A Randomized, Double-Blind, Phase III Study in India for Comparing Efficacy, Safety, and PK of ZRC-3277 (Pertuzumab Biosimilar) With Perjeta® in Patients With HER2-Positive Metastatic Breast Cancer.

Introduction: To evaluate the efficacy, safety, pharmacokinetics (PK), and immunogenicity of ZRC-3277 (pertuzumab biosimilar) with Perjeta® (pertuzumab) in previously untreated patients with human epidermal growth factor receptor 2 (HER2)-positive metastatic breast cancer (MBC).

Patients And Methods: This phase III, multicenter, double-blind study across 38 sites in India randomized (1:1) patients with HER2-positive MBC in either the ZRC-3277 or Perjeta® group. Both groups also received trastuzumab and docetaxel.

Nucleotide variability of protamine genes influencing bull sperm motility variables.

Protamines (PRMs), important proteins of chromatin condensation in spermiogenesis, are promising candidate genes to explore markers of sperm motility. The coding and in-silico predicted promoter regions of these genes were investigated in 102 crossbred and 32 purebred cattle. Also, mRNA quantification was done to explore its possibility as diagnostic tool of infertility.

Single Nucleotide Polymorphisms in 5' Upstream Region of Bovine TLR4 Gene Affecting Expression Profile and Transcription Factor Binding Sites.

The present study in the 5' upstream region of TLR4 gene revealed four Single Nucleotide Polymorphisms (SNPs) in Vrindavani and Tharparkar cattle. The polymorphic information content (PIC), heterozygosity and allelic diversity values were low to moderate for these SNPs. In Vrindavani cattle, one SNP was found to be in Hardy-Weinberg Equilibrium (HWE) and the remaining three were found to be in linkage disequilibrium (LD) as indicated statistically (P > 0.

Expression Profiling and Identification of Novel SNPs in CatSper2 Gene and Their Influence on Sperm Motility Parameters in Bovines.

122 randomly selected Vrindavani cattle were studied to detect polymorphism in four fragments of the CatSper2 gene that were comprised of exon 2, 4, 5, and 6 with flanking regions. Using PCR-SSCP and sequencing analysis, three SNPs (T157C, C273A, and A274C) in the first fragment, one SNP (C30G) in the second fragment, and two SNPs (T86G and T292C) in the fourth fragment were identified. The third fragment did not reveal any polymorphism.

Profiling of sperm gene transcripts in crossbred (Bos taurus x Bos indicus) bulls.

Crossbred cattle in some sectors of the world have a significant role in enhancing milk production thereby enhancing the per capita milk availability as a human food source. However, there are certain constraints associated with crossbred animals, such as disease susceptibility, increased reproductive problems, repeat breeding and poor seminal quality. The semen of crossbred bulls has a poor freezing capacity, increased cryo-damage, poor mass cell motility, greater percentages of dead/abnormal sperm and poor initial and post-freeze cell motility.

Sequence Based Structural Characterization and Genetic Diversity Analysis of Full Length TLR4 CDS in Crossbred and Indigenous Cattle.

The exploration of candidate genes for immune response in cattle may be vital for improving our understanding regarding the species specific response to pathogens. Toll-like receptor 4 (TLR4) is mostly involved in protection against the deleterious effects of Gram negative pathogens. Approximately 2.
