**Detailed Description:** 1. INTRODUCTION Background: Colorectal cancer (CRC) has been identified as a major public health concern given its high incidence and mortality rates (1). In 2020, CRC was the third-most prevalent malignancy after breast and lung cancer, accounting for 10% of new cases and ranking second in terms of mortality with 9.4% of deaths (2). Unfortunately, by year 2030, more than 2.2 million new cases and 1.1 million fatalities from CRC are globally anticipated (3).

Problem: Despite significant improvements in CRC surgical or radiological interventional treatment approaches with neo-adjuvant therapies, patients' prognosis remains bleak (4,5). Metastases and post-surgical tumor recurrence are prevalent, particularly, in more advanced cancer cases (6), which may account for the increased number of cases and fatalities prediction, being against the national efforts for achieving Egypt Vision 2030 implementing SDGs.

Problem statement: Conventionally used CRC prognostic markers for monitoring treatment outcome and pointing to cancer recurrence are carbohydrate antigen 19.9 (CA19.9) and/or carcinoembryonic antigen (CEA) that are not that sensitive (7) per patients subclassification or stratification related to CRC pathological characteristics for more efficient and earlier prognosis. Thence, a growing demand for sensitive and precise bio-molecular marker(s) better correlating with CRC prognostic markers and/or CRC clinical outcome (8), that is if successful would constitute the bases for "Better Health" SDG#3 and less cancer recurrence and, therefore, less mortality.

Liquid biopsies are used for cancer diagnosis or prognosis, like breast cancer, leukemia, liver cancer or CRC, via measurement of tumor-derived bio-molecular markers including circulating ncRNAs including long non-coding RNAs (lncRNAs), microRNA, exosomal ncRNAs, oncogenes or tumor suppressor genes, and their mutations, tumor-related-cytokines, and down-stream target proteins (9-22).

After extensive literature search and mining to mind-the-research-gap(s) for better "Cancer Epigenetics Study; a Step-toward ncRNA-Precision" we have chosen, in the current work, two notch-related lncRNAs to study in relation-to-CRC prognosis.

Notch-signaling pathway is an ubiquitous cascade within species to control a broad variety of biological events, including cell division, proliferation, and cell death (23,24). Recent investigations have revealed the fundamental role of Notch-cascade in CRC evolution (25). Intestinal epithelial cells' homeostatic self-renewal and tumor-promoting transformation can both be managed by Notch signaling (26). Stimulation of Notch-cascade can be epigenetically triggered by dysregulated non-protein coding RNAs' (ncRNAs) expressions (27); a hot area of research nowadays to figure out the impact of Notch-related ncRNAs on CRC risk and/or progression.

The significant utility of tumor-expressed Notch-associated lncRNAs as prognostic malignancy indicators proves how they are connected to carcinogenesis or metastasis and therefore, reflect the outcome(s) in different cancer types including CRC (28-31).

Small Nucleolar RNA Host Gene3 (SNHG3) is 4950bp lncRNA situated on chromosome 1p35.3 (32). In breast cancer, upregulated SNHG3 triggers Notch system activation as a result of its competitive binding to human homo sapiens (hsa) micro-RNA (miR) hsa-miR-154-3p exacerbating proliferation and metastasis of cancer cells (33). Moreover, SNHG3 positively regulates Notch1 expression in ovarian cancer through hsa-miR-139-5p suppression, accelerating tumor cells' proliferation and migration (34). SNHG3 exerted a carcinogenic role in prostate cancer, osteosarcoma, glioma, gastric cancer, laryngeal cancer, bladder cancer, and CRC (32). Huang et al. reported SNHG3 elevated expression in CRC cells and tissues, stimulating cancer progression through sponging hsa-miR-182-5p (35). Therefore, SNHG3 is considered as a malignancy enhancer that regulates Notch system in various cancer types.

Leukemia-associated nc-insulin-like growth factor1 receptor (IGF1R)-Activator RNA1 (LUNAR1) serves as a downstream target of Notch-signaling, in the same time LUNAR1 acts through Notch-signaling stimulation. LUNAR1 is a transcript of 491 nucleotides (nt) gene on chromosome 15q26.3 with four exons and poly (A) tail (36). LUNAR1 was identified to be elevated in CRC tissues, triggered by Notch1 stimulation, accelerating CRC progression via retaining IGF1R expression (37), being a positive regulator of cell division Aim of the study: Per, few research publications on both notch-related lncRNAs, SNHG3 and LUNAR1, in CRC prognosis or CRC risk assessment as well as patients' stratification based on clinico-pathological characteristics, therefore, assessment of the clinical utility of SNHG3 and LUNAR1 lncRNAs fold change expressions in CRC patients' peripheral blood liquid biopsy is alarming (as step toward implementing ncRNA precision) Study objective(s) to assess, first, the expression level and pattern of Notch-associated lncRNAs SNHG3 and LUNAR1 in peripheral blood liquid biopsy, polled from treatment-naïve Egyptian CRC patients' cohort, compared to age-matched and sex-matched apparently healthy volunteer subjects as controls. Second, to evaluate lncRNAs SNHG3 and LUNAR1 expression usefulness as sensitive, non-invasive prognostic bio-molecular marker(s) for CRC monitoring. Third, to investigate the correlation between SNHG3 and LUNAR1 expression with CRC clinic-pathological features. Finally, to explore the relevance of the investigated lncRNAs for CRC patients' clinical features outcomes assessment. All these objectives to be confirmed or ruled out by in silico analysis and bioinformatics databases search SUBJECTS 2.1. Sample Size and Power of the Study. In accordance with prior reference studies (36,38) the sample size was estimated utilizing sample size online calculator https://riskcalc.org/samplesize/# for comparison of the area under the curve (AUC) with a null hypothesis value (done January, 2021) through using two-sided significance level of 0.05 and the power (1-beta) of 0.95 as the two-sided confidence level of 95%.

Blood Samples From CRC patients and healthy volunteers, five milliliters of peripheral venous blood fluid biopsy were collected and stored in clot-activating polymer gel vacutainers (Greiner Bio-One GmbH, Australia). The samples were centrifuged in vacutainers at a speed of 4000 rpm for ten minutes at room temperature (25°C). The obtained serum was aliquoted and stored at -80°C in RNAse-free Eppendorf tubes.

3.2.1. Total RNA Extraction Using the miRNeasy Mini kit (Cat. No. 217004; Qiagen, Hilden, Germany), total RNA was isolated from sera in accordance with the protocol's instructions. Aliquots of the extracted RNA were kept at -80°C after being dissolved in 30 μl of RNase-free water.

3.2.2. Quantitation of purified RNA Using a NanoDrop®-1000 spectrophotometer (Thermo Scientific, Wilmington, DE, USA), the isolated RNA's purity and concentration are evaluated. RNA's quantity was determined in the sample utilizing absorbance at 260 nm (A260 = 1 → 44 ng/μl). In addition, the purity of RNA was evaluated utilizing A260/280 nm ratios. The acceptable 260/280 ratio ranges from 1.8 to 2.1, whereas the 260/230 ratio is more than 1.7.

3.2.3. Reverse Transcription Complementary DNA (cDNA) synthesis was carried out using the High-Capacity cDNA Reverse Transcription Kit with RNase Inhibitor (Cat. No 4374966, Applied Biosystems, ThermoFisher Scientific, USA) according to the manufacturer's regulations. In a 20 µl reaction volume, reverse transcription was carried out at 25 °C for 10 minutes, 37 °C for 120 minutes, and then underwent heat inactivation for 5 minutes at 85 °C. The produced cDNA was maintained at -80°C till further investigations.

3.2.4. Expression Measurement of lncRNAs Using Quantitative Real-Time Reverse Transcription Polymerase Chain Reaction (qRT-PCR) QRT-PCR was carried out in a 20 µl reaction using the TaqMan® Gene Expression Master Mix (Cat. No 4370048, Applied Biosystems, ThermoFisher Scientific, USA). In order to determine the expression levels of lncRNAs SNHG3 and LUNAR1, TaqMan gene expression assays for human SNHG3 (Hs05055352_s1, Cat. No 4448892, ThermoFisher Scientific, USA) and human LUNAR1 (Hs03829521_s1, Cat. No 4426961, ThermoFisher Scientific, USA) were used and the TaqMan gene expression assay for human glyceraldehyde 3-phosphate dehydrogenase (GAPDH) (Cat. No 4326317E, ThermoFisher Scientific, USA) was used as an endogenous standard to normalize the values. The reaction was conducted using the StepOne™ qRT-PCR technique (Applied Biosystems, CA, USA). The thermal cycling strategy was as follows: a stage of initial uracil-N-glycosylase (UNG) incubation at 50°C for 2 minutes, followed by activation step lasting 10 minutes at 95 °C proceeded by 40 cycles of denaturation for 15 sec at 95 °C, annealing and extending for 1 minute at 60 °C.

Per the manufacturer, the assay "limit of detection" (LoD) can detect cDNA template from 1pg to 100 ng in nuclease free water.

The cycle threshold (Ct) technique as a fold change (2-ΔΔCt) was used to calculate and normalize the lncRNAs expression levels, utilizing GAPDH as the housekeeping gene. ΔCt was obtained by subtracting the Ct values of GAPDH from either SNHG3 or LUNAR1 Ct values (49), where; ΔΔCt = ΔCtCRC samples - ΔCthealthy control samples 3.2.5. CEA and CA19-9 determination by electrochemiluminescence immunoassay One portion of the obtained sera was utilized for the purpose of determining CEA and CA19-9 tumor markers. Electrochemiluminescence immunoassay utilizing Cobas® e 602 developed by Roche Diagnostics, GmbH, Germany was used to determine the serum concentrations of CEA (Cat. No 11731629 322) and CA19.9 (Cat. No 11776193500), according to the manufacturer's protocol.

3.2.6. Routine biochemical testing results record from patients' files Liver function tests; aspartate aminotransferase (AST) and Alanine aminotransferase (ALT) as well as serum creatinine and serum urea levels, hemoglobin (Hgb), platelet count, lymphocytes count, and prothrombin time (PT) were all gathered from patients' files.

3.2.7. Ratios and Indices In meters, participants' heights and in kilograms their weights were recorded, to calculate Body mass index (BMI in kg/m2) where overweight subjects have BMI of 25-29.9 kg/m2, 30 kg/m2 or over are obese, while 18.5-24.9 kg/m2 is indicative of normal weight, https://www.nhlbi.nih.gov/health/educational/lose_wt/BMI/bmicalc.htm The immune response-related inflammation indicator biomarker able to predict the accompanying inflammatory disorder severity is the platelet-to-lymphocytes ratio (PLR) (10,50).

3.3. Statistical Analysis With the aid of GraphPad Prism® version 9.01 (GraphPad Software, San Diego, CA, USA, SPSS 23.0 (statistical package for social studies software) (IBM, Armonk, NY), MedCalc Statistic Software version 19.1 (MedCalc Software by Ostend, Belgium), and Microsoft Office Excel 2019, statistical analysis was carried out.

Chi-square test (χ2) was utilized to assess the associations between participants' characteristics and the groups. The Shapiro-Wilk normality test as well as Kolmogorov-Smirnov test were applied to determine the pattern of the normal distribution for the both groups and subgroups of data. Data was expressed as mean ±SD when it passed the normality test. Student's (t) test was utilized to determine any significant differences between two normally distributed groups. Additionally, one-way ANOVA (F) followed by post hoc Tukey's multiple comparison test was used, when required, to determine significant variations between multiple groups. While, the data that didn't pass the normality test was expressed as median (interquartile range) (IQR) (25th percentile-75th percentile). The Mann-Whitney (U) test was used to pinpoint the significant changes between two sets of participants. Moreover, the Kruskal-Wallis (H) test and consequently Dunn's multiple comparison test were used, when needed, to determine whether there were statistically significant differences between different groups.

The receiver operating characteristic (ROC) curve as well as AUC were implemented to evaluate the abilities of serum lncRNAs SNHG3 and LUNAR1 for discrimination between groups and with groups for subgrouping identification. The best cut-off, sensitivities (SNs), specificities (SPs) as well as negative and positive predictive values NPVs and PPVs, respectively, were all determined using the ROC curve, with AUC estimated range from 0 to 1.

Negative likelihood ratios (LRs) are employed in medical testing to evaluate the marker discriminative efficiency. The ratio, which denotes the likelihood that a person has the disease or condition, confirms the SNs and SPs identified by the ROC curve. SN and SP provide a different meaning for the LR, with negative LR equal to (100-SN)/SP.

Multiple regression models were used to assess the influence of the participants demographic and patients' clinicopathological data (as independent factors) on the expression levels of the lncRNAs SNHG3 and LUNAR1 that we considered as the dependent variables. Correlation between numerous variables was assessed using Spearman's correlation coefficient (r). Statistical analysis tests are set significant when the two-tailed p-value is \<0.05 (\*).
