Empowerment through Traditional Knowledge System for Agricultural sustainability

158-161Developing agricultural sustainability by harnessing Indigenous Knowledge often referred to as Traditional Knowledge. Innovations and practices derived out of success stories from rural locale provided zeal to research scholars to probe into these systems of empowerment. Educational initiatives ranging from classroom culture to farmer centered knowledge require a thorough research investigation and ultimately need to be introduced in higher education. Rich cultural heritage and knowledge dimensions, which have natural tendency to diminish with spatio-temporal changes need to be protected and is required to be brought back either in its native form or slightly modified form. Either of these may be, advantageous for agricultural productivity. Indigenous knowledge, which is centered on beliefs, practices and traditional technologies, is required to be documented through systematic planned approach by educational initiatives. As a prelude to educational initiatives, documenting Indigenous Knowledge, through established protocols may be the primary requirement. This includes community, individual and public domain knowledge systems, so that the existing data structures and efforts of organizations working to document this knowledge system are strengthened

Outcomes of Patients with Budd-Chiari Syndrome and Factors Predicting the Need for TIPS & Liver Transplantation - a Single-Center Long-Term Experience

Abstract Background: Budd-Chiari Syndrome (BCS) is a complex thrombotic disorder caused due to obstruction of hepatic venous outflow involving anywhere from small hepatic venules to the entrance of inferior vena cava into the right atrium. This leads to venous stasis and ischemic injury of hepatic parenchyma and sinusoids, with the risk of liver failure. The prognosis of patients with BCS had improved significantly with long-term anticoagulation and measures like Trans-Jugular-Intrahepatic-Porto-Systemic shunt (TIPS) and liver transplantation. We report the outcomes of patients who follow in our hematology practice and describe the factors predicting the need for TIPS/Liver Transplant. Methods: After appropriate Investigational Review Board permission, we identified patients with a history of BCS following in our thrombosis clinical practice from the year 2010 onwards. We evaluated their laboratory, demographic, anticoagulation data, Model of End-stage Liver Disease (MELD) score, Child-Pugh (CP) score at diagnosis or when earliest available, and other relevant clinical information as outlined. Descriptive statistics with medians, quartiles, frequencies, and percentages are reported. Further, we compared the two categories of patients who needed TIPS/Liver transplants versus those who did not. SAS version 9.4 was used for analysis. For continuous variables, a univariate nonparametric Mann-Whitney test was used. The Fisher's Exact Test was used to associate each variable with the need for TIPS/Liver Transplant. Results: Our study included 23 patients with baseline characteristics, including median age of 36 years (11-59 years), 91% whites, 61% females, 44% smokers, 61% obese(median BMI 29.9 kg/m 2), 6 of 14 women on oral contraceptive pills, 22% with thrombosis history, 17% with stroke history, median hemoglobin 13.4 gm/dL(8.9-20 gm/dL), white blood cell count 9,400/L (3,050-31,500/L), platelet count 294,000/L(14,000-767,000/L), serum creatinine 0.87 mg/L (0.55-2.52 mg/dL), total protein 6.3 gm/dL (5.2-8.8 gm/dL), Bilirubin 2.1 mg/dL(0.1-20.2 mg/dL), Aspartate Aminotransferase (AST) 61 U/L(16-1037 U/L), Alanine Aminotransferase (ALT) 43U/L(18-1694 U/L), MELD score 15 (range 7-38), CP score 9 (5-14), 74% with cirrhosis, 82% with ascites at one point, 57% with myeloproliferative neoplasm (MPN), 4.3% with Paroxysmal Nocturnal Hemoglobinuria (PNH), 17% with Antiphospholipid antibodies positive (APS), 13% had positive antinuclear antibodies, 35% needed TIPS and 44% required liver transplantation. 57% with Janus Kinase (JAK2) V617F mutation (1 patient with a low variant allele frequency of 1%), 1 patient (4.3%) had Calreticulin (CALR) mutation positive MPN, 91% remained on long-term anticoagulation with 40% using warfarin, 35% apixaban, 9% Enoxaparin or Rivaroxaban for long-term anticoagulation, 13% developed heparin-induced thrombocytopenia (HIT). 8.7% had developed BCS after Ad26.COV2.S vaccine to prevent SARS-CoV-2 infection. Excluding the patients with missing variables, 5 of 12 had Protein C deficiency, 3 or 10 had Protein S deficiency, 8 of 20 with Antithrombin (AT) deficiency, 4 of 14 with heterozygous factor V Leiden mutation, 0 of 10 with prothrombin gene mutation, 1 of 13 with hyper-homocysteinemia. 35% had gastrointestinal bleeding though 65% of patients had evidence of varices by endoscopy. When the group needing TIPS/Liver transplant/died is compared to those who did not, they had higher bilirubin, MELD, PC score, AT deficiency, cirrhosis, ascites, and JAK2 mutation (p-value significant: Table 1). With a median follow-up of 90 months, overall survival was not statistically significant between the two groups (Figure 1). Two patients (8.7%) died out of a total of 23. Conclusions: Our data indicate that in patients with BCS, neoplasms (61%), particularly MPN (57%), are very commonly diagnosed. Compared to the historical data in patients with BCS with dismal prognosis (60-80% six-month mortality rate), the overall survival had significantly improved, likely due to supportive measures like TIPS/Liver transplant and long-term anticoagulation. Outside the established variables like CP and MELD, lower antithrombin activity and positive JAK2 mutation status also predicted a higher TIPS/Liver transplant need. Figure 1 Figure 1.

Associations of Budd-Chiari Syndrome and Factors Predicting Need for TIPS and Liver Transplantation: Long-Term Single-Center Experience

Background: Budd-Chiari Syndrome (BCS) is a rare thrombotic disorder that involves obstruction of hepatic venous outflow. It can result in increased sinusoidal pressure and portal hypertension. Patients may develop cirrhosis and liver failure from chronic injury, along with other complications such as ascites and varices. BCS is associated with thrombophilia and hematological disorders such as myeloproliferative neoplasms (MPNs) and other auto-immune diseases. Patients typically receive long-term anticoagulation to decrease the risk of recurrence of thrombosis along with supportive measures such as trans-jugular intrahepatic portosystemic shunt (TIPS) and liver transplant. Methods: We performed a retrospective study to describe the patient population with BCS at UNMC. We evaluated 23 patient medical records and collected data on demographics, risk factors, health history, BCS presentation, associated diseases, any acquired/inherited thrombophilia, laboratory results at the earliest available date from diagnosis, and treatments/procedures received. Model of End-Stage Liver Disease (MELD) and Child-Pugh scores were calculated and reported. Descriptive Findings: The median age for the 23 patients in our study was 36 years (range: 11-59 years). The percentage of females was 60.87%. The overall survival rate was 91.3%. Median follow-up duration was 89 months (range: 3-330 months). Of the total, 57% of the patients had myeloproliferative neoplasms (MPNs). Cirrhosis of liver was observed in 74% of the patients. 8.7% of patients developed BCS after receiving the COVID-19 vaccine (Ad26.COV2.S). 91.3% of patients received long-term anticoagulation. 65% of patients received TIPS and/or liver transplant. Conclusion: The most common primary cause of BCS in our study was MPNs (57%). Vaccine-induced thrombotic thrombocytopenia (VITT) after COVID-19 vaccine was found to be a newly described primary cause of BCS.https://digitalcommons.unmc.edu/surp2021/1046/thumbnail.jp

Significance of LIF/LIFR Signaling in the Progression of Obesity-Driven Triple-Negative Breast Cancer

American women with obesity have an increased incidence of triple-negative breast cancer (TNBC). The impact of obesity conditions on the tumor microenvironment is suspected to accelerate TNBC progression; however, the specific mechanism(s) remains elusive. This study explores the hypothesis that obesity upregulates leukemia inhibitory factor receptor (LIFR) oncogenic signaling in TNBC and assesses the efficacy of LIFR inhibition with EC359 in blocking TNBC progression. TNBC cell lines were co-cultured with human primary adipocytes, or adipocyte-conditioned medium, and treated with EC359. The effects of adiposity were measured using cell viability, colony formation, and invasion assays. Mechanistic studies utilized RNA-Seq, Western blotting, RT-qPCR, and reporter gene assays. The therapeutic potential of EC359 was tested using xenograft and patient-derived organoid (PDO) models. The results showed that adipose conditions increased TNBC cell proliferation and invasion, and these effects correlated with enhanced LIFR signaling. Accordingly, EC359 treatment reduced cell viability, colony formation, and invasion under adipose conditions and blocked adipose-mediated organoid growth and TNBC xenograft tumor growth. RNA-Seq analysis identified critical pathways modulated by LIF/LIFR signaling in diet-induced obesity mouse models. These findings suggest that adiposity contributes to TNBC progression via the activation of the LIF/LIFR pathway, and LIFR inhibition with EC359 represents a promising therapeutic approach for obesity-associated TNBC

PELP1 inhibition by SMIP34 reduces endometrial cancer progression via attenuation of ribosomal biogenesis

Endometrial carcinoma (ECa) is the fourth most common cancer among women. The oncogene PELP1 is frequently overexpressed in a variety of cancers, including ECa. We recently generated SMIP34, a small‐molecule inhibitor of PELP1 that suppresses PELP1 oncogenic signaling. In this study, we assessed the effectiveness of SMIP34 in treating ECa. Treatment of established and primary patient‐derived ECa cells with SMIP34 resulted in a significant reduction of cell viability, colony formation ability, and induction of apoptosis. RNA‐seq analyses showed that SMIP34‐regulated genes were negatively correlated with ribosome biogenesis and eukaryotic translation pathways. Mechanistic studies showed that the Rix complex, which is essential for ribosomal biogenesis, is disrupted upon SMIP34 binding to PELP1. Biochemical assays confirmed that SMIP34 reduced ribosomal biogenesis and new protein synthesis. Further, SMIP34 enhanced the efficacy of mTOR inhibitors in reducing viability of ECa cells. SMIP34 is also effective in reducing cell viability in ECa organoids in vitro and explants ex vivo. Importantly, SMIP34 treatment resulted in a significant reduction of the growth of ECa xenografts. Collectively, these findings underscore the potential of SMIP34 in treating ECa

The LIFR Inhibitor EC359 Effectively Targets Type II Endometrial Cancer by Blocking LIF/LIFR Oncogenic Signaling

Endometrial cancer (ECa) is the most common female gynecologic cancer. When comparing the two histological subtypes of endometrial cancer, Type II tumors are biologically more aggressive and have a worse prognosis than Type I tumors. Current treatments for Type II tumors are ineffective, and new targeted therapies are urgently needed. LIFR and its ligand, LIF, have been shown to play a critical role in the progression of multiple solid cancers and therapy resistance. The role of LIF/LIFR in the progression of Type II ECa, on the other hand, is unknown. We investigated the role of LIF/LIFR signaling in Type II ECa and tested the efficacy of EC359, a novel small-molecule LIFR inhibitor, against Type II ECa. The analysis of tumor databases has uncovered a correlation between diminished survival rates and increased expression of leukemia inhibitory factor (LIF), suggesting a potential connection between altered LIF expression and unfavorable overall survival in Type II ECa. The results obtained from cell viability and colony formation assays demonstrated a significant decrease in the growth of Type II ECa LIFR knockdown cells in comparison to vector control cells. Furthermore, in both primary and established Type II ECa cells, pharmacological inhibition of the LIF/LIFR axis with EC359 markedly decreased cell viability, long-term cell survival, and invasion, and promoted apoptosis. Additionally, EC359 treatment reduced the activation of pathways driven by LIF/LIFR, such as AKT, mTOR, and STAT3. Tumor progression was markedly inhibited by EC359 treatment in two different patient-derived xenograft models in vivo and patient-derived organoids ex vivo. Collectively, these results suggest LIFR inhibitor EC359 as a possible new small-molecule therapeutics for the management of Type II ECa
