction: Hepatocellular Cancer (HCC) remains the 4th common cause of cancer deaths worldwide. Because it is often diagnosed at an advanced stage in a fragile cirrhotic patient, effective therapies whether they are chemotherapy or biologically based are disappointingly few, with a narrow therapeutic index. Recent studies support a key role for TGF-β signaling in suppressing these tumors. We have previously found that deletion of Smad3/4 adaptor β2SP results in a dramatic and spontaneous formation of liver (HCC) with exon 15 mutations in 11% of human HCC. β2SP+/− and β2SP+/−/Smad3+/− mice develop visceromegaly and multiple cancers (70% of mice), including HCC spontaneously presenting a strong model of the hereditary human cancer syndrome, Beckwith-Wiedemann (BWS) as well as the stages of human HCC. High levels of E3 ligases KEAP1 and PRAJA are observed in human HCCs and in tumors of these mutant mice. Our hypothesis is that disruption of the TGF-β tumor suppressor pathway (through β2SP, Smad3 and Smad4) leads to a proliferative potential in cells that then acquire secondary events such as activation of E3 ligases (KEAP 1, PRAJA and others), presenting these as potentially powerful new targets for HCC. Methods & Results: (1) β2SP+/− and β2SP+/−/Smad3+/− mice are ideal models for a human stem cell disorder (BWS) and HCC progression. (2) Inhibition of PRAJA in the developing Zebrafish embryo leads to high levels of apoptosis. (3) PRAJA is a key E3 Ligase that modulates β2SP and Smad3. (4) PRAJA levels markedly over- expressed in human HCC cell lines and tumor tissues and promotes HCC cell growth. (5) KEAP1 levels are raised in β2SP knockout tissues and human HCCs (6) Knocking-down KEAP1 inhibits HCC tumor cell growth. (7) Seven tumor suppressors are discovered to be potential targets of KEAP1 in HCC. (8) Triterpenoid derivates (Oleanolic Acid/RTA 402/RTA 405) inhibit KEAP1/Nrf2 pathway, as well as PRAJA and inhibit HCC tumor cell growth. Conclusions: Our studies demonstrate that E3 Ligases KEAP1 and PRAJA are dramatically raised in human and mouse hepatocellular cancers when TGF-β signaling is inactivated, inhibiting KEAP1 or PRAJA reduces HCC growth. Determining the synergistic therapeutic effects by targeting both KEAP1 and PRAJA will provide us important insights into development of new therapeutic targets for HCC.

    Abstract: Sonneratia caseolaris (L.) is a common mangrove plant which has significant medicinal value in traditional medicine. Ethanol extract from the fruits of S. caseolaris (SCE) was used in this project to explore its different pharmacological effects considering its traditional usage. In the castor oil-induced diarrheal method, SCE significantly lengthened the latency of the first defecation period up to 95.8 and 119.4 min as well as lowering stool count by 43.3% and 64.4% at the doses of 250 and 500 mg/kg, respectively. In evaluating the neuropharmacological effect using the open-field model, a significant central nervous system (CNS) depressant nature was observed after a reduction in the no. of squares crossed by mice at various time intervals. In evaluating the blood coagulation effect, SCE significantly reduced blood clotting time at 5.86, 5.52, and 5.01 min at 25, 50, and 100 mg/ml doses, respectively. In the assessment of the anthelmintic effect, SCE significantly killed Paramphistomum cervi (P. cervi) where the death times of the nematodes were 40.3, 36.8, and 29.9 min at 12.5, 25, and 50 mg/ml doses, respectively. The extract showed a very poor cytotoxic effect in brine shrimp lethality bioassay. In molecular docking analysis, maslinic acid, oleanolic acid, luteolin, luteolin 7-O-β-glucoside, myricetin, ellagic acid, and R-nyasol showed the best binding affinities with the selected proteins which might be the credible reasons for eliciting pharmacological responses. Among these seven compounds, only luteolin 7-O-β-glucoside had two violations in Lipinski’s rule of five.

    Abstract: Background: Cornonavirus disease (COVID-19) has been declared pandemic by the World Health Organization on the 11th March 2020. The knowledge, attitudes and practices of the population towards the COVID-19, play an integral role in determining community’s readiness to engage themselves in government measures including behavioural change in prevention and control of the disease. Objectives: The study was aimed to determine the knowledge levels, attitudes and practices towards the COVID-19 among the Bangladeshi population. Methods: A cross sectional study was conducted among 1549 adult population across Bangladesh including Dhaka city and rural areas during March-April 2020. Data were collected using a structured and pretested questionnaire through online, self-administered and face to face interview. The study instrument consisted of 7 items on socio-demographic characteristics, 12 items on knowledge, 4 items on attitudes and 5 items on practices related to COVID-19. Independent sample t-tests, chi-square tests, one-way analysis of variance (ANOVA) and binary logistic regression were performed to assess the attitudes and practices in relation to knowledge. Results: Of the total 1549 study population, 1249 were interviewed online, 194 were self-administered and 106 were through face to face interview. The lowest level of knowledge prevailed among the above 50 years’ age group regarding the disease, which was higher among female (p=0.03), and more among the respondents having education level below graduation (p=0.000; OR=1.6, χ2=17.6). Of the total respondents, 73.5% having negative attitude towards use of face mask, though 69.8% having the appropriate knowledge on mode of transmission of the virus (p=0.000). Though, 51.6% of the study population, having adequate knowledge, but only 52.1% using face mask (p 〉 0.05) and 51.8% practicing hand washing (p 〉 0.05). More than 70.0% respondents having knowledge on social distancing, but only 50.0% was practicing it. Male respondents had 1.5 times more knowledge about the social distancing than the female counterpart (p=0.000). Conclusion: Public awareness campaign should be enhanced critically focusing the target audience covering the knowledge gaps, motivation for appropriate practices and further improvement of attitudes towards prevention and control of COVID-19 in Bangladesh thus suggested.

    Abstract: Introduction: Cardiopulmonary bypass increases the incidence of postoperative ventricular arrhythmias in cardiac surgery. Magnesium, which is essential for cardiac function and may prevent arrhythmias, is frequently reduced after cardiac surgery. Aim of the Study: This study aimed to investigate the preventive effects of magnesium infusion in reducing the occurrence of ventricular arrhythmias in individuals who have undergone cardiopulmonary bypass. Methods: This study, done at Bangabandhu Sheikh Mujib Medical University, Dhaka, from July 2020 to June 2022, involved 120 participants in two groups: one received magnesium sulfate following standard cardiopulmonary bypass surgery (Group A), and the other did not (Group B). Both groups were monitored in the ICU with continuous ECG tracking and assessed for ventricular arrhythmias postoperatively on days 0–3. The inclusion criteria comprised adult cardiac patients in preoperative sinus rhythm with normal magnesium levels, excluding those with a history of ventricular arrhythmias or specific medical conditions. Data collected through a questionnaire, interviews, and medical records were analyzed using SPSS version 26. Result: The mean age of the patients in Group A was 53.83±14.54 years and in Group B was 54.50 ± 10.50 years. The mean difference in postoperative Mg++ was statistically significant (p 〈 0.05) in POD 0, POD 1, POD 2, and POD 3. In this study, there were more VA-positive patients in Group B than in Group A; 16.67% had positive ventricular arrhythmia (PVC 8.3%, VT 3.33%, VF 5.00%), while 83.33% were negative VA. Group B had 66.67% negative VA and 33.33% positive VA (PVC 15.00%, VT 10.00%, VF 8.33%). Conclusion: This study identified that the postoperative Mg infusion after cardio pulmonary bypass reduces the incidence of postoperative arrhythmias in cardiac patients. Based on the findings, we recommend using intravenous magnesium as an alternative to prevent ventricular arrhythmias after CPB in cardiac patients.
