Abstract
BACKGROUND Serum thymidine kinase 1 (sTK1) activity is closely correlated with DNA synthesis. OBJECTIVES Evaluate sTK1 activity as a biomarker for treatment response and early detection of relapse in dogs with lymphoma. ANIMALS Ninety-seven client-owned dogs with naive or relapsed lymphoma and 23 healthy dogs. METHODS Prospective study. Serum TK1 activity measured by refined ELISA-based method (DiviTum assay, Biovica International) before treatment, at clinical response, and every 4 weeks until relapse or last follow-up. RESULTS Serum TK1 activity was ≤20 Du/L in 96% (22/23) of healthy dogs. Pretreatment sTK1 activity was >20 Du/L in 88% (85/97) dogs with lymphoma. At clinical response, sTK1 activity was significantly lower in dogs with complete (CR, n = 36) versus partial (PR, n = 29) response (P < .0001). Sensitivity (Se) and specificity (Sp) of sTK1 activity for detecting nonfully responders were 76% and 100%, respectively, with cutoff of 119.5 Du/L (AUC, 0.90; 95%-CI, 0.81-0.98; P < .0001). In dogs with CR, a 5-fold increase in sTK1 activity at a 4-week interval predicted relapse at the subsequent 4-week assessment with a Se 50% and Sp 94% (AUC, 0.72; 95%-CI, 0.55-0.90; P = .02). An increase of sTK1 activity (>2.7-fold value measured at clinical response) predicted relapse at subsequent 4-week assessment with a Se 61% and Sp 88% (AUC, 0.79; 95%-CI, 0.64-0.95; P = .004). CONCLUSIONS AND CLINICAL IMPORTANCE Monitoring sTK1 activity could help to detect complete responders and early disease progression in dogs with lymphoma.

Abstract
The activity of total thymidine kinase in serum (S-TK) has been used as a tumor maker for decades. To date such activity has been determined using [125]I-iodo-deoxyuridine as a substrate. The aim of this study was to develop a new, antibody-based technique for the measurement of cytoplasmic thymidine kinase (TK1) in serum. Both mono- and polyclonal antibodies against S-TK1 were used in dot blot assay. S-TK1 was characterized by SDS and IEF techniques. Sixty-five breast cancer patients were studied, including 17 preoperative and 38 postoperative tumor-free patients and 10 patients with metastases to the lymph nodes (N1–2). They were compared to patients with benign tumors (n=21) and healthy volunteers (n=11). S-TK1 was low (0–1.0 pM) in healthy volunteers, while in preoperative patients the level was increased 6–110-fold. Significant differences were observed between preoperative patients and healthy volunteers (p=0.005), preoperative patients and patients with benign tumors (p<0.001), and preoperative patients and postoperative patients without metastases (p<0.001). No significant difference was observed between preoperative patients and postoperative patients with metastases (p=0.191). The S-TK activity in preoperative patients was also high in serum, but no decrease was observed following surgery. In conclusion, the anti-TK1 antibody could be a good marker for monitoring the response of breast cancer patients to therapy.

Abstract
Background Serum thymidine kinase type 1 (TK1) and canine C‐Reactive Protein (cCRP) might be useful in detecting dogs with cancer. Algorithms combining biomarkers are sometimes more accurate than results of individual tests. Objectives The aim of this study was to compare serum TK1 and cCRP and Neoplasia Index (NI) in healthy and tumor‐bearing dogs. Animals Client‐owned dogs with (n = 253) and without (n = 156) cancer. Methods Retrospective case–control study. Dogs with cancer were identified after submission of samples for commercial assay and case details were retrospectively collected. Healthy dogs (control) were identified through breed groups and health status was confirmed by health questionnaire for a minimum of 6 months. Serum TK1 activity was measured using a quantitative chemiluminescent assay and serum cCRP was measured using a quantitative ELISA assay. Results TK1 activity in the cancer (n = 253) and control group (n = 156) were 7.0 μ/L (median, range <0.5 to >100) and 1.8 μ/L (median, range 0.4 to 55.3), respectively (P < .001). cCRP concentrations in the cancer and control group were 6.0 mg/L (median, range <0.5 to >50) and 1.6 mg/L (median, range 0.09 to >50), respectively (P < .001). The NI in the cancer and control group were 6.4 (median, range 0–9.9) and 0.9 (median, range 0–7.6), respectively (P < .001). ROC AUCs of the NI and TK1 for all cancers were greater than 0.8, highest for lymphoma and histiocytic sarcoma. Conclusions and Clinical Importance Increased concentrations of TK1 and cCRP, when present in dogs with cancer, might be useful in confirming a diagnosis and monitoring response to treatment.

Abstract
While telomerase (hTERT) activity is absent from normal somatic cells, reactivation of hTERT expression is a hallmark of cancer cells. Telomerase activity is required for avoiding replicative senescence and supports immortalization of cellular proliferation. Only a minority of cancer cells rely on a telomerase-independent process known as alternative lengthening of telomeres, ALT, to sustain cancer cell proliferation. Multiple genetic, epigenetic, and viral mechanisms have been found to de-regulate telomerase gene expression, thereby increasing the risk of cellular transformation. Here, we review the different strategies used by the Human T-cell leukemia virus type 1, HTLV-I, to activate hTERT expression and stimulate its enzymatic activity in virally infected CD4 T cells. The implications of hTERT reactivation in HTLV-I pathogenesis and disease treatment are discussed.

Abstract
PURPOSE This study was performed to examine possible use of thymidine kinase 1 concentration in serum (STK1) for prognosis of non-Hodgkin's lymphoma patients following chemotherapy treatment. METHODS The STK1 levels of 37 patients were determined by enhanced chemiluminescent dot-blot assay on the day before chemotherapy, and on day 1 and day 28 after start of the treatment. The specificity and sensitivity was evaluated by Western blot with anti-TK1 IgY antibody and by receiver operating characteristic (ROC) analysis. RESULTS Western blot and ROC analysis of TK1 in serum showed high specificity and sensitivity. The mean STK1 level of the non-Hodgkin's lymphoma patients was significantly higher compared to healthy persons (p < 0.001). The mean STK1 level increased significantly (p < 0.001) on day 1 and then declined, reaching on day 28 values corresponding to those of healthy persons. The mean STK1 values before treatment and at 1 and 28 days after start of the treatment also correlated significantly with the clinical response (CR, PR and NR) and five-year survival. CONCLUSION Although the number of patients was limited in this study, TK1 in serum might possess an important reference value in the evaluation of treatment and prognosis of non-Hodgkin's lymphoma following chemotherapy.

Abstract
Epidemiological studies have demonstrated that the relative percentage of malignant lymphoid proliferations varies widely according to geographical location and ethnic populations. HTLV-I is the etiological agent of adult T-cell leukemia/lymphoma (ATLL) and is also associated with cutaneous T-cell lymphoma (CTCL). However, a definite role of HTLV-I in mycosis fungoides (MF) and/or Sezary syndrome (SS) remains controversial. While most HTLV-I-infected individuals remain asymptomatic carriers, 1-5% will develop ATLL, an invariably fatal expansion of virus-infected CD4+ T cells. This low incidence and the long latency period preceding occurrence of the disease suggest that additional factors are involved in development of ATLL. In this review, diagnosis, clinical features, and molecular pathogenesis of HTLV-I are discussed.

Abstract
More than 2 decades have elapsed since the proposal of adult T-cell leukemia (ATL). Since then, the discovery of the etiologic virus, human T-cell leukemia virus type I (HTLV-I), and the establishment of the diagnostic steps of serum test and molecular study have clearly defined ATL as a distinct disease entity. Because conventional chemotherapy, which is active against other lymphoid malignancies, was proven to be ineffective for treating aggressive forms of ATL, ATL has become the target of several clinical studies for the purpose of improving therapeutic outcomes. Combination chemotherapy exclusively designed for ATL has considerably elevated the treatment response rate in ATL patients, but it has not sufficiently extended the median survival time. The introduction of antiviral agents has led to surprising effects for patients with acute ATL. Monoclonal antibodies seem to be promising, especially for patients with chemotherapy-resistant disease. Unfortunately, these approaches did not prove to be sufficient for most patients with ATL to obtain long-term survival. Recent promising reports on allogeneic stem cell transplantation (allo-SCT) for ATL have suggested that allo-SCT could overcome the limitations that other treatment modalities have not surmounted. More efforts are clearly needed to clarify the usefulness of allo-SCT, especially with reduced-intensity conditioning regimens, for ATL patients.

Abstract
The present study examines the clinical significance of serum neuron-specific enolase (NSE) in patients with adult T cell-leukemia (ATL). Serum NSE values were measured using a radioimmunoassay in 35 patients (acute type, n = 15; lymphoma type, n = 10; chronic type, n = 10) and in 7 controls carrying T lymphotropic virus type-1 (HTLV-1). Serum NSE values >10 ng/mL were detected in 9 of 15 patients with acute type (60%), 5 of 10 with lymphoma type (50%), and in one of 10 patients with chronic type (10%) ATL, but in none of the HTLV-1 carriers. Contrary to previous findings demonstrating that 20% of patients with non-Hodgkin's lymphoma (NHL) had positive serum NSE, the frequency of a high NSE value in patients with acute and lymphoma type ATL was much higher (60% and 50%, respectively). The serum NSE value positively correlated with serum thymidine kinase activity (TK) and serum soluble interleukin-2 receptor (sIL-2R) levels (P < 0.04 and P < 0.01, respectively). Serum NSE values at the initial diagnosis were adversely related to overall survival time according to the log-rank test (P < 0.02). Pathological examinations demonstrated that both patients with anaplastic large cell lymphoma type ATL had cytoplasmic NSE and CD30 markers on cell membranes. These findings suggest that serum NSE is partially produced by ATL cells and that ATL tumor cells seem preferentially produce NSE compared with other NHL cells. Serum NSE may be a novel marker of disease aggressiveness as well as a prognostic factor for ATL.

Abstract
Thymidine kinase is a cell cycle-dependent marker that can be detected in the serum of patients diagnosed with many different types of cancer. Serum levels of thymidine kinase have also been shown to reflect the progression of cancer as well as an indication of the efficacy of chemotherapeutic intervention. A new monoclonal antibody assay for thymidine kinase has been developed, which is capable of detecting thymidine kinase in both serum and tumor tissue. Thymidine kinase assay kits should be available at low cost and could serve as an effective low cost test for the detection and progression of many types of human cancer.

Abstract
The significance of cytomegalovirus (CMV) infections developed over the clinical course of adult T-cell leukemia/lymphoma (ATLL) were evaluated in relation to the patient survival rate, ATL activity and immunocompetent cells. ATLL patients with CMV infections on admission exhibited a poor survival rate, while patients with CMV infections at any time after admission survived longer than those not infected with this virus. ATLL patients who exhibited a numbers of CMV infection on admission showed higher ATL activity and had lower numbers of CD8-positive and CD56-positive cells than those who developed CMV infections at any time after admission. Therefore, it appears likely that patients with CMV infections on admission were in an immunosuppressive state due to aggressive ATL activity.

Abstract
Previous research has shown that thymidine kinase 1 (TK1), a nucleotide salvage pathway enzyme, is an accurate prognostic and diagnostic tumor marker. However, the current radioisotope assay for TK1 is cumbersome and has hampered the clinical application of this diagnostic technique in cancer management. To overcome the problems of the current radioisotope assay, we have produced monoclonal antibodies (MAbs) using purified TK1 from Raji cell extract. Production and confirmation of their specificity was confirmed using Western blot, immunohistochemical staining, TK1 activity inhibition assays, and enzyme-linked immunoadsorbent assay (ELISA) techniques. Thus, in the future, these antibodies may aid in the early detection of cancer and more accurate prognosis, as well as allowing for an increased ability to study the function of TK1 in basic cellular processes.

Abstract
As the clinical manifestations of adult T-cell leukemia (ATL) can be quite diverse, useful indicators for the therapy and prognosis are required for the disease. In this review, the clinical and biological significance of serum tumor markers at diagnosis in ATL patients is described. Serum lactic dehydrogenase (S-LDH), serum thymidine kinase (S-TK) and serum parathyroid hormone-related protein (S-PTHrP) at diagnosis of ATL showed a correlation with among leukocyte count, absolute number of abnormal lymphocytes with polymorphic nuclei, platelet count, serum calcium and the length of survival after the initial diagnosis. Serum beta 2-microglobulin (S-beta 2M) correlated with age, platelet count and survival. A statistical correlation existed between these four serum tumor markers. Other serum tumor markers such as immunosuppressive acidic protein (S-IAP), ferritin (S-Ft) and tissue polypeptide antigen (S-TPA) showed no correlation with clinical and histological data in ATL patients.
