Terminal deoxynucleotidyltransferase. Serological studies and radioimmunoassay [PDF]

open access: yes, 1976
Mouse antisera against calf terminal deoxynucleotidyltransferase (terminal transferase) have been prepared. The sera have been used to characterize terminal transferase both by studying inhibition of enzyme activity and by developing a competition ...

Bovine Leukemia Virus Involvement In Enzootic Bovine Leukosis

open access: yes, 1978
Publisher Summary Enzootic bovine leukosis is a contagious disease induced by bovine leukemia virus (BLV). It is a chronic disease that develops over a long period and can be schematically divided into three phases: (1) from birth to infection (some animals are already infected at birth), (2) from viral infection to tumorous transformation (a number ...

Microfluidic Hydroporation Platform for Effective Allogeneic CAR‐T Cell Production and Subsequent Functional Cytotoxicity Analysis

open access: yesAdvanced Materials Technologies, EarlyView.
The hydroporator platform employs controlled hydrodynamic deformation for efficient mRNA and CRISPR/Cas9 delivery into primary human T cells, enabling allogeneic CAR‐T cell manufacturing. It preserves cell functionality and drives potent gene editing, CAR expression, and tumor cytotoxicity, while feature‐based analysis links these functional outcomes ...

Possible immunoenhancement of persistent viremia by feline leukemia virus envelope glycoprotein vaccines in challenge-exposure situations where whole inactivated virus vaccines were protective. [PDF]

open access: yes, 1986
Kittens immunized with purified native FeLV-gp70 or -gp85 envelope proteins developed ELISA, but not virus neutralizing, antibodies in their serum to both whole FeLV and FeLV-gp70.

Chronic Hypoxia Disrupts Spermatogenesis Through ASXL2–EZH2–Mediated Microtubule Destabilization

open access: yesAdvanced Science, EarlyView.
This study reveals the mechanism by which chronic hypoxia impairs spermatogenesis via the ASXL2–EZH2 axis, hindering the transition of spermatids from round to elongated forms. Key findings reveal that under hypoxic conditions, downregulated ASXL2 expression reduces EZH2 binding to the CEP162 promoter, leading to decreased H3K27me3 modification and ...

Bovine Leukemia Virus Infection and Mastitis

open access: yesJournal of Dairy Science, 1982
Adult dairy cows (226 head) in three herds were sampled both for bovine leukemia virus infection and for mastitis infection. A chi square analysis revealed no statistically significant association between the two types of infection.

Logic‐Gated HSV‐TK/GCV Suicide Gene Circuit for Triple‐Negative Breast Cancer

open access: yesAdvanced Science, EarlyView.
The BRAS comprises two modular genetic components driven by distinct tumor‐specific promoters and a failsafe layer with the NOT gate. This multi‐input logic gate circuit enables precise, specific expression of HSV‐TK in breast cancer cells with hardly expression in normal cell and effectively inhibits tumor growth in a triple‐negative breast cancer ...

MODERN METHODS AND EXPERIENCE OF STRUGGLE AGAINST LEUKEMIA OF CATTLE

open access: yesВ мире научных открытий, 2018
The article presents the main methods of diagnosis and control of the bovine leukemia virus currently used. The wide spread of the disease is due to a fairly easy transmission of the virus, the lack of early diagnosis, vaccination and treatment ...
