Abstract
Aqueous zinc ion batteries (AZIBs) face significant challenges stemming from Zn dendrite growth and water-contact attack, primarily due to the lack of a well-designed solid electrolyte interphase (SEI) to safeguard the Zn anode. Herein, we report a bio-mass derived polymer of chitin on Zn anode (Zn@chitin) as a novel and robust artificial SEI layer to boost the Zn anode rechargeability. The polymeric chitin SEI layer features both zincophilic and hydrophobic characteristics to target the suppressed dendritic Zn formation as well as the water-induced side reactions, thus harvesting a dendrite-free and corrosion-resistant Zn anode. More importantly, this polymeric interphase layer is strong and flexible accommodating the volume changes during repeated cycling. Based on these benefits, the Zn@chitin anode demonstrates prolonged cycling performance surpassing 1300 h under an ultra-large current density of 20 mA cm-2, and a long cycle life of 680 h with a record-high zinc utilization rate of 80 %. Besides, the assembled Zn@chitin/V2O5 full batteries reveal excellent capacity retention and rate performance under practical conditions, proving the reliability of our proposed strategy for industrial AZIBs. Our research offers valuable insights for constructing high-performance AZIBs, and simultaneously realizes the high-efficient use of cheap biomass from a "waste-to-wealth" concept.

Abstract
AIM This study aimed to investigate whether computed tomography (CT)-measured erector spinae parameters (ESPs) have diagnostic, severity assessment, and prognostic predictive value in uremic sarcopenia (US). MATERIALS AND METHODS A total of 202 uremic patients were enrolled and divided into two groups: a control group and a sarcopenia group. Sarcopenia was classified into two types: severe and nonsevere. The area, volume, and density of the erector spinae (ES) were measured using chest CT images, and the relevant ESP, including the erector spinae index (ESI), total erector spinae volume (TESV), erector spinae density (ESD), and erector spinae gauge (ESG) were calculated. The occurrence of adverse events was followed-up for 36 months. The diagnostic value and severity of US were determined using the receiver operating characteristic (ROC) curve. Survival curves diagnosed using CT were plotted and compared with the curve drawn using the gold standard. Cox regression analysis was used to identify independent risk factors associated with survival in US. RESULTS With an area under the curve (AUC) of 0.840 and 0.739, the combined ESP has diagnostic value and the ability to assess the severity of US. There was no significant difference in the survival curve between the combined ESP for the diagnosis of US and the gold standard (P > 0.05). ESI is a standalone predictor of survival in patients with US. CONCLUSION ESP measured by CT has diagnostic values for US and its severity, as well as being a predictive value for the prognosis of US.

Abstract
The two most commonly used airway management techniques during general anaesthesia are supraglottic airway devices and tracheal tubes. In older patients undergoing elective non-cardiothoracic surgery under general anaesthesia with positive pressure ventilation, we hypothesised that a composite measure of in-hospital postoperative pulmonary complications would be less frequent when a supraglottic airway device was used compared with a tracheal tube. We studied patients aged ≥ 70 years in 17 clinical centres. Patients were allocated randomly to airway management with a supraglottic airway device or a tracheal tube. Between August 2016 and April 2020, 2900 patients were studied, of whom 2751 were included in the primary analysis (1387 with supraglottic airway device and 1364 with a tracheal tube). Pre-operatively, 2431 (88.4%) patients were estimated to have a postoperative pulmonary complication risk index of 1-2. Postoperative pulmonary complications, mostly coughing, occurred in 270 of 1387 patients (19.5%) allocated to a supraglottic airway device and 342 of 1364 patients (25.1%) assigned to a tracheal tube (absolute difference -5.6% (95%CI -8.7 to -2.5), risk ratio 0.78 (95%CI 0.67-0.89); p < 0.001). Among otherwise healthy older patients undergoing elective surgery under general anaesthesia with intra-operative positive pressure ventilation of their lungs, there were fewer postoperative pulmonary complications when the airway was managed with a supraglottic airway device compared with a tracheal tube.

Abstract
Uncontrollable dendrite growth and sluggish ion-transport kinetics are considered as the main obstacles for the further development of high-performance aqueous zinc ion batteries (AZIBs). Here, a nature-inspired separator (ZnHAP/BC) is developed to tackle these issues via the hybridization of the biomass-derived bacterial cellulose (BC) network and nano-hydroxyapatite particles (HAP). The as-prepared ZnHAP/BC separator not only regulates the desolvation process of the hydrated Zn2+ ions (Zn(H2 O)6 2+ ) by suppressing the water reactivity through the surface functional groups, alleviating the water-induced side-reactions, but also boosts the ion-transport kinetics and homogenize the Zn2+ flux, resulting in a fast and uniform Zn deposition. Remarkably, the Zn|Zn symmetric cell with ZnHAP/BC separator harvests a long-term stability over 1600 h at 1 mA cm-2 , 1 mAh cm-2 and endures stable cycling over 1025 and 611 h even at a high depth of discharge (DOD) of 50% and 80%, respectively. The Zn|V2 O5 full cell with a low negative/positive (N/P) capacity ratio of 2.7 achieves a superior capacity retention of 82% after 2500 cycles at 10 A g-1 . Furthermore, the Zn/HAP separator can be totally degraded within 2 weeks. This work develops a novel nature-derived separator and provides insights in constructing functional separators toward sustainable and advanced AZIBs.

Abstract
Weyl semimetals host chiral fermions with distinct chiralities and spin textures. Optical excitations involving those chiral fermions can induce exotic carrier responses, and in turn lead to novel optical phenomena. Here, we discover strong coherent terahertz emission from Weyl semimetal TaAs, which is demonstrated as a unique broadband source of the chiral terahertz wave. The polarization control of the THz emission is achieved by tuning photoexcitation of ultrafast photocurrents via the photogalvanic effect. In the near-infrared regime, the photon-energy dependent nonthermal current due to the predominant circular photogalvanic effect can be attributed to the radical change of the band velocities when the chiral Weyl fermions are excited during selective optical transitions between the tilted anisotropic Weyl cones and the massive bulk bands. Our findings provide a design concept for creating chiral photon sources using quantum materials and open up new opportunities for developing ultrafast opto-electronics using Weyl physics.

Abstract
Objective: To describe the characteristics of the nodular type of pulmonary cryptococcosis (PC) with coexisting lung cancer. Methods: A total of 9 cases of PC with coexisting lung cancer, admitted to Fuzhou Pulmonary Hospital of Fujian from 1st January 2009 to 31th December 2016, and confirmed by pathological examinations, were studied and the related literature were reviewed. Results: The patients consisted of 1 male and 8 females, with a mean age of (53±10) years (range, 38 to 68 years). Four patients (44.4%) had underlying diseases, 3 with diabetes mellitus and 1 with gastric cancer surgery. The main clinical manifestations of most cases were cough and phlegm. The lesions of PC on chest CT were mostly solitary or multiple nodules with a diameter < 1 cm, and the lesions of carcinoma were shown as solitary nodules with a variety of signs suggestive of malignancy. All the patients were confirmed to have concomitant PC and lung adenocarcinoma by pathological examinations. Lung cancer stage was early (Tis and Ⅰ-Ⅱ) in 88.9 % (8 cases) of the cases. All the patients received surgery and postoperative medical therapy. The prognosis was relatively good in most of them except 1 case with death due to lung cancer metastasis and 1 case with lung cancer recurrence. Conclusions: Coexistence of PC and lung cancer is rare and the clinical symptoms are not specific. When PC coexists with carcinoma and manifests as pulmonary nodule, it mimics malignant lesions and is extremely easy to be misdiagnosed. Therefore PC must be considered in the differential diagnosis of pulmonary nodules.

Methods: From January 2009 to July 2018, the clinical data of 62 patients with biliary or pancreatic long-term complications after pancreatoduodenectomy were reviewed at Department of General Surgery, and the corresponding ERCP were carried out in the multi-disciplinary cooperation.There were 39 males and 24 females.The age was 56.5 years(aging from 13 to 76 years). The time of treatment was 3 months to 20 years after pancreatoduodenectomy.The long-term biliopancreatic complications after pancreatoduodenectomy included 51 cases of biliary calculi, 42 cases of bilioenteric anastomotic stenosis with proximal bile duct dilatation, and 11 cases of pancreaticointestinal anastomosis stenosis with distal pancreatic duct dilatation.All patients received conventional duodenoscopy or single-balloon enteroscopy assisted ERCP under general anesthesia. Results: A total of 95 ERCP were performed in 62 patients, averaging 1.5 times per case.The long-term complications of cholangiopancreatic after pancreatoduodenectomy(ERCP indications) included 56 times of bile duct stones(58.9%), 45 times of bilioenteric anastomatic stricture(47.4%), 11 times of recurrent pancreatitis(11.6%), 6 cases(6.3%) of bilioenteric anastomatic foreign body, 3 times of intrahepatic bile duct stenosis(3.2%). Among the 95 times, 82 times(86.3%) achieved endoscopic endoscopy, 76 times(80.0%) were diagnosed successfully, and 72 times(75.8%) were successfully treated with ERCP.Small intestinal perforation occurred in 1 patient undergoing duodenoscopy, and then healed by surgical repair. Conclusion: Multi-disciplinary collaboration of ERCP is safe and effective in the treatment of long-term complications after pancreaticoduodenectomy, but the long-term effect still needs further clinical follow-up.

Abstract
BACKGROUND Clinical trials of investigational drugs for Alzheimer disease (AD) increasingly focus on the prodromal (symptomatic) stage of the illness and now its preclinical (asymptomatic) stage. Sensitive and specific cognitive and functional endpoints are needed to track subtle cognitive and functional changes in the early and preclinical stages to minimize sample sizes in these trials. OBJECTIVES To identify informative items in a standard clinical assessment protocol and a psychometric battery that are predictive of onset of dementia symptom. DESIGN Longitudinal retrospective study. SETTING Washington University (WU) Knight Alzheimer Disease Research Center (ADRC). PARTICIPANTS A total of 735 individuals at least 65 years old and cognitively normal at baseline from a longitudinal clinical cohort at the WU Knight ADRC. MEASUREMENTS The annual clinical assessment included a wide spectrum of functional and cognitive domains; a comprehensive psychometric battery was completed about 2 weeks after the clinical evaluation. Psychometricians are blinded to the results of the clinical evaluation and to the prior performance of the participants on the psychometric tests. RESULTS The mean age at baseline of the 735 participants was 74.30 and 62.31% were female. 240 individuals developed prodromal dementia symptoms (consistent with mild cognitive impairment due to AD and with very mild AD dementia) during longitudinal follow-up (mean follow-up=6.79 years). Among a total of 562 items in the clinical and cognitive assessments under analysis, 292 (52%) were identified as informative because their longitudinal changes were predictive of symptomatic onset. When these items were used to form the functional and cognitive composites, the longitudinal rates of changes were free of a learning effect and captured subtle longitudinal progression prior to symptomatic onset. The rates of change were much greater right after the symptomatic onset than those from the functional and cognitive composites formed using non-informative items. Although the sample sizes for prevention trials (prior to symptomatic onset) using the informative items still yield large numbers, the sample sizes for early treatment trial (after symptomatic onset) was much smaller than those derived from all the items or from the non-informative items alone. CONCLUSIONS The antecedent longitudinal changes in nearly half of the items in a clinical assessment protocol and a comprehensive cognitive battery did not show statistically significant ability to predict the dementia symptom onset, and hence may be non-informative to track the preclinical functional and cognitive progression of AD. The remaining items, on the other hand, captured some of the preclinical changes prior to the symptom onset, but performed much better right after the symptom onset. Currently ongoing prevention trials on preclinical AD of elderly individuals may need to re-assess the sample sizes and statistical power.

Abstract
Meta-analysis used for genetic association studies became popular among researchers, with the amount of published papers increased rapidly. In this paper, we will focus on the introduction on the selection of genetic models. Traditionally, methods used for Meta-analysis on genetic association studies was to calculate the statistics based on available genetic models which not only increasing the probability of false-positives but also making the interpretation of results more difficult. Hence, a critical step in the Meta-analysis of genetic association studies was to choose the appropriate inheritance model. The aim of this paper was to introduce the theory of Bayesian analysis regarding the genetic model-free approach, in performing the Meta-analysis for studies related to genetic associations.

Abstract
Objective: To study the value of an early (mechanical ventilation after 24 h) non-sedation protocol for intubated, mechanically ventilated patients in the respiratory intensive care unit (RICU). Methods: Seventy intubated, mechanically ventilated patients were prospectively enrolled and randomly assigned to management with early non-sedation (intervention group; n=35) or with daily interruption of sedation (DIS) (control group; n=35). The duration of mechanical ventilation, length of the RICU and hospital stay, RICU and hospital mortality, drug consumption, RICU and hospitalization expenses, incidence of complications and adverse events and serum levels of vital organ damage and inflammatory markers after mechanical ventilation for 48 h were recorded and compared. Results: Patients in the intervention group had a shorter duration of mechanical ventilation than those in the control group [(7±5) vs (11±9) d, P<0.05] and were discharged from the RICU [(9±7) vs (18±9) d, P<0.05] and hospital earlier [(17±14) vs (29±22) d, P<0.05] than those in the control group. The doses of midazolam were significantly lower in the intervention group than in the control group [(99±104) vs (482±337) mg, P<0.05]. The RICU and hospitalization expenses were both significantly lower in the intervention group than in the control group [53(84) vs 88(173), 72(195) vs 154(234) thousand CHY, P<0.05]. In the intervention group, the occurrence rates of ventilator associated pneumonia (23% vs 46%), tracheotomy (14% vs 37%) and gastrointestinal adverse reactions (17% vs 40%) were significantly lower than those in the control group (P<0.05). No differences were recorded in RICU and hospital mortality (P>0.05). The occurrence rates of unplanned extubation and reintubation and the need for CT brain scans were similar in the 2 groups (P>0.05). The levels of cardiac, liver and renal damage markers, lactic acid and C-reactive protein were the same in both groups (P>0.05). Conclusions: The early non-sedation protocol decreased the duration of mechanical ventilation and the length of stay in the RICU and hospital, and it did not increase the incidence of complications and adverse events.

Abstract
Characteristics of gonadal development were investigated in Muscovy duck embryos at various embryonic ages. Hematoxylin-Eosin and periodic acid-Schiff staining were used to identify primordial germ cells, oogonia and sustentacular cells. Gene specific primers were designed based on conserved regions of duck antimullerian hormone (AMH), oestrogen receptor-α (ESR-α), doublesex and Mab-3 related transcription factor-1(DMRT1) and W chromosome protein kinase C inhibitor/interacting gene (WPKCI). Quantitative real-time polymerase chain reaction was used to characterise gene expression during gonad development in Muscovy duck embryos. Histology indicated that ovarian and testicular cells of Muscovy duck embryos developed on d 9 and 10. Immunohistochemistry showed that mouse vasa homologue-positive cells as well as Glial cell line-derived neurotrophic factor-positive cells increased significantly more in females than in males between d 9 and 10. AMH and ESR-α expression increased significantly during early development. DMRT1 acts prior to and during testis differentiation whereas WPKCI was expressed actively in the female Muscovy duck embryo before the onset of gonadal differentiation. Gonad development in Muscovy duck embryo was associated with several genes that were expressed before morphological features appear and were gender specific.

Abstract
OBJECTIVE DESs have been proved to be beneficial for patients with chronic total coronary occlusions (CTO) in terms of cardiac function and other prognosis. We aim to compare the efficacy and safety of drug-eluting stent (DES) and bare-metal stent (BMS) in CTO recanalization at different follow-up duration. METHODS Articles comparing outcomes between DES and BMS implantation in patients with CTO was searched. A fixed-effect (inverse-variance weighted) and random-effect (DerSimonian and Laird) model were used to analyze the pooling results. RESULTS A total of 29 comparative studies including 24 cohort studies and 5 randomized controlled studies were identified with a total of 9140 patients (5008 received BMS and 4132 received DES). The risk of all cause death for DES was higher at 6 months and lower at 12 months than BMS, and no significant difference was shown at 24, 36 and 60 months. DES group had lower risk of MI after 12 months implantation, and no difference was shown at 6, 24, 36 and 60 months. Major adverse cardiovascular event (MACE)-free survival was clinically and significantly improved by 73%, 68%, 49%, 40% and 37% respectively in DES group at 6,12, 24, 36, and 60 months. CONCLUSIONS DES is superior to BMS in binary restenosis, reocclusion and MACE-free survival during long-term follow up. The occurrences of all-cause death and MI show that the risk rate of BMS is higher than that of DES at 12 months. The frequency of all-cause death of DES is higher than BMS at 6 months. DES has higher risk of in-stent thrombosis than BMS at 36 months of implantation.

Abstract
High mobility group box B1 (HMGB1)-receptor for advanced glycation end products (RAGE) axis has been previously known to be involved in carcinogenesis and development of multiple malignancies. Some studies have confirmed that Ethyl pyruvate (EP), a potent inhibitor of HMGB1, exerts the therapeutic effects on metastatic live tumor from gastric cancer. However, the effects and possible molecular mechanisms of EP on gallbladder cancer (GBC) need to be further explored. In the present study, human GBC cell lines (GBC-SD and SGC-996) were treated with different concentrations of EP. Then, the expression levels of HMGB1, RAGE and some transcription factors were identified by Real-time PCR and Western blot assays. Cell proliferative activities indicated by MTT assay, invasive potential by Transwell assay and cell apoptosis and cycle distribution were performed for functional analysis of GBC cell lines in vitro. As a result, EP decreased the expression of HMGB11, RAGE, PCNA and matrix metallopeptidase-9 (MMP-9), while it increased the expression of p53. Moreover, EP administration decreased GBC cell proliferation, inhibited the invasive potential, and induced apoptosis and cycle arrest in S phase in GBC cells. In conclusion, EP administration inhibits growth and invasion of gallbladder cancer cells possibly via down-regulation of the HMGB1-RAGE axis, suggesting that EP may play a critical role in the treatment of cancer in conjunction with other therapeutic agents.

Abstract
OBJECTIVE To observe histological changes of hepatic fibrosis patients with chronic hepatitis B after recombinant human interferon-gamma treatment. METHODS Twenty hepatic fibrosis patients with chronic hepatitis B received rhIFN-gamma treatment at the dose of 1 MU intramuscularly daily for the first three months and every other day for the next six months. Liver biopsy was performed at the start of the therapy and the end of 9-month follow-up period respectively in all patients. All liver biopsy specimens were stained with hematoxylin-eosin and picro-sirius red. Modified Scheuer and Chevallier semi-quantitative scoring system was used to assess the results. In the meantime, serum hepatic fibrosis indices and serum biochemical examination were detected. RESULTS After 9 moths of treatment, the mean fibrosis score decreased from 11.24 +/- 5.34 to 8.67 +/- 4.16 (P<0.01), whereas the mean inflammation score decreased from 12.78 +/- 5.19 to 6.57 +/- 2.95 (P<0.01). CONCLUSIONS rhIFN-gamma showes a beneficial effect on hepatic fibrosis patients with chronic hepatitis B.

Abstract
OBJECTIVE To find the relationship between serum levels of hyaluronic acid (HA), type III procollagen (PC III), laminin (LN), type IV collagen (IV-C) and hepatic fibrosis as well as to determine their value in clinical practice. METHODS 2600 serum samples from chronic hepatitis patients were tested with RIA for fibrosis indexes assays including HA, PC III, LN and IV-C. 280 of the patients with serum samples taken had liver biopsy performed and the biopsy material was examine pathomorphologically. Fibrosis indexes were compared according to inflammation grade, fibrosis stage and chronic hepatitis degree. RESULTS In the 2600 serum samples from chronic hepatitis patients, fibrosis indexes (including HA, PC III, LN and IV-C) had significant correlation with inflammation grade, fibrosis stage and the degree of chronic hepatitis (P < 0.01). The relating indexes to HA were 0.544, 0.548, 0.468 respectively, to PC III 0.495, 0.424, 0.335 respectively, to LN 0.214, 0.204, 0.184 and to IV-C were 0.464, 0.404, 0.412 respectively. CONCLUSION Serum fibrosis indexes are fairly well correlated with the inflammation grade, fibrosis stage and the degree of chronic hepatitis. However, as diagnostic markers, they must be combined with liver function, ultrasonography and clinical features.

Abstract
Moloney murine leukemia virus (Mo-MuLV) is a thymotropic and leukemogenic retrovirus which causes T lymphomas. Recently, Mo-MuLV has been shown to trans-activate cellular genes. Monocyte chemoattractant protein-1 (MCP-1) is a chemokine which can promote the migration and diapedesis of monocytes and lymphocytes, as well as inducing metastasis of lymphomas. Here we demonstrate that introduction of Mo-MuLV or the MuLV LTR alone, transiently or stably, into Balb/c-3T3 cells or HeLa cells resulted in 9-11 fold increases in MCP-1 transcripts. This trans-activation of the MCP-1 gene by the Mo-MuLV LTR is independent of the physical location of the MCP-1 gene or of the LTR, occurring whether the LTR or the MCP-1 gene is integrated in the genome or transiently expressed. Immunoblot analysis using an anti-MCP-1 polyclonal antibody showed that the expression of the MuLV LTR in HeLa cells also induced the appearance of the MCP-1 protein. Boyden Chamber analysis demonstrated that the MCP-1 chemotactic activity produced by HeLa cells with an integrated MuLV LTR was elevated by 11 fold and that neutralizing antibody to human MCP-1 abrogated monocyte migration in response to MuLV LTR expression. Promoter deletional analysis showed the LTR responsive cis-acting element in the MCP-1 promoter is located between -141 and -88. Deletion of this region abolished the trans-activation of MCP-1 by the LTR. These LTR-mediated activations of a chemotactic and inflammatory cytokine may be relevant as mechanisms whereby retroviruses which do not contain oncogenes can induce neoplasia.

Abstract
Moloney murine leukemia virus (Mo-MuLV) is a thymotropic and leukemogenic retrovirus which causes T lymphomas and leukemias, yet does not contain a transforming gene product. Mo-MuLV has been shown to trans-activate cellular genes via a polymerase III-generated transcript, designated let, from the long terminal repeat (LTR). Here we demonstrate that introduction of the Mo-MuLV LTR stably, or transiently, into murine or human cultured cells resulted in an 8- to 15-fold increase in collagenase IV (92-kDa gelatinase, gelatinase B, matrix metalloproteinase-9) gene expression. Collagenase IV protein expression was induced 9-fold by stable integration of MuLV LTR, as measured by immunoblot analysis using an anti-collagenase IV polyclonal antibody. The MuLV LTR coordinately stimulated the proteolytic activity of collagenase IV by 14-fold. The AP-1-binding site in the collagenase IV promoter was required for transactivation by the LTR. Collagenase type IV degrades type IV collagen, a major component of basement membrane, which constitutes the first step of the metastatic cascade. The activation of proteolytic enzymes by the MuLV LTR may thus play a contributory role in the development or spread of virus-induced lymphomas or leukemias.

Abstract
Moloney murine leukemia virus (Mo-MuLV) is a thymotropic and leukemogenic retrovirus which causes T lymphomas. The long terminal repeat (LTR) of Mo-MuLV affects the regulation of a number of cellular genes, including collagenase IV, monocyte chemoattractant protein-1, and c-jun genes, all of which contain 12-O-tetradecanoylphorbol-13-acetate-responsive element consensus sites within their promoters. We report here that Mo-MuLV stimulates the collagenase IV gene through transcription factor AP-1, and that the expression of a subgenomic portion of Mo-MuLV LTR alone is sufficient for this effect. Transient or stable expression of the viral LTR increases cellular AP-1 DNA binding activity. The collagenase IV 12-O-tetradecanoylphorbol-13-acetate-responsive element consensus sequence was shown to be required for this trans-activation. Deletions or mutations of this consensus site which abolished AP-1 binding also abolished trans-activation by the LTR. Transient or stable transfection of the viral LTR into cells stimulated c-jun gene expression, suggesting one mechanism whereby the viral LTR may induce cellular AP-1 activity. Thus, the Mo-MuLV LTR, through activation of the transcription factor AP-1, is capable of regulating cellular gene expression, including the induction of proto-oncogenes. This activity may be relevant to the mechanisms whereby retroviruses which do not contain oncogenes induce neoplasia.

Abstract
Autophosphorylation of the platelet-derived growth factor (PDGF) receptor on tyrosine, which is dependent upon and occurs immediately after ligand binding, has been linked to the activation of second messenger pathways thought to be necessary for the induction of gene expression, DNA synthesis, and mitogenesis. We have investigated PDGF signal transduction in Balb/c3T3 and NIH-3T3 cells at the level of immediate-early gene induction under three conditions in which PDGF receptor autophosphorylation in response to PDGF binding is blocked: cells transformed by v-rasKi, cells transformed by v-mos, and cells treated with genistein, a specific inhibitor of tyrosine kinases. PDGF induction of immediate-early genes c-myc, c-fos, and JE is blocked in these systems. Induction of another immediate-early gene, egr-1, occurs normally despite the absence of measurable tyrosine kinase activity. The same results were obtained when cells were stimulated with PDGF-AA or PDGF-BB. It is not yet clear if this receptor tyrosine kinase-independent signal utilizes known PDGF second messengers, but these results demonstrate a new arm of the PDGF signal transduction pathway which operates in the absence of, and independently from, autophosphorylation of the receptor on tyrosine.
