    The imminent role of microRNAs in salivary adenoid cystic carcinoma
    (Neoplasia Press, Inc., 2022-11-04T00:00:00) Kumar, Pawan; Kumawat, Ram Kumar; Uttam, Vivek; Behera, Alisha; Rani, Medha; Singh, Neha; Barwal, Tushar Singh; Sharma, Uttam; Jain, Aklank
    Unfortunately, despite the severe problem associated with salivary adenoid cystic carcinoma (SACC), it has not been studied in detail yet. Therefore, the time has come to understand the oncogenic cause of SACC and find the correct molecular markers for diagnosis, prognosis, and therapeutic target to tame this disease. Recently, we and others have suggested that non-coding RNAs, specifically microRNAs and long non-coding RNAs, can be ideal biomarkers for cancer(s) diagnosis and progression. Herein, we have shown that various miRNAs, like miR-155, miR?103a?3p, miR-21, and miR-130a increase the oncogenesis process, whereas some miRNAs such as miR-140-5p, miR-150, miR-375, miR-181a, miR-98, miR-125a-5p, miR-582-5p, miR-144-3p, miR-320a, miR-187 and miR-101-3p, miR-143-3p inhibit the salivary adenoid cystic carcinoma progression. Furthermore, we have found that miRNAs also target many vital genes and pathways like mitogen-activated protein kinases-snail family transcriptional repressor 2 (MAPK-Snai2), p38/JNK/ERK, forkhead box C1 protein (FOXC1), mammalian target of rapamycin (mTOR), integrin subunit beta 3 (ITGB3), epidermal growth factor receptor (EGFR)/NF-?B, programmed cell death protein 4 (PDCD4), signal transducer and activator of transcription 3 (STAT3), neuroblastoma RAS (N-RAS), phosphatidylinositol-3-kinase (PI3K)/Akt, MEK/ERK, ubiquitin-like modifier activating enzyme 2 (UBA2), tumor protein D52 (TPD52) which play a crucial role in the regulation of salivary adenoid cystic carcinoma. Therefore, we believe that knowledge from this manuscript will help us find the pathogenesis process in salivary adenoid cystic carcinoma and could also give us better biomarkers of diagnosis and prognosis of the disease. � 2022

    Impact of noncoding RNAs on cancer directed immune therapies: Now then and forever
    (John Wiley and Sons Inc, 2022-04-30T00:00:00) Roy, Roshan Kumar; Yadav, Rakhi; Sharma, Uttam; Wasson, Mishi Kaushal; Sharma, Ashok; Tanwar, Pranay; Jain, Aklank; Prakash, Hridayesh
    Accumulating evidence demonstrates that the host genome's epigenetic modifications are essential for living organisms to adapt to extreme conditions. DNA methylation, covalent modifications of histone and interassociation of noncoding RNAs facilitate the cellular manifestation of epigenetic changes in the genome. Out of various factors involved in the epigenetic programming of the host, noncoding RNAs (ncRNAs) such as microRNA (miRNA), long noncoding RNA (lncRNA), circular RNA, snoRNA and piRNA are new generation noncoding molecules that influence a variety of cellular processes like immunity, cellular differentiation and tumor development. During tumor development, temporal changes in miRNA/lncRNA rheostat influence sterile inflammatory responses accompanied by the changes in the carcinogenic signaling in the host. At the cellular level, this is manifested by the upregulation of inflammasome and inflammatory pathways, which promotes cancer-related inflammation. Given this, we discuss the potential of lncRNAs, miRNAs, circular RNA, snoRNA and piRNA in regulating inflammation and tumor development in the host. � 2022 UICC.

    Bio-analytical applications of nicking endonucleases assisted signal-amplification strategies for detection of cancer biomarkers -DNA methyl transferase and microRNA.
    (Elsevier, 2019) Mittal, S; Thakur, S; Mantha, A. K.; Kaur, H.
    The low concentrations of cancer biomarkers in the blood have limited the utility of quantitative bioassays developed for the purpose. The advent of nicking endonucleases (NEases) as signal amplification tools have greatly enhanced the detection efficiency and provided a multi-optional platform to design target specific detection methods. The present review focuses on the prominent features of NEases, modified DNA probes (such as hairpin (HP) probes, molecular beacons, and G- quadruplex) that mediate cyclic cascade and role of helper enzymes. Application of NEase assisted signal amplification (NESA) has been discussed for diagnosis of two prominent cancer biomarkers viz. DNA methyl transferase (Dam MTase) and microRNA (miRNA). NESA mediated techniques such as rolling circle amplification (RCA), strand displacement amplification (SDA) and isothermal exponential amplification (EXPAR), have been compared in light of their future applications in clinical diagnosis. Significance of nanomaterials to achieve further amplification and NESA assays for simultaneous detection of miRNAs has also been conversed. It is anticipated that the information gained from the analyses of the prospects and limitations of NESA-based assays will be useful towards understanding the applications, and improvement of efficient isothermal exponential amplification strategies for highly sensitive and selective detection of cancer biomarkers.
