Abstract
BACKGROUND AND AIMS Coronavirus disease 2019 (COVID-19) vaccines were rapidly implemented globally and vaccine-associated immune-related hepatitis was recently reported. We aim to investigate its impact in regions endemic of chronic hepatitis B (CHB). METHODS We retrospectively collected patients who developed hepatitis within 90 days after COVID-19 vaccination in Taiwan. The mechanisms of hepatitis included vaccine induced liver injury (VILI) and immune-related hepatitis, which are direct liver injuries defined as aspartate or alanine aminotransferase (AST or ALT) increased ≥ 5-fold upper limit of normal (ULN) and/or AST or ALT ≥ 3-fold of ULN with concurrent total bilirubin ≥ 2-fold of ULN. Indirect liver injury due to HBV reactivation was defined as HBsAg reverse seroconversion or significant rise in HBV DNA level. The demographics, clinical data, and course of hepatitis were compared statistically. RESULTS Twenty-five patients were included with a median age of 54. The culprit vaccines were ChAdOx1 nCoV-19 (n = 9), mRNA-1273 (n = 12), and BNT162b2 (n = 4). The characteristics of hepatitis were comparable regardless of vaccine subtypes. The median onset of hepatitis was 25 days post vaccination, with a peak of 10-fold ALT-increase. The etiologies included HBV reactivation (n = 10), VILI (n = 10), and immune-related hepatitis (n = 5). HBV reactivation accounts for 90% of vaccine-induced hepatitis in patients of CHB (n = 10), and two patients died. Patients with initial AST levels >500 U/L increased 27-fold risks of liver injury greater than moderate severity compared with those without. CONCLUSION COVID-19 vaccine induced hepatitis is a clinical significant complication, and HBV reactivation may account for a possible mechanism.

Abstract
Objective: To investigate the safety and feasibility of Da Vinci robot-assisted pylorus and vagus nerve-preserving partial gastrectomy for gastric cancer. Methods: In this study, descriptive case series method was used to retrospectively analyze the data of 3 patients with gastric cancer who underwent Da Vinci robot-assisted pylorus and vagus nerve-preserving partial gastrectomy in the First Affiliated Hospital of Dalian Medical University from December 2020 to February 2021. The linear layout was adopted for the setting of trocar, and the co-axial direction was the line connecting the umbilicus and splenic hilum. The inferior pyloric arteries and veins need to be preserved. The center was the bifurcation of the right gastroepiploic vessel and the inferior pyloric vessel. Dissection and exposure were performed from the upper, lower, right and left sides, and ventral and dorsal sides to complete the dissection of the inferior pyloric lymph nodes. The superior border of the pancreas was treated by the right diaphragmatic crus approach, the left retroperitoneal approach and the esophageal approach to determine the distribution of the posterior vagal trunk and its branches, and to determine the anatomical relationship with the left gastric artery. The left gastric artery was cut off while the celiac branch of vagus nerve and cardia branch of left gastric artery were preserved. Lymph node dissection was performed on the lateral side of nerve fibers around the blood vessels. Result: All the 3 patients successfully completed the robotic surgery without conversion to laparoscopy or laparotomy. The operation time was (340.0±26.4) (300-390) minutes, the intraoperative blood loss was (13.3±3.3) (10-20) ml, the number of dissected lymph nodes was 26.7±3.9 (19-32), the length of pylorus canal preserved was (3.3±0.3) (3-4) cm, the distal margin was (2.3±0.3) (2-3) cm, and the proximal margin was (3.0±0.6) (2-4) cm. No postoperative complications occurred in all the 3 patients. The first flatus time was 2-3 days after operation, and the postoperative hospital stay was 6-7 days. The operation cost of the 3 patients was (40±7) (33-53) thousand yuan. Conclusion: Da Vinci robot-assisted pylorus and vagus nerve-preserving partial gastrectomy is safe and feasible.

Abstract
Objective: To explore the impact of surgical treatment on the life quality of patients with locally advanced hypopharyngeal carcinoma. Methods: A retrospective analysis of the clinical data of 21 patients with advanced hypopharyngeal carcinoma who underwent surgery at the Shenzhen Hospital of Chinese Academy of Medical Sciences Cancer Hospital from January 1, 2017 to December 31, 2019 was conducted. There were 3 patients with recurrence after radiotherapy and chemotherapy, 4 cases of postoperative recurrence, 3 cases of postoperative recurrence after radiotherapy and chemotherapy. Three cases were hypopharyngeal carcinoma with esophageal carcinoma and 8 cases were stage Ⅳ hypopharyngeal carcinoma. Among them, 3 cases were repaired by stomach, 4 cases by free jejunum, 2 case by great saphenous vein for internal carotid artery, 1 case by artificial blood vessel for internal carotid artery, 5 cases by transfer of pectoralis major musculocutaneous flap and 2 cases by transfer of submental island flap. The 21 patients were scored using the European Cancer Research and Treatment Organization's Quality of Life Head and Neck Tumor Special Scale (EORTC QLQ-H&N35) on the 3 months before and after surgery, and the changes in postoperative life quality were compared. Results: The preoperative life quality score of 21 patients was (56.86±7.95) points and life quality score of 3 months after operation was (50.93±7.91) points. The postoperative life quality was significantly improved (P<0.05). The improvement of the postoperative life quality of the patients mainly included the improvements of the head and neck pain, swallowing function, diet, taking analgesics and indwelling nasal feeding tubes. The preoperative scores were (7.58±1.56) points, (8.46±1.63) points, (7.94±0.43) points, (1.76±0.12) points and (1.86±0.28) points, respectively, while the scores of 3 months after operation were (5.02±1.23) points, (6.28±1.58) points, (6.34±0.36) points , (1.12±0.08) points and (1.24±0.18) points, the differences were statistically significant (all P<0.05). Conclusion: The flexible selection of flap repair for locally advanced hypopharyngeal carcinoma is still feasible, and surgery can improve the life quality of patients.

Abstract
Objective: To explore the association between preeclampsia/eclampsia and maternal and fetal angiotensinogen SNPs. Methods: From January 2008 to October 2015, a case-parents/mother-control designed study was conducted among 347 preeclampsia/eclampsia cases and 700 controls to collect related information on their demographic characteristics and to detect the related angiotensinogen SNPs' genotypes. Both log-linear and unconditional logistic regression methods were employed to investigate the genetic effects of maternal/fetal angiotensinogen SNPs on preeclampsia/eclampsia. Multivariate binary unconditional logistic regression model and covariance were used to analyze the relationship between BMI before pregnancy, weight gain during pregnancy and overweight and obesity in preschool children. Results: Both fetal angiotensinogen rs3789679 GA and AA genotype were associated with the reduced risks of preeclampsia/eclampsia, with ORs as 0.73 (95%CI: 0.55-0.96) and 0.62 (95%CI: 0.39-0.98), respectively. For fetal angiotensinogen rs2493132, individuals that carrying the TT genotype, presented a positive association with the risk of preeclampsia/eclampsia, with OR as 1.60 (95%CI: 1.08-2.37). However, these associations were not statistically significant after the correction of the false discovery rate. It was observed that fetal rs3789679 could reduce the risk of preeclampsia/eclampsia (OR=0.73, 95%CI: 0.55-0.96) under the dominant model (GA+AA/GG) while fetal rs2493132 increased the risk of preeclampsia/eclampsia (OR=1.66, 95%CI: 1.13-2.44) under the recessive model (TT/CC+CT). Maternal rs5051 presented an association with preeclampsia/eclampsia (OR=1.33, 95%CI: 1.01-1.76) under the dominant model (TC+CC/TT). Conclusions: Results from the dominant model showed that both fetal rs3789679 GA and AA genotype reduced the risk of preeclampsia/eclampsia and maternal rs5051 TC while CC genotype increased the risk of preeclampsia/eclampsia. Fetal rs2493132 TT genotype seemed to be associated with the risk of preeclampsia/eclampsia under the recessive model.

Abstract
BACKGROUND Bevacizumab, a recombinant humanized monoclonal antibody that blocks angiogenesis by inhibiting vascular endothelial growth factor A, was described to be effective in the treatment of recurrent or platinum-resistance ovarian cancer. The present retrospective study was performed to further evaluate the clinical efficacy and toxicity of bevacizumab in the treatment of Chinese recurrent ovarian cancer patients who had been previously treated by platinum-based chemotherapy. MATERIALS AND METHODS We reviewed the hospital database and finally included 26 recurrent ovarian cancer patients who were treated with bevacizumab combined with gemcibabine or paclitaxel or single agent. All included patients received >3 cycle of bevacizumab treatment. The tumor response, overall survival, and toxicities were documented. RESULTS Under the treatment of bevacizumab combined with gemcibabine or paclitaxel, 2 complete response (7.7%), 8 partial response (30.8%), 7 stable disease (26.9%) and 9 progression disease (34.6%) was documented with the objective response rate of 38.5% and disease control rate of 65.4%. The median overall survival from the first application of bevacizumab was 15.3 months [Figure 1] for all of the 26 patients. The median overall survival time was 16.2 and 14.0 months for bevacizumab + gemcitabine and bevacizumab + paclitaxel treatment schedule respectively. The overall survival was not different between bevacizumab + gemcitabine and bevacizumab + paclitaxel treatment regimen hazard ratio = 0.80 (95% confidence interval: 0.32-2, P = 0.64). The hypertension and proteinuria were the major bevacizumab related toxicities. CONCLUSIONS Bevacizumab combined with gemcibabine or paclitaxel was a promising treatment schedule for platinum-resistance recurrent ovarian cancer.

Abstract
OBJECTIVE Helicobacter pylori infection places a heavy burden on medical and economic resources. Standard diagnosis requires the presence of established H. pylori gastric disease. STUDY DESIGN AND SETTING A multicenter screening trial assessing 2 immunochromatographic H. pylori antigen oral tests was carried out with 201 participants. The analysis also included a urea breath test (UBT), a Campylobacter-like organism test, silver stain, culture, serology, and stool tests. RESULTS The participants were grouped into UBT positive (UBT+) and UBT negative (UBT-) people, using conventional methods with congruent clusters based on p values from McNemar's paired χ2 analysis and 95% CI estimates. Both oral tests were also positive in 82% of the seropositive UBT- people. However, oral antigen and seroprevalence divided UBT- people into 2 statistically separate CI subgroups: the UBT- symptomatic (highly positive) group and the UBT- asymptomatic (mostly negative) group. 90.5% of all people whose oral tests were both negative were also UBT-. CONCLUSIONS Saliva H. pylori antigen is an important indicator in UBT- asymptomatic patients. Currently, its clinical significance remains uncertain, but saliva may be a reservoir from where H. pylori is transmitted to the stomach. In symptomatic patients, it is strongly associated with stomach infection.

Abstract
As the exponential growth of DNA sequence information in databases continues, the task of converting this deposited information into knowledge becomes more dependent on integrative sequence analysis and visualization tools. PANORAMA is an Internet-accessible software package that performs a variety of informatics analyses on a given DNA sequence and returns a visual and interactive representation of the results. Its design is modular, so that further sequence analysis tools can be integrated with minimal effort. The utility of PANORAMA is demonstrated in the analysis of 650 kb of human genomic DNA from chromosome region 3p21.3, a region of potential tumor suppressor genes involved in lung cancer, breast cancer, and other forms of cancer. PANORAMA aided in the discovery of genes and alternate splice forms of known exons, in the demarcation of intron-exon boundaries, and in the identification of promoter regions and polymorphisms, all of which contributed to a better understanding of the region. PANORAMA is available on the World Wide Web at http://atlas.swmed.edu.

Abstract
The fly Drosophila melanogaster is one of the most intensively studied organisms in biology and serves as a model system for the investigation of many developmental and cellular processes common to higher eukaryotes, including humans. We have determined the nucleotide sequence of nearly all of the approximately 120-megabase euchromatic portion of the Drosophila genome using a whole-genome shotgun sequencing strategy supported by extensive clone-based sequence and a high-quality bacterial artificial chromosome physical map. Efforts are under way to close the remaining gaps; however, the sequence is of sufficient accuracy and contiguity to be declared substantially complete and to support an initial analysis of genome structure and preliminary gene annotation and interpretation. The genome encodes approximately 13,600 genes, somewhat fewer than the smaller Caenorhabditis elegans genome, but with comparable functional diversity.

Abstract
The 3p- syndrome results from deletion of a terminal segment of the short arm of one chromosome 3 (3p25-->pter), and is characterized by multiple congenital anomalies and mental retardation. Due to its variable expression, it is assumed this disorder is a contiguous gene syndrome with an undefined number of genes contributing to the phenotype. In an effort to discover genes contributing to mental defects in 3p- syndrome, we determined whether the CALL gene, mapped to 3p26.1 and coding for a neural recognition molecule, is deleted in a boy with this disorder. We found that the break in this patient is distal to the VHL gene, removing D3S18 and the CALL loci. The deletion of one copy of the CALL gene might be responsible for mental defects in patients with 3p- syndrome. Am. J. Med. Genet. 86:482-485, 1999. Published 1999 Wiley-Liss, Inc.

Abstract
A number of genes underlie the molecular bases of intelligence. Among these is probably CALL, a novel member of the L1 gene family of neural cell adhesion molecules. By using the single strand conformation polymorphism (SSCP) protocol, we screened the regions of the CALL gene corresponding to the 5' and 3' untranslated regions (UTRs) of the CALL mRNA, searching for polymorphisms that could be useful in association studies in the field of intelligence. We report the finding of T-to-A and T-to-C single nucleotide polymorphisms (SNPs) in the 3' UTR of CALL. These SNPs have an index of heterozygosity of 0.13 and 0.10, respectively. Research is in progress to understand the association between these variants and high IQ.

Abstract
To discover genes involved in von Hippel-Lindau (VHL)-mediated carcinogenesis, we used renal cell carcinoma cell lines stably transfected with wild-type VHL-expressing transgenes. Large-scale RNA differential display technology applied to these cell lines identified several differentially expressed genes, including an alpha carbonic anhydrase gene, termed CA12. The deduced protein sequence was classified as a one-pass transmembrane CA possessing an apparently intact catalytic domain in the extracellular CA module. Reintroduced wild-type VHL strongly inhibited the overexpression of the CA12 gene in the parental renal cell carcinoma cell lines. Similar results were obtained with CA9, encoding another transmembrane CA with an intact catalytic domain. Although both domains of the VHL protein contribute to regulation of CA12 expression, the elongin binding domain alone could effectively regulate CA9 expression. We mapped CA12 and CA9 loci to chromosome bands 15q22 and 17q21.2 respectively, regions prone to amplification in some human cancers. Additional experiments are needed to define the role of CA IX and CA XII enzymes in the regulation of pH in the extracellular microenvironment and its potential impact on cancer cell growth.

Abstract
To discover genes contributing to mental retardation in 3p- syndrome patients we have used in silico searches for neural genes in NCBI databases (dbEST and Uni-Gene). An EST with strong homology to the rat CAM L1 gene subsequently mapped to 3p26 was used to isolate a full-length cDNA. Molecular analysis of this cDNA, referred to as CALL (cell adhesion L1-like), showed that it is encoded by a chromosome 3p26 locus and is a novel member of the L1 gene family of neural cell adhesion molecules. Multiple lines of evidence suggest CALL is likely the human ortholog of the murine gene CHL1: it is 84% identical on the protein level, has the same domain structure, same membrane topology, and a similar expression pattern. The orthology of CALL and CHL1 was confirmed by phylogenetic analysis. By in situ hybridization, CALL is shown to be expressed regionally in a timely fashion in the central nervous system, spinal cord, and peripheral nervous system during rat development. Northern analysis and EST representation reveal that it is expressed in the brain and also outside the nervous system in some adult human tissues and tumor cell lines. The cytoplasmic domain of CALL is conserved among other members of the L1 subfamily and features sequence motifs that may involve CALL in signal transduction pathways.

Abstract
A computational system for the prediction of polymorphic loci directly and efficiently from human genomic sequence was developed and verified. A suite of programs, collectively called POMPOUS (polymorphic marker prediction of ubiquitous simple sequences) detects tandem repeats ranging from dinucleotides up to 250 mers, scores them according to predicted level of polymorphism, and designs appropriate flanking primers for PCR amplification. This approach was validated on an approximately 750-kilobase region of human chromosome 3p21.3, involved in lung and breast carcinoma homozygous deletions. Target DNA from 36 paired B lymphoblastoid and lung cancer lines was amplified and allelotyped for 33 loci predicted by POMPOUS to be variable in repeat size. We found that among those 36 predominately Caucasian individuals 22 of the 33 (67%) predicted loci were polymorphic with an average heterozygosity of 0.42. Allele loss in this region was found in 27/36 (75%) of the tumor lines using these markers. POMPOUS provides the genetic researcher with an additional tool for the rapid and efficient identification of polymorphic markers, and through a World Wide Web site, investigators can use POMPOUS to identify polymorphic markers for their research. A catalog of 13,261 potential polymorphic markers and associated primer sets has been created from the analysis of 141,779,504 base pairs of human genomic sequence in GenBank. This data is available on our Web site (pompous.swmed.edu) and will be updated periodically as GenBank is expanded and algorithm accuracy is improved.

Abstract
Chromosome 3p abnormalities and allele loss are frequent in lung and breast cancers, and several lung cancer cell lines exhibit homozygous deletions of 3p indicating potential sites of tumor suppressor genes at regions 3p21.3, 3p14.2 and 3p12. We have identified and characterized a new 3p21.3 homozygous deletion in a breast cancer cell line and the primary tumor that overlaps those previously described in small cell lung cancer (SCLC). This homozygous deletion is approximately 220 kb in length and represents a somatically acquired change in the primary breast cancer. Cloning and sequencing of the breakpoint demonstrated that this resulted from an interstitial deletion and precisely pinpoints this deletion within the three SCLC homozygous deletions previously reported. This deletion significantly narrows the minimum common deleted region to 120 kb and is distinct from the previously reported region that suppresses tumor formation of the murine A9 fibrosarcoma cells. These findings suggest that a common homozygous deletion region on 3p21.3 is important in both lung and breast cancers. It is likely that this very well characterized region either contains one tumor suppressor gene common to both tumor types or two closely linked tumor suppressor genes specific for each tumor.

Abstract
Using overlapping cosmids representing the vascular endothelial growth factor (VEGF) locus, the VEGF gene was mapped by fluorescence in situ hybridization to chromosome 6p12. This localization permits linkage analysis and the identification of gene interaction in the region, as well as alterations of the VEGF structure or expression in cancer cells with chromosome abnormalities.

Abstract
Semaphorins and collapsins make up a family of conserved genes that encode nerve growth cone guidance signals. We have identified two additional members of the human semaphorin family [human semaphorin A(V) and human semaphorin IV] in chromosome region 3p21.3, where several small cell lung cancer (SCLC) cell lines exhibit homozygous deletions indicative of a tumor suppressor gene. Human semaphorin A(V) has 86% amino acid homology with murine semaphorin A, whereas semaphorin IV is most closely related to murine semaphorin E, with 50% homology. These semaphorin genes are approximately 70 kb apart flanking two GTP-binding protein genes, GNAI-2 and GNAT-1. In contrast, other human semaphorin gene sequences (human semaphorin III and homologues of murine semaphorins B and C) are not located on chromosome 3. Human semaphorin A(V) is translated in vitro into a 90-kDa protein, which accumulates at the endoplasmic reticulum. The human semaphorin A(V) (3.4-kb mRNA) and IV (3.9- and 2.9-kb mRNAs) genes are expressed abundantly but differentially in a variety of human neural and nonneural tissues. Human semaphorin A(V) was expressed in only 1 out of 23 SCLCs and 7 out of 16 non-SCLCs, whereas semaphorin IV was expressed in 19 out of 23 SCLCs and 13 out of 16 non-SCLCs. Mutational analysis in semaphorin A(V) revealed mutations (germ line in one case) in 3 of 40 lung cancers. Our data suggest the need to determine the function of human semaphorins A(V) and IV in nonneural tissues and their role in the pathogenesis of lung cancer.

Abstract
The critical region on human chromosome 3p21.3 harboring a putative lung cancer tumor suppressor gene (TSG) was previously defined by allelotyping and recently refined by overlapping homozygous deletions. We report the construction of a 700-kb (cosmid and one P1 phage) clone contig covering the deletion overlap and its flanks. The minimal set of 23 cosmids comprises 600 kb and is extended by one P1 phage to 700 kb to cover the distal breakpoint of the overlap. The clone contig was extensively characterized by restriction and expression mapping to produce high resolution physical and transcription maps of the cloned region. Potential transcribed fragments were detected by hybridization with PCR-amplified cDNA libraries, direct cDNA selection "zoo" blotting, cDNA screening, and identification of 24 CpG islands. Thus far, 15 new genes represented by partial or full-length cDNAs were isolated, characterized, and precisely positioned on the contig. Two previously cloned genes, namely GNAI-2 and GNAT-1, were also positioned. In addition, the telomeric breakpoint of the NCI H740 deletion and centromeric breakpoint of the overlapping GLC20 deletion were discovered and mapped to define precisely the candidate TSG region. This large cosmid clone contig and high resolution maps will prove crucial in the identification of the lung cancer TSG(s).

Abstract
PURPOSE Members of a family carrying a constitutional balanced translocation [t(3;8) (p14;q24)] have a high risk of developing multiple, bilateral clear-cell renal carcinomas. Two genetic mechanisms of carcinogenesis for this malignancy have been proposed: (1) disruption of a gene at the translocation breakpoint and (2) mutation of the von Hippel-Lindau tumor-suppressor gene at 3p25. This study further evaluates the role of the von Hippel-Lindau gene in the etiology and pathogenesis of t(3;8)-associated renal carcinomas. METHODS Two new t(3;8)-associated renal carcinomas were tested for mutations in the von Hippel-Lindau gene by single-stranded conformational polymorphism analysis followed by direct DNA sequencing, for loss of alleles on chromosomes 3p and 8, and for methylation abnormalities in the first cloned exon of the von Hippel-Lindau gene. RESULTS A missense mutation in the von Hippel-Lindau gene was found in one of the two t(3;8)-associated renal carcinomas. This mutation would produce a stop codon and a truncated protein. Both tumors showed a loss of alleles on the derivative 8 chromosome. When these results were combined with the results of our previous studies, two of the four t(3;8)-associated renal carcinomas, which were examined for molecular genetic changes, showed different von Hippel-Lindau somatic mutations. All renal tumors from the 3;8 translocation family showed loss of the translocated portion of chromosome 3. CONCLUSIONS These results support a mechanism of tumorigenesis in the chromosome (3;8) translocation family that involves the loss of both copies of the von Hippel-Lindau gene.

Abstract
Multiple, bilateral renal carcinomas are a frequent occurrence in von Hippel-Lindau (VHL) disease. To elucidate the aetiological role of the VHL gene in human kidney tumorigenesis, localized and advanced tumours from 110 patients with sporadic renal carcinoma were analysed for VHL mutations and loss of heterozygosity (LOH). VHL mutations were identified in 57% of clear cell renal carcinomas analysed and LOH was observed in 98% of those samples. Moreover, VHL was mutated and lost in a renal tumour from a patient with familial renal carcinoma carrying the constitutional translocation, t(3;8)(p14;q24). The identification of VHL mutations in a majority of localized and advanced sporadic renal carcinomas and in a second form of hereditary renal carcinoma indicates that the VHL gene plays a critical part in the origin of this malignancy.

Abstract
We constructed a genetic map of 96 loci on the short arm of human chromosome 3 (3p) in 59 families provided by the Centre d'Etude du Polymorphisme Humaine (CEPH). Twenty-nine continuously linked loci were placed on the map with likelihood support of at least 1000:1; one locus, D3S213, was placed on the map with likelihood support of 871:1; D3Z1, an alpha satellite centromeric repeat probe, was placed on the map with likelihood support of 159:1; 65 loci were assigned regional locations. The average heterozygosity of the uniquely ordered markers was 49%. The map extends from 3p26, the terminal band of 3p, to the centromere (from D3S211 to D3Z1). Multipoint linkage analysis indicated that the male, female, and sex-averaged maps extend for 102, 147, and 116 cM, respectively. The mean genetic distance between uniquely ordered loci on the sex-averaged map was 4.0 cM. Probe density was greatest for the region of 3p between D3F15S2e and the telomere. The sex-averaged map contained two intervals greater than 10 cM. Seventeen probes were localized by fluorescence in situ hybridization. The loci described in this report will be useful in building an integrated genetic and physical map of this chromosome.

Abstract
Using the human liver cancer DNA transfected NIH/3T3 cell line, the human N-ras oncogene and the over expression of the oncoprotein P21ras was demonstrated, BALB/C mice were immunized. The spleen cells from the immunized mice were fused with SP2/0 myeloma cells. After the HAT medium selection and screening, two hybridoma cell lines, SCI-Oncogema 1 and 2, were established. In the immunoprecipitation test, the molecular weight of the protein reacting to Oncogema 1 was 21,000. This M.W 21,000 protein possessed the capability to bind with GTP, i.e. the character of P21ras. These data indicate that the Oncogema 1 is the monoclonal antibody against P21ras. Using Oncogema 1, specimens from 6 liver cancer patients were studied by immunopathology. With ABC stain, it was observed that the malignant cells in all the samples showed dark staining; the P21ras revealed over expression. Although the staining was heterogeneous, it implied that the ras oncogene was involved in the carcinogenesis of these six samples. No over expression was seen in the normal liver cells even in those around the cancerous lesion. However, dysplastic cells were moderately stained which means that the ras oncogene was activated and P21ras over expressed in these cells. The results suggest that the ras oncogene and P21ras play an important role in the early stage of liver cancer carcinogenesis.
