Rapidly developing single-cell multi-omics sequencing technologies generate increasingly large bodies of multimodal data. Integrating multimodal data from different sequencing technologies, i.e . mosaic data, permits larger-scale investigation with more modalities and can help to better reveal cellular heterogeneity. However, mosaic integ...
Intestinal bacteria strains play crucial roles in maintaining host health. Researchers have increasingly recognized the importance of strain-level analysis in metagenomic studies. Many analysis tools and several cutting-edge sequencing techniques like single cell sequencing have been proposed to decipher strains in metagenomes. However, strain-leve...
Sequence logos are used to visually display conservations and variations in short sequences. They can indicate the fixed patterns or conserved motifs in a batch of DNA or protein sequences. However, most of the popular sequence logo generators are based on the assumption that all the input sequences are from the same homologous group, which will le...

FAM64A was found to be markedly up-regulated in tumor samples and associated with worse overall survival in multiple cancer types, including breast cancer. However, the functional significance of FAM64A in breast cancer remains largely unknown. In this study, we systematically investigated the expression of FAM64A in multiple public breast cancer d...
Background
Compared with clinically functioning pituitary adenoma (FPA), clinically non-functioning pituitary adenoma (NFPA) lacks of detectable hypersecreting serum hormones and related symptoms which make it difficult to predict the prognosis and monitoring for postoperative tumour regrowth. We aim to investigate whether the expression of selecte...
BACKGROUND/AIM: Cetuximab in combination with chemotherapy is recommended as first-line therapy for metastatic colorectal cancer (mCRC) with wild-type RAS. However, drug resistance to cetuximab exists widely in mCRC and reduces the prognosis of patients. Although some genomic alterations have been demonstrated to drive acquired resistance to cetuxi...
Lung squamous cell carcinoma (LUSC) is the second major type of lung cancer globally. The majority of patients with LUSC are clinically diagnosed at the advanced stages, thus it is urgent to identify suitable prognostic markers for LUSC. B-cell lymphoma 2 (Bcl-2) has been widely studied in non-small cell lung cancer (NSCLC). However, the prognostic...

Gastric cancer is an aggressive cancer that is often diagnosed late. Early detection and treatment require a better understanding of the molecular pathology of the disease. The present study combined data on gene expression and regulatory levels (microRNA, methylation, copy number) with the aim of identifying key genes and pathways for gastric canc...
Both tumor and adjacent normal tissues are valuable in cancer research. Transcriptional response profiles represent the changes of gene expression levels between paired tumor and adjacent normal tissues. In this study, we performed a pan-cancer analysis based on the transcriptional response profiles from 633 samples across 13 cancer types. We obtai...
Breast cancer is a disease with high heterogeneity. Many issues on tumorigenesis and progression are still elusive. It is critical to identify genes that play important roles in the progression of tumors, especially for tumors with poor prognosis such as basal-like breast cancer and tumors in very young women. To facilitate the identification of po...
Background
Gut microbes play a critical role in human health and disease, and researchers have begun to characterize their genomes, the so-called gut metagenome. Thus far, metagenomics studies have focused on genus- or species-level composition and microbial gene sets, while strain-level composition and single-nucleotide polymorphism (SNP) have bee...
Background
Aberrant expression of long non-coding RNAs (lncRNAs) is associated with prognosis of gastric cancer, some of which could be further evaluated as potential biomarkers. In this study, we attempted to identify a specific lncRNA signature to predict the prognosis of gastric cancer.
Material/Methods
The genome-wide lncRNA expression in the...
Protein-coding genes and non-coding RNAs cooperate mutually in cells. Integrative analysis of protein-coding and non-coding RNAs may facilitate characterizing tumor heterogeneity. We introduced integrated consensus clustering (ICC) method to integrate mRNA, miRNA and lncRNA expression profiles of 431 primary clear cell renal cell carcinomas (ccRCCs...
Breast cancer is the most common cancer in women worldwide, identification of new biomarkers for early diagnosis and detection will improve the clinical outcome of breast cancer patients. In the present study, we determined serum levels of vitronectin (VN) in 93 breast cancer patients, 30 benign breast lesions, 9 precancerous lesions, and 30 health...
Loss or attenuated expression of the tumor suppressor gene FHIT is associated paradoxically with poor progression of human tumors. Fhit promotes apoptosis and regulates reactive oxygen species, however, the mechanism by which Fhit inhibits tumor growth in animals remains unclear. In this study, we used a multi-discliplinary approach based on bioinf...

... Most sequencing projects prioritized sample size over high-coverage, perhaps due to the observation that MAG yield per gigabases sequenced per sample peaks at the lower end of library sizes ( Figure S1-2). Some of the most deeply sequenced [23,24] or unusual [25] datasets were analyzed unassembled. The endgame of the reference MAG accumulation process is unclear. ...
... However, they are found in the genome of Arabidopsis thaliana, outside the bacterial domain. This might indicate that YbaB/EbfC orthologs found in bacteria might have been present in the last common ancestor of Eukarya, Archaea, and Bacteria or were acquired by LGT. Figure 2. Sequence length distribution results from MetaLogo [45]. The sequences were grouped with a sequence identity cut-off of 90% using CD-HIT Suite [46], yielding 248 representative proteins. ...
... 14 Another supportive study that investigated stomach susceptibility factors for SARS-CoV-2 showed that IM and H. pylori infection history may be susceptibility factors of SARS-CoV-2, and the mucosal protective agent may be useful for the blockade of SARS-CoV-2 transmission from the stomach to the intestine. 15 Moreover, another study showed that COVID-19 infection was more frequent in males than females, especially between 15-25 years, and also showed COVID-19 patients with positive results to H. pylori have higher levels of neutrophils (p-value= 0.001) and lymphocytes (p-value 0.032) respectively. 16 In general, in Arabic countries, few studies have been conducted to determine whether there is a connection between Covid-19 and H. pylori. ...
... In this regard, several scRNA-seq analyses have profiled the cellular ecosystem of both primary and metastatic GC [128][129][130], providing a good basis to delineate the roles of Hippo in a cell-type specific manner ( Figure 4B). To this end, cell-type-specific depletion of upstream kinases such as Lats1/2 or simple knock-in of a nuclearactivated form of YAP (such as the 5SA mutant) mouse models should be introduced to better explore the pathological modulation of Hippo in each cell type during GC development ( Figure 4B). ...
... As shown in Figure 4E, only miR-21-5p was overlapped among the top 10 miRNAs in OB-exosomes, the top 5 miRNAs in bone marrow cells of radiated mice injected with OB-exosomes and the top 5 miRNAs in FDC-P1 treated with OB-exosomes. MiR-21 has been reported to be involved in anti-apoptotic effects (Xiao et al., 2016;Canfrán-Duque et al., 2017;Cheng et al., 2018;Hu et al., 2020), and the function of miR-21 has been proved in related with hematopoietic apoptosis (Mengjia Hu et al., 2021). Above all, we focused on miR-21 to affirm the effect of OBexosomes on HSC apoptosis. ...
... NF-PitNETs are generally benign tumors in the pituitary gland. However, they are difficult to diagnose at an early stage because there is a lack of detectable hypersecreting serum hormones and specific clinical symptoms of NF-PitNETs at the early stage compared to FPAs [11]. NF-PitNETs are commonly detected according to some non-specific clinical symptoms such as headache, vision loss, or hypopituitarism. ...
... 13 Abnormal expression of FAM64A has been reported in several types of cancer such as prostate cancer, breast cancer, and pancreatic cancer. [14][15][16] However, the potential role of FAM64A in HNSCC is unknown. In addition, understanding of the detailed molecular mechanism accounting for the tumor promoting role of FAM64A is still in its infancy. ...
... Several studies postulate that they also act as effective biomarkers to chemotherapy resistance in mCRC patients. 20, 21 Yokoyama et al 22 suggest the lncRNA H19 and UAC1 were associated with the 5-FU resistance in the rectal cancer. Similarly, Li et al 23 report that mRNAs and lncRNAs biomarkers can effectively predict NCRT response in LARC patients. ...
... The application of a classical method of data normalization, z-score transformation, provides a way of standardizing data across a wide range of experiments and allows the comparison of microarray data independent of the original hybridization intensities. The z-score it is considered a reliable procedure for this type of analysis and can be considered a state-of-the-art methods, as demonstrated by the numerous bibliography [54][55][56][57][58][59][60][61][62][63][64][65] . The efficiency of RETNLB was assessed by the receiver operating characteristic (ROC) curve analyses. ...
