USP10 deubiquitinates and stabilizes CD44 leading to enhanced breast cancer cell proliferation, stemness and metastasis.

Despite extensive research, strategies to effectively combat breast cancer stemness and achieve a definitive cure remains elusive. CD44, a well-defined cancer stem cell (CSC) marker is reported to promote breast cancer tumorigenesis, metastasis, and chemoresistance. However, mechanisms leading to its enhanced expression and function is poorly understood.

Nemo-like kinase blocks myeloid differentiation by targeting tumor suppressor C/EBPα in AML.

CCAAT/enhancer-binding protein α (C/EBPα), a key myeloid transcription factor, drives myeloid differentiation from blast cells by regulating the expression of granulocyte colony stimulating factor receptor and C/EBPε as required for promoting granulocyte differentiation. Here, we show that serine/threonine-protein kinase NLK, also known as Nemo-like kinase, physically associates with C/EBPα and phosphorylates it at multiple sites, including Ser21, Thr226, Thr230 and S234, leading to its ubiquitin-mediated degradation. Individual phospho-point mutants of C/EBPα could be phosphorylated by NLK, but a mutant with all phosphorylatable residues replaced by alanine resisted phosphorylation and degradation by NLK, as did the single point mutants.

Long-term clinical outcomes of male breast cancer patients treated with curative intent by trimodality therapy at an academic university hospital in India.

Introduction: Male breast cancer is rare and accounts for less than 1% of all breast cancer cases worldwide.

Methods: This retrospective cohort study included all patients of invasive male breast cancer treated with curative intent by a trimodality approach via a multidisciplinary team at an academic university hospital in India between 2009 and 2023. Records were identified from a prospectively maintained database.

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.

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.

Radio frequency analysis of partially grafted immediate dental implant with and without use of static magnetic field: An study.

Background: Replacement of missing teeth with dental implants represents one of the most successful treatment modalities in modern dentistry. Patients desire for a shorter treatment time has made clinicians to attempt loading implants early or immediately after placement. The primary stability is determined by density and mechanical properties of the bone, the implant design, edentulous site complications, and the surgical technique.

Interaction of cytochrome P450s with environmental risk factors increases their expression and risk to head and neck cancer.

To investigate the role of interaction of tobacco metabolizing polymorphic cytochrome P450s (CYPs) and glutathione S-transferase M1 (GSTM1) with environmental risk factors in modifying the susceptibility to head and neck squamous cell carcinoma (HNSCC), a case-control study with 1250 proven cases of HNSCC and equal number of healthy controls was planned. A small but significant increase in the risk to HNSCC (1-2 fold) in the cases with variant genotypes of CYPs (1A1 or 1B1 or 2E1) increased several folds (up to 13 fold) in regular tobacco or alcohol users. This several fold increase in risk could be due to more than multiplicative interaction observed between the risk genotypes of CYPs and tobacco or alcohol.

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

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.

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.

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.

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.
