Ring finger protein 138 inhibits transcription factor C/EBPα protein turnover leading to differentiation arrest in acute myeloid leukemia.

E3 ubiquitin ligase, ring finger protein 138 (RNF138) is involved in several biological processes; however, its role in myeloid differentiation or tumorigenesis remains unclear. RNAseq data from TNMplot showed that RNF138 mRNA levels are highly elevated in acute myeloid leukemia (AML) bone marrow samples as compared with bone marrow of normal volunteers. Here, we show that RNF138 serves as an E3 ligase for the tumor suppressor CCAAT/enhancer binding protein (C/EBPα) and promotes its degradation leading to myeloid differentiation arrest in AML. Wild-type RNF138 physically interacts with C/EBPα and promotes its ubiquitin-dependent proteasome degradation while a mutant RNF-138 deficient in ligase activity though interacts with C/EBPα, fails to down-regulate it. We show that RNF138 depletion enhances endogenous C/EBPα levels in peripheral blood mononuclear cells (PBMCs) isolated from healthy volunteers. Our data further shows that RNF138-mediated degradation of C/EBPα negatively affects its transactivation potential on its target genes. Furthermore, RNF138 overexpression inhibits all-trans-retinoic acid-induced differentiation of HL-60 cells whereas RNF138 RNAi enhances. In line with RNF138 inhibiting C/EBPα protein turnover, we also observed that RNF138 overexpression inhibited ß-estradiol (E2)-induced C/EBPα driven granulocytic differentiation in C/EBPα inducible K562-p42C/EBPα-estrogen receptor cells. Furthermore, we also recapitulated these findings in PBMCs isolated from AML patients where depletion of RNF138 increased the expression of myeloid differentiation marker CD11b. These results suggest that RNF138 inhibits myeloid differentiation by targeting C/EBPα for proteasomal degradation and may provide a plausible mechanism for loss of C/EBPα expression often observed in myeloid leukemia. Also, targeting RNF138 may resolve differentiation arrest by restoring C/EBPα expression in AML.

Cancer stem cell biomarkers SOX2 and Oct4 in cervical cancer patients undergoing chemoradiotherapy.

BACKGROUND: Cancer stem cell biomarkers SRY (sex-determining region Y)-box 2 (SOX2) and octamer-binding transcription factor 4 (Oct4) account for radioresistance in cervical squamous cell cancers (CSCCs). Their clinical implications are limited and contradictory. METHODS: In this prospective cohort study, we recruited patients with FIGO IB2-IVA CSCC treated with primary chemoradiotherapy on regular follow-up. Tissue biopsy specimens were evaluated for SOX2 and Oct4 expression by immunohistochemistry, quantified by a product of proportion and intensity scores. RESULTS: A total of 59 patients were included. Most had a moderately differentiated (81%), keratinizing (59%) CSCC, and ≥FIGO stage IIB disease (95%). SOX2 expression (high:low 21:38 patients) and Oct4 expression (high:low 4:55 patients) had a significant interrelation (p = 0.005, odds ratio (95% CI) - 1.23 (1.004-1.520)). At a median follow-up of 36 months, the 3-year overall survival (OS) was 60% and 53% for low and high SOX2 expression (p = 0.856), and 54% and 100% for low and high Oct4 expression (p = 0.114). The 3-year disease-frese survival (DFS) was 65% and 50% in the low and high SOX2 expression (p = 0.259), and 59% and 75% for low and high Oct4 expression (p = 0.598). SOX2 expression was the only variable significantly associated with a lower OS and DFS on regression analysis. CONCLUSION: Our study demonstrated a trend toward improved OS and DFS with low SOX2 and high Oct4 expression in CSCC patients undergoing chemoradiotherapy.

A new class of teraryl-based AIEgen for highly selective imaging of intracellular lipid droplets and its detection in advanced-stage human cervical cancer tissues.

Lipid droplets (LDs) have drawn much attention in recent years. They serve as the energy reservoir of cells and also play an important role in numerous physiological processes. Furthermore, LDs are found to be associated with several pathological conditions, including cancer and diabetes mellitus. Herein, we report a new class of teraryl-based donor-acceptor-appended aggregation-induced emission luminogen (AIEgen), 6a, for selective staining of intracellular LDs in in vitro live 3T3-L1 preadipocytes and the HeLa cancer cell line. In addition, AIEgen 6a was found to be capable of staining and quantifying the LD accumulation in the tissue sections of advanced-stage human cervical cancer patients. Unlike commercial LD staining dyes Nile Red, BODIPY and LipidTOX, AIEgen 6a showed a high Stokes shift (195 nm), a good fluorescence lifetime decay of 12.7 ns, and LD staining persisting for nearly two weeks.

External Beam Radiotherapy Interdigitated with High Dose Rate(HDR) Intracavitary Brachytherapy versus External Beam Radiotherapy followed by Sequential HDR Intracavitary Brachytherapy for Locally Advanced Carcinoma Cervix-Randomized Control Study.

BACKGROUND: In cervical cancer treatment, overall treatment time (OTT) is an important prognostic factor. This study compares the clinical outcomes when High-Dose-Rate Intracavitary-Brachytherapy(HDR-ICRT) is interdigitated with external beam radiotherapy(EBRT) versus sequential HDR-ICRT after EBRT in the treatment of locally advanced carcinoma cervix. METHODS: Histologically confirmed carcinoma cervix patients [FIGO Stage IIB-IVA (except IIIC-2)] were included and randomized into two groups. The study group received EBRT 50Gy in 25 fractions with interdigitated HDR-ICRT 7Gy per fraction weekly for three fractions starting after completion of 3 weeks of EBRT or as soon as cervical os became negotiable thereafter. Patients in the control group received EBRT 50Gy in 25 fractions with sequential HDR-ICRT 7Gy per fraction weekly for three fractions starting one week after completion of EBRT. All patients were regularly followed up during and after radiotherapy for local toxicity and disease control. RESULTS: This study enrolled 102 patients; 51 in each arm. Median OTT in study and control arm were 46 and 60 days, respectively. Median follow-up duration was 24 months (two years). Loco-regional control after two years of follow-up was 84.31 % and 72.54% of patients in study arm control arm respectively (p-value 0.148). Two (3.92%) patients from study arm and eight (15.68%) from control arm had residual disease. Two patients in study arm and one from control arm had local recurrence. Two patients from study arm three patients from control arm developed distant metastases. RTOG mucosal grade III acute mucosal toxicity in either arm. Cervical-os negotiability was limiting factor for interdigitated HDR-ICRT. CONCLUSIONS: Interdigitated HDR-ICRT with EBRT may give local control with manageable toxicities as compared to sequential HDR-ICRT, with the advantage of significant reduction in OTT.

Palliative radiotherapy: a one-week course in advanced head and neck cancer - quality of life outcomes.

OBJECTIVES: Palliative radiotherapy regimens for advanced head and neck cancers vary in doses and treatment times. Their quality of life (QoL) implications are not clearly established. METHODS: We randomised patients with advanced, non-metastatic, head and neck squamous cell carcinomas (stage IVA-B) with WHO performance score of 2 or higher to receive 30 Gy in 10 fractions over two weeks (arm A) or 20 Gy in 5 fractions over one week (arm B). QoL was assessed using European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaires (QLQ)-C30 and QLQ-H&N35 questionnaires at baseline and postradiotherapy. The primary endpoint was the EORTC-defined global health status. Secondary endpoints were functional and symptom scores of QoL, response to radiotherapy and acute toxicities. The primary aim was to evaluate the one-week regimen in terms of QoL to the longer regimen. RESULTS: 110 patients were randomised, the number of patients in the final analysis was 95: 49 in arm A and 46 in arm B. Baseline characteristics were similar. Clinical outcomes post-treatment were comparable. Postradiotherapy, there were improved scores for functional and symptom scales, the differences were non-significant. The duration of treatment was significantly reduced in arm B (p<0.01) with a lower score for financial difficulty (p<0.001). The difference in global health status (primary endpoint) was non-significant (p=0.82). The median overall survival was 7 months, the median progression-free survival was 5 months and these did not vary between the two groups. CONCLUSION: One-week palliative radiotherapy for head and neck cancers achieves similar QoL and clinical outcomes as more protracted radiotherapy schedules with significantly reduced treatment time and financial toxicity.

Evaluation of correlation between CD44, radiotherapy response, and survival rate in patients with advanced stage of head and neck squamous cell carcinoma (HNSCC).

PURPOSE: Cancer stem cells (CSCs) constitute a distinctive subpopulation of cancer cells that are competent in tumor initiation, invasion, recurrence, and resistance to chemoradiotherapy. CD44, a hyaluronic acid (HA) receptor has been considered as a potential CSC marker in head and neck cancer. The purpose of this study is to evaluate the correlation between CD44 and clinicopathological parameters, treatment response, survival, and recurrence. METHODS: The CD44 expression was examined by immunohistochemistry (IHC) in 90 samples of head and neck squamous cell carcinoma (HNSCC) confirmed patients. The expression of CD44 and its association with clinicopathological parameters, treatment response, and survival was determined. RESULTS: In all HNSCC patient samples, CD44 was expressed consistently at different intensities. Tumor size (p < 0.001), stage (p < 0.001), and treatment response (p < 0.001) showed statistically significant association with CD44 expression. Alcohol and CD44 were observed as independent predictors of response to radiotherapy using multivariate ordinal logistic regression analysis. Analysis of 2-year overall survival (OS) showed that CD44 expression (p = 0.02), tumor size (p = 0.001), lymph node status (p < 0.001), stage (p < 0.001), and grade (p = 0.007) were significantly associated with OS. Using Cox regression analysis, lymph node status (p = 0.001), grade (p < 0.001), recurrence (p < 0.001), and CD44 expression (p = 0.003) were found to be potential independent predictors of OS. CONCLUSION: Our findings suggest that CD44 contributes to resistance to radiotherapy and poor OS. The results also suggest that except for CD44 there could be other factors such as lymph node metastasis, grade, and alcohol which should be investigated as potential targets for therapy.

Clinical Significance of Circulating Serum Levels of sCD95 and TNF-α in Cytoprotection of Cervical Cancer.

Background: This study correlates the serum levels of sCD95 & TNF-α with a simple cell-based assay to evaluate the capacity of the serum sample to induce apoptosis in Jurkat cells. Interlinking of these parameters can be explored to design a minimum invasive diagnostic strategy for cervical cancer (CC). Methods: Sera samples were assessed to induce apoptosis in Jurkat cells through FACS. Serum levels of sCD95 and TNF-α were measured by ELISA. JNK phosphorylation was evaluated in sera incubated Jurkat cells. Data was scrutinized through statistical analysis. Results: Significantly higher serum levels of sCD95 and lower TNF-α levels were observed in CC patients; their sera samples inhibited induction of apoptosis in Jurkat cells through reduced JNK phosphorylation. Statistical analysis linked these three parameters for the early screening of CC. Conclusion: Distinct sera levels of sCD95 & TNF-α in CC patients showed an anti-apoptotic effect, which can be considered for early detection of CC.

Treatment outcomes in poor metabolizers of cytochrome P450 2A6 with concurrent chemoradiotherapy in locally advanced head- and neck-squamous cell carcinoma.

Introduction: Human Cytochrome 2A6 (CYP2A6) is involved in the oxidative metabolism of the nicotine to the inactive cotinine. CYP2A6 is a primary enzyme in nicotine metabolism, the enzyme has been proposed as a novel target for smoking cessation. Materials and Methods: A total of 70 male patients of locally advanced head- and neck-squamous cell carcinoma confirmed by histopathological examination were enrolled in this study. All patients received concurrent chemoradiotherapy (total dose of 70 Gray in 35 fractions in 7 weeks with concurrent tablet capecitabine 1250 mg/m2/day). Response assessment was based on response evaluation criteria in solid tumor criteria. Total ribonucleic acid (RNA) was isolated from the whole blood of all patients by TRI REAGENT BD (SIGMA USA) followed by real-time polymerase chain reaction assay which was done in studying messenger RNA (mRNA) expression of Excision Repair Cross Complementation Group 1 in blood lymphocytes of patient. Results: The most common stage prevalent was Stage IV A in 28 (56%) patients followed by Stage III in 16 (32%) patients. Out of 70, 20 (28.6%) patients defaulted for treatment, so the analysis was done in 56 patients. A total of 19 (34%) patients had a complete response (CR) and 17 (30%) patients had no response. In all the patients who had CR, posttreatment relative quantification (RQ) expression levels were high. Among nonresponders only three had higher RQ folds and the rest 14 had lower RQ folds. Conclusion: Posttreatment expression levels of CYP2A6 were found to be a better predictor for tumor response to the treatment than the pretreatment expression levels. Almost all the patients having higher RQ folds had CR and those having lower RQ folds had either no response or progressive disease on follow-up visits.

Modulation of protein phosphatase 1 gamma 2 during cell division of cervical cancer HeLa cells.

INTRODUCTION: Protein phosphatases (PP) and kinases are known to regulate the cell cycle dynamics. Although kinases have been studied extensively, most of the phosphatases are still unexplored. Therefore, the present study aimed to investigate the association of an isoform of PP1 family protein phosphatases 1 gamma 2 (PP1γ2) in the regulation of cervical cancer HeLa cell proliferation. MATERIAL AND METHODS: Expression of PP1γ2 transcript and protein was assessed in the cervical cancer cell line of HeLa cells through RT-PCR and western blotting. Flow cytometry was employed to confirm its expression quantitatively, and Immuno-fluorescence was done to evaluate the distribution of PP1γ2 in the dividing mononuclear and Taxol-induced multipolar HeLa cells. PP1γ2-specific siRNA-mediated silencing was done to understand downstream pathways. The effect of the hypoxic tumour microenvironment on PP1γ2 expression was also evaluated. RESULTS: RT-PCR and western blotting confirmed the expression of PP1γ2 in HeLa cells, and flow cytometry analysis established intracellular expression of PP1γ2. Immunofluorescence is localized PP1γ2 in the nucleus of mononuclear cells during interphase, whereas it is transiently redistributed to spindle poles throughout the cell division and localized back to the nucleus after complete karyokinesis. Taxol-induced multipolar HeLa cells also showed a temporal redistribution of PP1γ2 on the spindle poles. Hypoxic conditions upregulated PP1γ2 expression, but downregulated PP1γ2 levels through siRNA increased GSK3ß phosphorylation. CONCLUSIONS: Collectively, data suggests that PP1γ2 is modulated during HeLa cell division and regulates GSK3ß phosphorylation, which may regulate downstream signalling of cell division.

Polymorphism in cytochrome P4502A6 reduces the risk to head and neck cancer and modifies the treatment outcome.

The present case-control study consisting of 1300 cases of head and neck squamous cell carcinoma (HNSCC) and the equal number of controls aimed to investigate the association of functionally important polymorphisms in cytochrome P4502A6 (CYP2A6*1B, CYP2A6*4C, CYP2A6*9-rs28399433) with HNSCC and the treatment response in cases receiving a combination of chemotherapy/radiotherapy (CT/RT). A significant decrease in risk to HNSCC was observed in the cases with deletion (CYP2A6*4B and CYP2A6*4C) or reduced activity genotypes (CYP2A6*9) of CYP2A6. This risk to HNSCC was further reduced significantly in tobacco users among the cases when compared to nontobacco users among the cases. The risk was also reduced to a slightly greater extent in alcohol users among the cases when compared to nonalcohol users among the cases. In contrast with decreased risk to HNSCC, almost half of the cases with variant genotypes of CYP2A6 (CYP2A6*1A/*4C+*1B/*4C+*4C/*4C and *9/*9) did not respond to the treatment. Likewise, the survival rate in cases receiving the treatment, after 55 months of follow-up was significantly lower in cases with deletion (6.3%) or reduced activity (11.9%) allele than in the cases with common alleles (41%). The present study has shown that CYP2A6 polymorphism significantly reduces the risk to HNSCC. Our data further suggested that CYP2A6 polymorphism may worsen the treatment outcome in the cases receiving CT/RT.

Frequent expression of a novel cancer testis antigen, protein kinase human monopolar spindle 1 (hMps1/TTK) in human urinary bladder transitional cell carcinoma.

Urothelial bladder cancer (UBC) is a frequently occurring malignancy of the urinary tract. The present study was undertaken to evaluate the mRNA and immunohistochemical (IHC) expression of protein kinase human monopolar spindle 1 (hMps1/TTK) gene in transitional cell carcinoma (TCC) of the bladder and correlate its expression with the clinicopathological characteristics of patients. In the present study, quantitative real-time reverse-transcriptase polymerase chain reaction (qRT-PCR) was used to evaluate TTK mRNA expression in TCC. IHC analysis of TTK was also evaluated. Independent Student's t, ANOVA and chi-square (χ2) tests were used to analyze the data statistically. The frequency of TTK mRNA over expression was detected in 50% of UBC (38/76) by qRT-PCR. Relative mean fold expression of TTK mRNA was found significantly (p < 0.05) higher in muscle-invasive bladder cancer (MIBC) as compared to non-muscle-invasive bladder cancer (NMIBC) patients (8.96 ± 4.51 vs. 5.64 ± 3.53, p = 0.03). Moreover, IHC reveals heterogenous immunostaining pattern of TTK in TCC tissues. The frequency of TTK protein over expression was detected in 56.9% (37 of 65) UBC patients. No significant IHC expression of TTK was detected among adjacent noncancerous tissues (ANCTs) and benign prostatic hyperplasia (BPH) used as control. Collectively our study observations conclude that TTK is a novel cancer/testis antigen (CTA) as a diagnostic marker for early diagnosis of UBC.

A deep learning-based COVID-19 automatic diagnostic framework using chest X-ray images.

The lethal novel coronavirus disease 2019 (COVID-19) pandemic is affecting the health of the global population severely, and a huge number of people may have to be screened in the future. There is a need for effective and reliable systems that perform automatic detection and mass screening of COVID-19 as a quick alternative diagnostic option to control its spread. A robust deep learning-based system is proposed to detect the COVID-19 using chest X-ray images. Infected patient's chest X-ray images reveal numerous opacities (denser, confluent, and more profuse) in comparison to healthy lungs images which are used by a deep learning algorithm to generate a model to facilitate an accurate diagnostics for multi-class classification (COVID vs. normal vs. bacterial pneumonia vs. viral pneumonia) and binary classification (COVID-19 vs. non-COVID). COVID-19 positive images have been used for training and model performance assessment from several hospitals of India and also from countries like Australia, Belgium, Canada, China, Egypt, Germany, Iran, Israel, Italy, Korea, Spain, Taiwan, USA, and Vietnam. The data were divided into training, validation and test sets. The average test accuracy of 97.11 ± 2.71% was achieved for multi-class (COVID vs. normal vs. pneumonia) and 99.81% for binary classification (COVID-19 vs. non-COVID). The proposed model performs rapid disease detection in 0.137 s per image in a system equipped with a GPU and can reduce the workload of radiologists by classifying thousands of images on a single click to generate a probabilistic report in real-time.

CASC5 is a potential cancer-testis gene in human urinary bladder transitional cell carcinoma.

Urinary Bladder cancer (UBC) is a diversified disease with an array of clinicopathological attributes. Several studies have shown that cancer susceptibility candidate 5 (CASC5) plays important roles in various types of malignancies; however its expression and clinical significance in human UBC remain largely unknown. This research study was intended to explore mRNA/protein expression pattern of CASC5 as a member of the cancer-testis (CT) gene family and assess its clinical utility in diagnostic management of patients with UBC. Quantitative real-time PCR (qRT-PCR) and immunohistochemistry (IHC) was employed to appraise the detailed expression profile of CASC5 in patients with UBC. The mRNA over expression of CASC5 was detected in testis tissue and relatively high frequency 59.2% (45 of 76) of CASC5 mRNA was detected in UBC tissues. CASC5 mRNA relative mean fold expression was also significantly (p < 0.01) higher in the muscle-invasive tumor tissues compared to non-muscle-invasive tumor tissues (12.26 ± 9.53 vs. 4.64 ± 2.50, p = 0.005). Heterogeneous staining pattern of CASC5 protein was exclusively detected using IHC. The frequency of CASC5 protein over expression was detected in 67.7% (44 of 65) UBC patients and negative in benign prostatic hyperplasia (BPH). Further, CASC5 protein expression was significantly (p < 0.001) associated with cigarette smoking habit in UBC patients. Our study findings testified that CASC5 over expression among patients with UBC as compared to controls and concludes that CASC5 is a potential CT gene in UBC.

Noninvasive Point-of-Care Nanobiosensing of Cervical Cancer as an Auxiliary to Pap-Smear Test.

A potential cancer antigen (Ag), protein-phosphatase-1-gamma-2 (PP1γ2), with a restricted expression in testis and sperms has been identified as a biomarker specific to cervical cancer (CaCx). Detection of this cancer biomarker antigen (NCB-Ag) in human urine opens up the possibility of noninvasive detection of CaCx to supplement the dreaded and invasive Pap-smear test. A colorimetric response of an assembly of gold nanoparticles (Au NPs) has been employed for the quantitative, noninvasive, and point-of-care-testing of CaCx in the urine. In order to fabricate the immunosensor, Au NPs of sizes ∼5-20 nm have been chemically modified with a linker, 3,3'-di-thio-di-propionic-acid-di(n-hydroxy-succinimide-ester) (DTSP) to attach the antibody (Ab) specific to the NCB-Ag. Interestingly, the addition of Ag to the composite of Ab-DTSP-Au NPs leads to a significant hypsochromic shift due to a localized surface plasmon resonance phenomenon, which originates from the specific epitope-paratope interaction between the NCB-Ag and Ab-DTSP-Au NPs. The variations in the absorbance and wavelength shift during such attachments of different concentrations of NCB-Ag on the Ab-DTSP-Au NPs composite have been employed as a calibration to identify NCB-Ag in human urine. An in-house prototype has been assembled by integrating a light-emitting diode of a narrow range wavelength in one side of a cuvette in which the reaction has been performed while a sensitive photodetector to the other side to transduce the transmitted signal associated with the loading of NCB-Ag in the Ab-DTSP-Au NPs composite. The proposed immunosensing platform has been tested against other standard proteins to ensure noninterference alongside proving the proof-for-specificity of the NCB detection.

FBW7 Inhibits Myeloid Differentiation in Acute Myeloid Leukemia via GSK3-Dependent Ubiquitination of PU.1.

Glycogen synthase kinase 3ß (GSK3ß), an ubiquitously expressed serine/threonine kinase is reported to be overexpressed and hyperactivated in cancers including acute myeloid leukemia (AML) where it promotes self-renewal, growth, and survival of AML cells. Therefore, GSK3ß inhibition results in AML cell growth inhibition and myeloid differentiation. Here we identified master transcription factor PU.1 of monocyte-macrophage differentiation pathway as potential GSK3ß target. We demonstrate that GSK3ß phosphorylates PU.1 at Ser41 and Ser140 leading to its recognition and subsequent ubiquitin-mediated degradation by E3 ubiquitin ligase FBW7. This GSK3-dependent degradation of PU.1 by FBW7 inhibited monocyte-macrophage differentiation. We further showed that a phospho-deficient PU.1 mutant (PU.1-S41, S140A) neither bound to FBW7 nor was degraded by it. Consequently, PU.1-S41, S140A retained its transactivation, DNA-binding ability and promoted monocyte-macrophage differentiation of U937 cells even without phorbol 12-myristate 13-acetate (PMA) treatment. We further showed that FBW7 overexpression inhibited both PMA as well as M-CSF-induced macrophage differentiation of myeloid cell lines and peripheral blood mononuclear cells (PBMC) from healthy volunteers, respectively. Contrarily, FBW7 depletion promoted differentiation of these cells even without any inducer suggesting for a robust role of GSK3ß-FBW7 axis in negatively regulating myeloid differentiation. Furthermore, we also recapitulated these findings in PBMCs isolated from patients with leukemia where FBW7 overexpression markedly inhibited endogenous PU.1 protein levels. In addition, PBMCs also showed enhanced differentiation when treated with M-CSF and GSK3 inhibitor (SB216763) together compared with M-CSF treatment alone. IMPLICATIONS: Our data demonstrate a plausible mechanism behind PU.1 restoration and induction of myeloid differentiation upon GSK3ß inhibition and further substantiates potential of GSK3ß as a therapeutic target in AML.
